Cell surface glycoproteins that bind to chemokines and thus mediate the migration of pro-inflammatory molecules. The receptors are members of the seven-transmembrane G protein-coupled receptor family. Like the CHEMOKINES themselves, the receptors can be divided into at least three structural branches: CR, CCR, and CXCR, according to variations in a shared cysteine motif.
A CC-type chemokine that is a chemoattractant for EOSINOPHILS; MONOCYTES; and LYMPHOCYTES. It is a potent and selective eosinophil chemotaxin that is stored in and released from PLATELETS and activated T-LYMPHOCYTES. Chemokine CCL5 is specific for CCR1 RECEPTORS; CCR3 RECEPTORS; and CCR5 RECEPTORS. The acronym RANTES refers to Regulated on Activation, Normal T Expressed and Secreted.
Macrophage Inflammatory Proteins
Heparin-binding proteins that exhibit a number of inflammatory and immunoregulatory activities. Originally identified as secretory products of MACROPHAGES, these chemokines are produced by a variety of cell types including NEUTROPHILS; FIBROBLASTS; and EPITHELIAL CELLS. They likely play a significant role in respiratory tract defenses.
Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner.
Monocyte Chemoattractant Proteins
Duffy Blood-Group System
A platelet-specific protein which is released when platelets aggregate. Elevated plasma levels have been reported after deep venous thrombosis, pre-eclampsia, myocardial infarction with mural thrombosis, and myeloproliferative disorders. Measurement of beta-thromboglobulin in biological fluids by radioimmunoassay is used for the diagnosis and assessment of progress of thromboembolic disorders.
Intercellular Signaling Peptides and Proteins
Regulatory proteins and peptides that are signaling molecules involved in the process of PARACRINE COMMUNICATION. They are generally considered factors that are expressed by one cell and are responded to by receptors on another nearby cell. They are distinguished from HORMONES in that their actions are local rather than distal.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Platelet Factor 4
A CXC chemokine that is found in the alpha granules of PLATELETS. The protein has a molecular size of 7800 kDa and can occur as a monomer, a dimer or a tetramer depending upon its concentration in solution. Platelet factor 4 has a high affinity for HEPARIN and is often found complexed with GLYCOPROTEINS such as PROTEIN C.
A CX3C chemokine that is a transmembrane protein found on the surface of cells. The soluble form of chemokine CX3CL1 can be released from cell surface by proteolysis and act as a chemoattractant that may be involved in the extravasation of leukocytes into inflamed tissues. The membrane form of the protein may also play a role in cell adhesion.
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS. (from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Gene Expression Regulation
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
Tumor Necrosis Factor-alpha
Serum glycoprotein produced by activated MACROPHAGES and other mammalian MONONUCLEAR LEUKOCYTES. It has necrotizing activity against tumor cell lines and increases ability to reject tumor transplants. Also known as TNF-alpha, it is only 30% homologous to TNF-beta (LYMPHOTOXIN), but they share TNF RECEPTORS.
Reverse Transcriptase Polymerase Chain Reaction
The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.
Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Cell Migration Inhibition
Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.
Disease Models, Animal
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)
Specialized cells of the hematopoietic system that have branch-like extensions. They are found throughout the lymphatic system, and in non-lymphoid tissues such as SKIN and the epithelia of the intestinal, respiratory, and reproductive tracts. They trap and process ANTIGENS, and present them to T-CELLS, thereby stimulating CELL-MEDIATED IMMUNITY. They are different from the non-hematopoietic FOLLICULAR DENDRITIC CELLS, which have a similar morphology and immune system function, but with respect to humoral immunity (ANTIBODY PRODUCTION).
A molecule that binds to another molecule, used especially to refer to a small molecule that binds specifically to a larger molecule, e.g., an antigen binding to an antibody, a hormone or neurotransmitter binding to a receptor, or a substrate or allosteric effector binding to an enzyme. Ligands are also molecules that donate or accept a pair of electrons to form a coordinate covalent bond with the central metal atom of a coordination complex. (From Dorland, 27th ed)
The process in which the neutrophil is stimulated by diverse substances, resulting in degranulation and/or generation of reactive oxygen products, and culminating in the destruction of invading pathogens. The stimulatory substances, including opsonized particles, immune complexes, and chemotactic factors, bind to specific cell-surface receptors on the neutrophil.
Bronchoalveolar Lavage Fluid
Chemotactic Factors, Eosinophil
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Subset of helper-inducer T-lymphocytes which synthesize and secrete interleukin-2, gamma-interferon, and interleukin-12. Due to their ability to kill antigen-presenting cells and their lymphokine-mediated effector activity, Th1 cells are associated with vigorous delayed-type hypersensitivity reactions.
Gene Expression Profiling
Amino Acid Sequence
Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
Intercellular Adhesion Molecule-1
A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.
A critical subpopulation of T-lymphocytes involved in the induction of most immunological functions. The HIV virus has selective tropism for the T4 cell which expresses the CD4 phenotypic marker, a receptor for HIV. In fact, the key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T-lymphocytes.
Movement of tethered, spherical LEUKOCYTES along the endothelial surface of the microvasculature. The tethering and rolling involves interaction with SELECTINS and other adhesion molecules in both the ENDOTHELIUM and leukocyte. The rolling leukocyte then becomes activated by CHEMOKINES, flattens out, and firmly adheres to the endothelial surface in preparation for transmigration through the interendothelial cell junction. (From Abbas, Cellular and Molecular Immunology, 3rd ed)
Oligonucleotide Array Sequence Analysis
Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.
Receptors, Cell Surface
Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.
Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.
Cell Adhesion Molecules
Culture Media, Conditioned
Vascular Cell Adhesion Molecule-1
Cytokine-induced cell adhesion molecule present on activated endothelial cells, tissue macrophages, dendritic cells, bone marrow fibroblasts, myoblasts, and myotubes. It is important for the recruitment of leukocytes to sites of inflammation. (From Pigott & Power, The Adhesion Molecule FactsBook, 1993, p154)
White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.
A large group of structurally diverse cell surface receptors that mediate endocytic uptake of modified LIPOPROTEINS. Scavenger receptors are expressed by MYELOID CELLS and some ENDOTHELIAL CELLS, and were originally characterized based on their ability to bind acetylated LOW-DENSITY LIPOPROTEINS. They can also bind a variety of other polyanionic ligand. Certain scavenger receptors can internalize micro-organisms as well as apoptotic cells.
Measurable and quantifiable biological parameters (e.g., specific enzyme concentration, specific hormone concentration, specific gene phenotype distribution in a population, presence of biological substances) which serve as indices for health- and physiology-related assessments, such as disease risk, psychiatric disorders, environmental exposure and its effects, disease diagnosis, metabolic processes, substance abuse, pregnancy, cell line development, epidemiologic studies, etc.
A family of pattern recognition receptors characterized by an extracellular leucine-rich domain and a cytoplasmic domain that share homology with the INTERLEUKIN 1 RECEPTOR and the DROSOPHILA toll protein. Following pathogen recognition, toll-like receptors recruit and activate a variety of SIGNAL TRANSDUCING ADAPTOR PROTEINS.
Antibodies that inhibit the reaction between ANTIGEN and other antibodies or sensitized T-LYMPHOCYTES (e.g., antibodies of the IMMUNOGLOBULIN G class that compete with IGE antibodies for antigen, thereby blocking an allergic response). Blocking antibodies that bind tumors and prevent destruction of tumor cells by CYTOTOXIC T-LYMPHOCYTES have also been called enhancing antibodies. (Rosen et al., Dictionary of Immunology, 1989)
The mucous membrane lining the RESPIRATORY TRACT, including the NASAL CAVITY; the LARYNX; the TRACHEA; and the BRONCHI tree. The respiratory mucosa consists of various types of epithelial cells ranging from ciliated columnar to simple squamous, mucous GOBLET CELLS, and glands containing both mucous and serous cells.
Toll-Like Receptor 4
The third type of glial cell, along with astrocytes and oligodendrocytes (which together form the macroglia). Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies. They have also been suggested to act in several other roles including in secretion (e.g., of cytokines and neural growth factors), in immunological processing (e.g., antigen presentation), and in central nervous system development and remodeling.
Toll-Like Receptor 2
INFLAMMATION of the PERITONEUM lining the ABDOMINAL CAVITY as the result of infectious, autoimmune, or chemical processes. Primary peritonitis is due to infection of the PERITONEAL CAVITY via hematogenous or lymphatic spread and without intra-abdominal source. Secondary peritonitis arises from the ABDOMINAL CAVITY itself through RUPTURE or ABSCESS of intra-abdominal organs.
A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.
Dose-Response Relationship, Drug
Bone Marrow Cells
Killer Cells, Natural
Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.
A cytokine produced by a variety of cell types, including T-LYMPHOCYTES; MONOCYTES; DENDRITIC CELLS; and EPITHELIAL CELLS that exerts a variety of effects on immunoregulation and INFLAMMATION. Interleukin-10 combines with itself to form a homodimeric molecule that is the biologically active form of the protein.
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
Mice homozygous for the mutant autosomal recessive gene "scid" which is located on the centromeric end of chromosome 16. These mice lack mature, functional lymphocytes and are thus highly susceptible to lethal opportunistic infections if not chronically treated with antibiotics. The lack of B- and T-cell immunity resembles severe combined immunodeficiency (SCID) syndrome in human infants. SCID mice are useful as animal models since they are receptive to implantation of a human immune system producing SCID-human (SCID-hu) hematochimeric mice.
Intercellular signaling peptides and proteins that regulate the proliferation of new blood vessels under normal physiological conditions (ANGIOGENESIS, PHYSIOLOGICAL). Aberrant expression of angiogenic proteins during disease states such as tumorigenesis can also result in PATHOLOGICAL ANGIOGENESIS.
Diffusion Chambers, Culture
Devices used in a technique by which cells or tissues are grown in vitro or, by implantation, in vivo within chambers permeable to diffusion of solutes across the chamber walls. The chambers are used for studies of drug effects, osmotic responses, cytogenic and immunologic phenomena, metabolism, etc., and include tissue cages.
The process of altering the morphology and functional activity of macrophages so that they become avidly phagocytic. It is initiated by lymphokines, such as the macrophage activation factor (MAF) and the macrophage migration-inhibitory factor (MMIF), immune complexes, C3b, and various peptides, polysaccharides, and immunologic adjuvants.
Epidermal cells which synthesize keratin and undergo characteristic changes as they move upward from the basal layers of the epidermis to the cornified (horny) layer of the skin. Successive stages of differentiation of the keratinocytes forming the epidermal layers are basal cell, spinous or prickle cell, and the granular cell.
Integrin alpha4beta1 is a FIBRONECTIN and VCAM-1 receptor present on LYMPHOCYTES; MONOCYTES; EOSINOPHILS; NK CELLS and thymocytes. It is involved in both cell-cell and cell- EXTRACELLULAR MATRIX adhesion and plays a role in INFLAMMATION, hematopoietic cell homing and immune function, and has been implicated in skeletal MYOGENESIS; NEURAL CREST migration and proliferation, lymphocyte maturation and morphogenesis of the PLACENTA and HEART.
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
A heterodimeric cytokine that plays a role in innate and adaptive immune responses. Interleukin-12 is a 70 kDa protein that is composed of covalently linked 40 kDa and 35 kDa subunits. It is produced by DENDRITIC CELLS; MACROPHAGES and a variety of other immune cells and plays a role in the stimulation of INTERFERON-GAMMA production by T-LYMPHOCYTES and NATURAL KILLER CELLS.
Isolation of novel GRO genes and a phylogenetic analysis of the CXC chemokine subfamily in mammals. (1/2535)Approximately 15 different alpha, or CXC, chemokines have thus far been isolated from 11 species of mammals. Among the best studied chemokines are the 12 human proteins that are encoded by 11 paralogous genes. In order to better understand the evolution and function of this group of genes, we isolated and characterized six novel GRO and GRO-related cDNA sequences from the cow (Bos taurus), the sheep (Ovis aries), the rabbit (Oryctolagus cuniculus), and the guinea pig (Cavia porcellus). The amino acid sequence of the diverged guinea pig GRO or KC gene is only 50%-60% similar to presumed orthologs from other species, while the sheep and cow GRO proteins are 90%-99% similar to each other. The presence of multiple GRO genes in the cow, the rabbit, and the sheep is consistent with what has been observed for humans. Phylogenetic analyses of amino acid sequences from 44 proteins indicate that genes orthologous to many of the 11 known from humans exist in other species. One such gene, interleukin 8, or IL8, has been isolated from nine species, including the rodent guinea pig; however, this gene is absent in the rat and the mouse, indicating a unique gene loss event in the rat/mouse (muroid rodent) lineage. The KC (or MIP2) gene of rodents appears to be orthologous to the GRO gene found in other taxonomic orders. Combined evidence from different sources suggests that IP10 and MIG share sister taxon relationships on the evolutionary tree, while the remaining paralogous genes represent independent lineages, with limited evidence for kinship between them. This observation indicates that these genes originated nearly contemporaneously via a series of gene duplication events. Relative-rate tests for synonymous and nonsynonymous nucleotide substitutions in the KC and IL8 genes did not detect rate heterogeneity; however, there are several notable features regarding the IL8 genes. For example, the IL8 proteins from two Old World monkeys are as similar to one another as they are to the IL8 protein from humans, and all observed nucleotide differences between the IL8 genes of the two monkeys cause amino acid changes; in other words, there are no synonymous differences between them.

Chemokine and chemokine receptor gene variants and risk of non-Hodgkin's lymphoma in human immunodeficiency virus-1-infected individuals. (2/2535)Normal B-lymphocyte maturation and proliferation are regulated by chemotactic cytokines (chemokines), and genetic polymorphisms in chemokines and chemokine receptors modify progression of human immunodeficiency virus-1 (HIV-1) infection. Therefore, 746 HIV-1-infected persons were examined for associations of previously described stromal cell-derived factor 1 (SDF-1) chemokine and CCR5 and CCR2 chemokine receptor gene variants with the risk of B-cell non-Hodgkin's lymphoma (NHL). The SDF1-3'A chemokine variant, which is carried by 37% of whites and 11% of blacks, was associated with approximate doubling of the NHL risk in heterozygotes and roughly a fourfold increase in homozygotes. After a median follow-up of 11.7 years, NHL developed in 6 (19%) of 30 SDF1-3'A/3'A homozygotes and 22 (10%) of 202 SDF1-+/3'A heterozygotes, compared with 24 (5%) of 514 wild-type subjects. The acquired immunodeficiency syndrome (AIDS)-protective chemokine receptor variant CCR5-triangle up32 was highly protective against NHL, whereas the AIDS-protective variant CCR2-64I had no significant effect. Racial differences in SDF1-3'A frequency may contribute to the lower risk of HIV-1-associated NHL in blacks compared with whites. SDF-1 genotyping of HIV-1-infected patients may identify subgroups warranting enhanced monitoring and targeted interventions to reduce the risk of NHL. (+info)
Cutting edge: clustered AU-rich elements are the target of IL-10-mediated mRNA destabilization in mouse macrophages. (3/2535)In the present study we show that IL-10-mediated inhibition of inflammatory gene expression can be mediated by an AU-rich element (ARE) cluster present in the 3' untranslated region (3'UTR) of sensitive genes. A series of chloramphenicol acetyl transferase (CAT) reporter gene constructs were prepared in which different fragments from the IL-10-sensitive KC mRNA 3'UTR were placed downstream of the coding region of the reporter gene CAT. CAT mRNA containing the KC 3'UTR was markedly destabilized as compared with the control CAT mRNA, and the decay rate was further increased in cells stimulated with IL-10. The KC 3'UTR contains an ARE cluster and three isolated ARE motifs. The ARE cluster spanning nucleotides 378-399 appeared to be both necessary and sufficient to mediate sensitivity to IL-10 because a 116-nucleotide fragment that contains the cluster conferred sensitivity, while mutation of the sequence between positions 378 and 399 eliminated sensitivity. The destabilizing effect of IL-10 was relatively selective, as the stability of chimeric CAT mRNAs was not modulated in cells treated with IFN-gamma or IL-4. (+info)
Identification of CXCR4 domains that support coreceptor and chemokine receptor functions. (4/2535)The interaction of the chemokine stromal cell-derived factor 1 (SDF-1) with its receptor CXCR4 is vital for cell trafficking during development, is capable of inhibiting human immunodeficiency virus type 1 (HIV-1) utilization of CXCR4 as a coreceptor, and has been implicated in delaying disease progression to AIDS in vivo. Because of the importance of this chemokine-chemokine receptor pair to both development and disease, we investigated the molecular basis of the interaction between CXCR4 and its ligands SDF-1 and HIV-1 envelope. Using CXCR4 chimeras and mutants, we determined that SDF-1 requires the CXCR4 amino terminus for binding and activates downstream signaling pathways by interacting with the second extracellular loop of CXCR4. SDF-1-mediated activation of CXCR4 required the Asp-Arg-Tyr motif in the second intracellular loop of CXCR4, was pertussis toxin sensitive, and did not require the distal C-terminal tail of CXCR4. Several CXCR4 mutants that were not capable of binding SDF-1 or signaling still supported HIV-1 infection, indicating that the ability of CXCR4 to function as a coreceptor is independent of its ability to signal. Direct binding studies using the X4 gp120s HXB, BH8, and MN demonstrated the ability of HIV-1 gp120 to bind directly and specifically to the chemokine receptor CXCR4 in a CD4-dependent manner, using a conformationally complex structure on CXCR4. Several CXCR4 variants that did not support binding of soluble gp120 could still function as viral coreceptors, indicating that detectable binding of monomeric gp120 is not always predictive of coreceptor function.

Expression of specific chemokines and chemokine receptors in the central nervous system of multiple sclerosis patients. (5/2535)Chemokines direct tissue invasion by specific leukocyte populations. Thus, chemokines may play a role in multiple sclerosis (MS), an idiopathic disorder in which the central nervous system (CNS) inflammatory reaction is largely restricted to mononuclear phagocytes and T cells. We asked whether specific chemokines were expressed in the CNS during acute demyelinating events by analyzing cerebrospinal fluid (CSF), whose composition reflects the CNS extracellular space. During MS attacks, we found elevated CSF levels of three chemokines that act toward T cells and mononuclear phagocytes: interferon-gamma-inducible protein of 10 kDa (IP-10); monokine induced by interferon-gamma (Mig); and regulated on activation, normal T-cell expressed and secreted (RANTES). We then investigated whether specific chemokine receptors were expressed by infiltrating cells in demyelinating MS brain lesions and in CSF. CXCR3, an IP-10/Mig receptor, was expressed on lymphocytic cells in virtually every perivascular inflammatory infiltrate in active MS lesions. CCR5, a RANTES receptor, was detected on lymphocytic cells, macrophages, and microglia in actively demyelinating MS brain lesions. Compared with circulating T cells, CSF T cells were significantly enriched for cells expressing CXCR3 or CCR5. Our results imply pathogenic roles for specific chemokine-chemokine receptor interactions in MS and suggest new molecular targets for therapeutic intervention. (+info)
The T cell-specific CXC chemokines IP-10, Mig, and I-TAC are expressed by activated human bronchial epithelial cells. (6/2535)Recruitment of activated T cells to mucosal surfaces, such as the airway epithelium, is important in host defense and for the development of inflammatory diseases at these sites. We therefore asked whether the CXC chemokines IFN-induced protein of 10 kDa (IP-10), monokine induced by IFN-gamma (Mig), and IFN-inducible T-cell alpha-chemoattractant (I-TAC), which specifically chemoattract activated T cells by signaling through the chemokine receptor CXCR3, were inducible in respiratory epithelial cells. The effects of proinflammatory cytokines, including IFN-gamma (Th1-type cytokine), Th2-type cytokines (IL-4, IL-10, and IL-13), and dexamethasone were studied in normal human bronchial epithelial cells (NHBEC) and in two human respiratory epithelial cell lines, A549 and BEAS-2B. We found that IFN-gamma, but not TNF-alpha or IL-1 beta, strongly induced IP-10, Mig, and I-TAC mRNA accumulation mainly in NHBEC and that TNF-alpha and IL-1 beta synergized with IFN-gamma induction in all three cell types. High levels of IP-10 protein (> 800 ng/ml) were detected in supernatants of IFN-gamma/TNF-alpha-stimulated NHBEC. Neither dexamethasone nor Th2 cytokines modulated IP-10, Mig, or I-TAC expression. Since IFN-gamma is up-regulated in tuberculosis (TB), using in situ hybridization we studied the expression of IP-10 in the airways of TB patients and found that IP-10 mRNA was expressed in the bronchial epithelium. In addition, IP-10-positive cells obtained by bronchoalveolar lavage were significantly increased in TB patients compared with normal controls. These results show that activated bronchial epithelium is an important source of IP-10, Mig, and I-TAC, which may, in pulmonary diseases such as TB (in which IFN-gamma is highly expressed) play an important role in the recruitment of activated T cells.

Isolation of the CXC chemokines ENA-78, GRO alpha and GRO gamma from tumor cells and leukocytes reveals NH2-terminal heterogeneity. Functional comparison of different natural isoforms. (7/2535)Chemokines are a family of chemotactic peptides affecting leukocyte migration during the inflammatory response. Post-translational modification of chemokines has been shown to affect their biological potency. Here, the isolation and identification of natural isoforms of the neutrophil chemoattractants GRO alpha and GRO gamma and the epithelial-cell-derived neutrophil attractant-78 (ENA-78), is reported. Cultured tumor cells produced predominantly intact chemokine forms, whereas peripheral blood monocytes secreted mainly NH2-terminally truncated forms. The order of neutrophil chemotactic potency of these CXC chemokines was GRO alpha > GRO gamma > ENA-78 both for intact and truncated forms. However, truncated GRO alpha (4,5,6-73), GRO gamma (5-73) and ENA-78(8,9-78) were 30-fold, fivefold and threefold more active than the corresponding intact chemokine. As a consequence, truncated GRO alpha (4,5,6-73) was 300-fold more potent than intact ENA-78 indicating that both the type of chemokine and its mode of processing determine the chemotactic potency. Similar observations were made when intact and truncated GRO alpha, GRO gamma and ENA-78 were compared for their capacity to induce an increase in the intracellular calcium concentration in neutrophilic granulocytes, and to desensitize the calcium response towards the CXC chemokine granulocyte chemotactic protein-2 (GCP-2). It must be concluded that physiological proteolytic cleavage of CXC chemokines in general enhances the inflammatory response, whereas for CC chemokines NH2-terminal processing mostly results in reduced chemotactic potency.

Elevated constitutive IkappaB kinase activity and IkappaB-alpha phosphorylation in Hs294T melanoma cells lead to increased basal MGSA/GRO-alpha transcription. (8/2535)The basal transcription of the CXC chemokine, melanocyte growth stimulatory activity (MGSA)/growth-regulated protein (GRO)-alpha, is up-regulated in Hs294T melanoma cells compared with the normal retinal pigment epithelial (RPE) cells. Previous studies characterized a cytokine-inducible, functional nuclear factor (NF)-kappaB consensus element in the immediate 5' regulatory region of the MGSA/GRO-alpha gene at -78 bp. Although the cytokine-inducible mechanisms for transcription of this gene are fairly well delineated, the mechanisms involved in its basal up-regulation of transcription in Hs294T melanoma cells are poorly understood. Recently, we demonstrated an increased rate of IkappaB-alpha degradation in Hs294T cells, which leads to an increased nuclear localization of NF-kappaB (R. L. Shattuck-Brandt and A. Richmond. Cancer Res., 57: 3032-3039, 1997). Here we demonstrate that Hs294T melanoma cells have elevated basal IkappaB kinase (IKK) activity relative to RPE cells, causing an increased constitutive IkappaB-alpha phosphorylation and degradation. We also show here that the resultant elevated nuclear NF-kappaB (p50/p65) in these cells is responsible for the increased basal transcription of MGSA/GRO-alpha. Pretreatment of Hs294T or RPE cells with proteasome inhibitors MG115 or MG132 captures the slower migrating, constitutively phosphorylated form of IkappaB-alpha in Hs294T melanoma cells, but not in RPE cells. In addition, a phospho-specific antibody that specifically recognizes the inhibitory form of IkappaB that is phosphorylated at Ser-32 reacted with IkappaB-alpha in Hs294T cell, but not in unstimulated RPE cells. Although the basal level of protein expression of IKK-alpha or IKK-beta are the same in both Hs294T and RPE cells, immunoprecipitation with IKK-alpha antibody combined with activity assay reveal a constitutively active IKK complex in Hs294T melanoma cells. Cotransfection of a 350-bp MGSA/GRO-alpha promoter-luciferase reporter construct with either the dominant negative IKK-alpha or the repressors of NF-kappaB, the IkappaB-alpha wild type or mutants lacking the inducible phosphorylation sites, demonstrates that the increased basal MGSA/GRO-alpha transcription in the Hs294T cells is due to the enhanced nuclear activation of NF-kappaB.

The proinflammatory CXC-chemokines GRO-α/CXCL1 and MIG/CXCL9 are concomitantly expressed in ulcerative colitis and decrease...
Background Ulcerative colitis is characterized by relapsing mucosal inflammation where the lesions include tissue-damaging granulocytes. In addition, T cells and natural killer (NK) cells play important pathophysiologic roles. Chemokines are a large family of peptides that play key roles in the regulation of inflammation. The CXC-chemokines, growth-related oncogene (GRO)-α/CXCL1 and interleukin (IL)-8/CXCL8, both recruit neutrophils and possess mitogenic properties, whereas the interferon-dependent CXC-chemokines monokine induced by gamma-interferon (MIG)/CXCL9, interferon-γ inducible protein of 10 kD/CXCL10, and IFN-inducible T cell alpha chemoattractant/CXCL11 recruit and activate T cells and NK cells. Materials and methods The expression of CXC-chemokines was studied in eight controls and in 11 patients suffering from ulcerative colitis in the distal part of the colon, before and during topical treatment with corticosteroids. Perfusates (obtained before, after 7 days, and after 28 days of ...
CXC chemokine receptors - Wikipedia
CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. They represent one subfamily of chemokine receptors, a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times. There are currently seven known CXC chemokine receptors in mammals, named CXCR1 through CXCR7. CXCR1 and CXCR2 are closely related receptors that recognize CXC chemokines that possess an E-L-R amino acid motif immediately adjacent to their CXC motif. CXCL8 (otherwise known as interleukin-8) and CXCL6 can both bind CXCR1 in humans, while all other ELR-positive chemokines, such as CXCL1 to CXCL7 bind only CXCR2. They are both expressed on the surface of neutrophils in mammals. CXCR3 is expressed predominantly on T cells (T lymphocytes), and also on other lymphocytes [some B cells (B lymphocytes) and NK cells] and is highly induced following cell activation. There are two ...
IL‑17A promotes CXCR2‑dependent angiogenesis in a mouse model of liver cancer
In the present study, it was demonstrated that IL-17A could stimulate the secretion of angiogenic CXC chemokines from liver cancer cells, which may recruit endothelial cells to the tumor cells in a CXCR2-dependent manner. Tumor angiogenesis was also promoted by IL-17A expression in vivo. The CXC chemokines can be classified as angiogenic or angiostatic predominantly based on the presence or absence of an ELR motif. The angiogenic CXC chemokines include CXCL1, CXCL2, CXCL3, CXCL5, CXCL6, CXCL8 and CXCL12, and the angiostatic chemokines include CXCL4, CXCL9, CXCL10, CXCL11 and CXCL14 (21). IL-17A was shown to increase the expression of CXCL1, CXCL2, CXCL3, CXCL5, CXCL6 and CXCL8 in Huh7.5 cells and upregulated CXCL2 in HepG2 cells. Additionally, angiostatic CXC chemokines were not affected by IL-17A in both cell lines. IL-17A has been reported to stimulate VEGFA production and promote angiogenesis in several cancer cell lines (16-18) and it has been shown previously that IL-17A does not affect ...
Assay Solution. Human CXCL9/MIG ELISA Kit
Chemokine (C-X-C motif) ligand 9 (CXCL9) is a small cytokine belonging to the CXC chemokine family that is also known as Monokine induced by gamma interferon (MIG). CXCL9 is a T-cell chemoattractant, which is induced by IFN-γ. It is closely related to two other CXC chemokines called CXCL10 and CXCL11, whose genes are located near the gene for CXCL9 on human chromosome 4. CXCL9, CXCL10 and CXCL11 all elicit their chemotactic functions by interacting with the chemokine receptor CXCR3. Neutrophil collagenase/matrix metalloproteinase 8 (MMP-8) degrades CXCL9 and cleaves CXCL10 at two positions. Gelatinase B/matrix metalloproteinase 9 (MMP-9) degrades CXCL10 and cleaves CXCL9 at three different sites in its extended carboxy-terminal region ...

Induction of the chemokine stromal-derived factor-1 following DNA damage improves human stem cell function
The chemokine stromal-derived factor-1 (SDF-1) controls many aspects of stem cell function. Details of its regulation and sites of production are currently unknown. We report that in the bone marrow, SDF-1 is produced mainly by immature osteoblasts and endothelial cells. Conditioning with DNA-damagi …

Transmembrane signaling of the CXC chemokine stromal cell-derived factor-1 (SDF-1) is mediated by CXCR4, a G protein-coupled receptor initially identified in leukocytes and shown to serve as a coreceptor for the entry of HIV into lymphocytes. Characterization of SDF-1- and CXCR4-deficient mice has revealed that SDF-1 and CXCR4 are of vital developmental importance. To study the role of the SDF-1/CXCR4-chemokine/receptor system as a regulator of vertebrate development, we isolated and characterized a cDNA encoding SDF-1 of the lower vertebrate Xenopus laevis (xSDF-1). Recombinant xSDF-1 was produced in insect cells, purified, and functionally characterized. Although xSDF-1 is only 64-66% identical with its mammalian counterparts, it is indistinguishable from human (h)SDF-1alpha in terms of activating both X. laevis CXCR4 and hCXCR4. Thus, both xSDF-1 and hSDF-1alpha promoted CXCR4-mediated activation of heterotrimeric G(i2) in a cell-free system and induced release of intracellular calcium ions ...

Combined effects of IL-8 and CXCR2gene polymorphisms on breast cancer susceptibility and aggressiveness | BMC Cancer | Full Text
The ELR+ CXC chemokines play an important role in tumor growth and progression in a number of tumor model systems. IL-8/CXCL8 was the first described angiogenic, mitogenic, and motogenic chemokine in various cancer models and is the prototype of ELR+ CXC chemokines [8, 10-13]. This chemokine was initially discovered on the basis of its ability to induce mobilization of neutrophils and lymphocytes in vivo . Like the basic fibroblast growth factor (bFGF) and the vascular endothelial growth factor (VEGF), it is a strong angiogenesis inducer. IL-8 mediates endothelial cell chemotaxis and proliferation in vitro and in vivo .. The fact that all ELR+CXC chemokines mediate angiogenesis highlights the importance of identifying a common receptor that mediates their biological functions in promoting angiogenesis. The candidate CXC chemokine receptors are CXCR1 and CXCR2. Only CXCL-8/IL-8 and CXCL-6 specifically bind to CXCR1 whereas all ELR+CXC chemokines bind to CXCR2. There is evidence that CXCR2 ...
ENA-78 Rabbit Polyclonal Antibody - Western Blot Antibodies - Bioworld Consulting Laboratories, LLC.
Description: Description of target: C-X-C motif chemokine 5 is a protein that in humans encoded by the CXCL5 gene. The protein encoded by this gene, CXCL5 is a small cytokine belonging to the CXC chemokine family that is also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78). It is produced following stimulation of cells with the inflammatory cytokines interleukin-1or tumor necrosis factor-alpha. Expression of CXCL5 has also been observed in eosinophils, and can be inhibited with the type II interferon IFN-gamma. This chemokine stimulates the chemotaxis of neutrophils possessing angiogenic properties. It elicits these effects by interacting with the cell surface chemokine receptor CXCR2. The gene for CXCL5 is encoded on four exons and is located on humanchromosome 4 amongst several other CXC chemokine genes. CXCL5 has been implicated in connective tissue remodeling. CXCL5 plays a role in reducing sensitivity to sunburn pain in some subjects, and is a potential target which ...
CXCL10 - Wikipedia
C-X-C motif chemokine 10 (CXCL10) also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10 is an 8.7 kDa protein that in humans is encoded by the CXCL10 gene. C-X-C motif chemokine 10 is a small cytokine belonging to the CXC chemokine family. The gene for CXCL10 is located on human chromosome 4 in a cluster among several other CXC chemokines. CXCL10 is secreted by several cell types in response to IFN-γ. These cell types include monocytes, endothelial cells and fibroblasts. CXCL10 has been attributed to several roles, such as chemoattraction for monocytes/macrophages, T cells, NK cells, and dendritic cells, promotion of T cell adhesion to endothelial cells, antitumor activity, and inhibition of bone marrow colony formation and angiogenesis. This chemokine elicits its effects by binding to the cell surface chemokine receptor CXCR3. The three-dimensional crystal structure of this chemokine has been determined under 3 different conditions to a resolution of up to ...

Chemokines are a large group of chemotactic cytokines that play an important pathogenic role in inflammatory diseases and autoimmune disorders by enhancement of leukocyte recruitment and activation at inflammatory sites [3-6]. ENA-78 is a CXC chemokine that attracts neutrophils during inflammation .. In this work, serum levels of ENA-78 were significantly higher in autistic children than healthy control children (P , 0.001). In addition, 69.35% of autistic children had increased serum levels of ENA-78. This study was the first to investigate serum levels of ENA-78 in autistic children. ENA-78 is an inflammatory C-X-C chemokine that is encoded by the CXCL5 gene . Its levels are elevated in myriad inflammatory conditions [29-32].. ENA-78 is an α chemokine which is produced concomitantly with IL-8 and melanoma growth stimulating activity . The main stimuli for secretion of chemokines, including ENA-78, are the early signals elicited during innate immune response such as bacterial ...

IP-10 has been detected in the CSF and brain parenchyma of patients with a variety of neuroinflammatory diseases (15, 26, 43, 44) and is a potent chemoattractant for activated T lymphocytes and NK cells (11). In EAE, an animal model for MS, IP-10 levels in the CNS have been correlated with the development of clinical disease and the recruitment of CXCR3-expressing pathogenic T cells (19, 20, 45). Treatment of SJL mice with Abs to IP-10 before adoptive transfer of encephalitogenic T cells or immunizing mice with naked IP-10 DNA decreased the severity of EAE (29). Based on these observations, IP-10 is thought to be essential for the development of CNS mononuclear infiltrates, and its receptor CXCR3, is considered a putative therapeutic target for diseases involving the trafficking of inflammatory T cells. However, the absolute requirement for IP-10 in EAE has never been directly examined.. In this study, we sought to determine whether IP-10 is required for the development of EAE by analyzing ...
Product Detail｜Immuno-Biological Laboratories Co,Ltd.｜IBL
GRO (Growth Related Oncogene) belonging to IL-8 family is polypeptide which has three isoforms α, β and γ, and it inhibits proliferation of endothelial cells. GRO/CINC-1 (cytokine-induced neutrophil chemo attractant 1) was originally purified from media conditioned by IL-1β stimulated rat kidney epithelioid cells (NRK-52E.) Amino acid sequence that encodes rat CINC-1 was identified in 1989 by Watanabes group at Toyama Medical and Pharmaceutical University. CINC-1 is a member of the alpha (CXC) subfamily of chemokines. Three additional rat CXC chemokines (CINC-2α, CINC-2β, CINC-3/MIP-2) have been identified. The protein sequence of CINC-1 is 63 - 67% identical to that of CINC-2α, CINC-2β and CINC-3/MIP-2. In addition, each of GROα, GROβ and GROγ is sharing 68%, 71% and 69% identity with CINC-1. This has been suggested that CINCs are the rat counterparts of human GROs. GROα/MGSA has a high homology with IL-8 in amino acid sequences. It has been reported that it also has a similar ...

TY - JOUR. T1 - Chemokines in ischemia and reperfusion. AU - Frangogiannis, Nikolaos G.. PY - 2007/5. Y1 - 2007/5. N2 - Chemokine signaling plays an important role in the post-ischemic inflammatory response. Overlapping pathways involving reactive oxygen intermediates, Toll-like receptor (TLR) activation, the complement cascade and the nuclear factor (NF)-κB system induce both CXC and CC chemokines in ischemic tissues. Reperfusion accentuates chemokine expression promoting an intense inflammatory reaction. ELR-containing CXC chemokines regulate neutrophil infiltration in the ischemic area, whereas CXCR3 ligands may mediate recruitment of ThI cells. CC chemokines, on the other hand, induce mononuclear cell infiltration and macrophage activation. Evidence suggests that chemokine signaling mediates actions beyond leukocyte chemotaxis and activation, regulating angiogenesis and fibrous tissue deposition. Effective repair of ischemic tissue is dependent on a well-orchestrated cellular response and ...

There are many different functions of CXCL1 and other members of the CXC family. As previously stated, this cytokine works to help the spinal cord develop properly. This is done because it prevents and slows down the movement in oligodendrocyte precursors. Along with this, CXCL1 also helps with the production and formation of new blood cells from pre-existing ones. This process is described as angiogenesis.

Permalien vers Differential signalling of the chemokine receptor CXCR4 by stromal cell-derived factor 1 and the HIV...
CXCR4 is the Gi protein-linked seven-transmembrane receptor for the alpha chemokine stromal cell-derived factor 1 (SDF-1), a chemoattractant for lymphocytes. This receptor is highly conserved between human and rodent. CXCR4 is also a coreceptor for entry of human immunodeficiency virus (HIV) in T cells and is expressed in the CNS. To investigate how these CXCR4 ligands influence CNS development and/or function, we have examined the expression and signalling of this chemokine receptor in rat neurons and astrocytes in vitro. CXCR4 transcripts and protein are synthesized by both cell types and in E15 brain neuronal progenitors. In these progenitors, SDF-1, but not gp120 (the HIV glycoprotein), induced activation of extracellular signal regulated kinases (ERKs) 1/2 and a dose-dependent chemotactic response. This chemotaxis was inhibited by Pertussis toxin, which uncouples Gi proteins and the bicyclam AMD3100, a highly selective CXCR4 antagonist, as well as by an inhibitor of the MAP kinase pathway. In

TY - JOUR. T1 - Differential regulation of the expression of cytokine-induced neutrophil chemoattractant by mouse macrophages. AU - Crippen, Tawni L.. AU - Riches, David W H. AU - Hyde, Dallas M.. PY - 1998. Y1 - 1998. N2 - The production of cytokine-induced neutrophil chemoattractant (CINC) by functionally diverse mouse bone-marrow-derived macrophages was determined. Studies showed that β1,3-glucan, IL-1β, TNFα and IFNγ/TNFα induced expression and production of CINC in macrophages while neither IFNγ nor TGFβ alone induced detectable CINC expression. Pretreatment or simultaneous treatment of macrophages with TGFβ resulted in suppression of CINC protein production. These studies demonstrate that IFNγ and TNFα, found early during the inflammatory response, induce production of CINC, as well as induce macrophages into a cytocidal state that are capable of killing transformed cells, parasites and bacteria, and recruiting neutrophils. In contrast, TGFβ, found during reparative stages of ...

SNU Open Repository and Archive: Differential expression and polarized secretion of CXC and CC chemokines by human intestinal...
Intestinal epithelial cells are the initial sites of host response to Clostridium difficile infection and can play a role in signaling the influx of inflammatory cells. To further explore this role, the regulated expression and polarized secretion of CXC and CC chemokines by human intestinal epithelial cells were investigated. An expression of the CXC chemokines, including IL-8 and growth-related oncogene (GRO)-alpha, and the CC chemokine monocyte chemoattractant protein (MCP)-1 from HT-29 cells increased in the 1-6 hr following C. difficile toxin A stimulation, assessed by quantitative RT-PCR. In contrast, the expression of neutrophil activating protein-78 (ENA-78) was delayed for 18 hr. The up-regulated mRNA expression of chemokines was paralleled by the increase of protein levels. However, the expression of macrophage inflammatory protein (MIP)-1alpha, RANTES (regulated on activation normal T cells expressed and secreted), and interferon-gamma-inducible protein-10 (IP-10) was not changed in ...
Bone-derived SDF-1 stimulates IL-6 release via CXCR4, ERK and NF-κB pathways and promotes osteoclastogenesis in human oral...
Oral squamous cell carcinoma (SCC) has a striking tendency to invade to bone. The chemokine stromal cell-derived factor-1 (SDF-1) is constitutively secreted by osteoblasts and plays a key role in homing of hematopoietic cells to the bone marrow. Interleukin (IL)-6 plays an important role in osteoclastogenesis. Herein, we found that SDF-1α increased the secretion of IL-6 in cultured human SCC cells, as shown by reverse transcriptase-polymerase chain reaction and enzyme-linked immunosorbent assay. SDF-1α also increased the surface expression of chemokine receptor 4 (CXCR4) in SCC cells. CXCR4-neutralizing antibody, CXCR4-specific inhibitor (AMD3100) or small interfering RNA against CXCR4 inhibited SDF-1α-induced increase IL-6 production. The transcriptional regulation of IL-6 by SDF-1α was mediated by phosphorylation of extracellular signal-regulated kinases (ERKs) and activation of the nuclear factor-kappa B (NF-κB) components p65 and p50. The binding of p65 and p50 to the NF-κB element on ...
Circulating progenitor cells
Particular populations of stem cells in the bone marrow harbors the membrane receptor CXCR4 which is a specific receptor for chemokine stromal cell-derived factor (SDF-1). In addition, the presence of CXCR4 identifies cells showing expression of early cardiac, muscle and endothelial markers. In mice experiments it was shown that bone marrow contains pools of cells that express early cardiac lineage markers (Nkx2.5/Csx, GATA-4, and MEF2C) and the population can be mobilised by inducing the myocardial infarction. This is the first proof that postnatal bone marrow contains nonhematopoietic population of cells that express markers for cardiac differentiation [4-6]. The peak expression of cardiac markers was found at the same time as most significant increase of stem cells number was measured . A Similar phenomenon seems to occur in humans in the setting of AMI . The SDF-1/CXCR-4 axis seems particularly important in stem/progenitor cell homing, chemotaxis, engrafment and retention in ...

Relatively little is known about the biological significance or cellular target of ELR+ CXC chemokines in the development and/or maintenance of autoimmune demyelinating disease, in which infiltrates are dominated by lymphocytes and monocytes. Although PMN have been detected entering the CNS during the preclinical phase of EAE (17), their relative paucity in mature EAE and MS lesions has led some investigators to question their importance (8). With regard to more populous myeloid subsets in EAE and MS lesions, activated macrophages are recruited to the CNS by a CCL2-dependent pathway across several EAE models (18). Perhaps because of such observations, the role of ELR+ CXC chemokines in the pathophysiology of autoimmune demyelination has not been previously investigated in depth. However, a growing body of data indicates that they merit attention. For example, IL-17, a potent inducer of ELR+ CXC chemokines, was recently implicated in the pathogenesis of both EAE and MS (19-21). In addition, ...

CXCL6 - wikidoc
Chemokine (C-X-C motif) ligand 6 (CXCL6) is a small cytokine belonging to the CXC chemokine family that is also known as granulocyte chemotactic protein 2 (GCP-2). As its former name suggests, CXCL6 is a chemoattractant for neutrophilic granulocytes. It elicits its chemotactic effects by interacting with the chemokine receptors CXCR1 and CXCR2. The gene for CXCL6 is located on human chromosome 4 in a cluster with other CXC chemokine genes. ...

Who Stole the Chemokine? | Science Signaling
Primordial germ cells (PGCs) in the zebrafish embryo face a long migration from the point at which they are specified during development to the location of the future gonad, and it takes some precise signaling to get them there. Major guidance cues are provided by the chemokine SDF-1a (stromal-derived factor-1 alpha), which attracts the PGCs by signaling through its receptor CXCR4b [chemokine (C-X-C motif) receptor 4b]. SDF-1a also binds to another receptor, CXCR7, but the function of this receptor in PGC cell migration has been uncertain. Boldajipour et al.s experiments indicate that CXCR7s function is not to signal but rather to act as a sink that soaks up stray molecules of SDF-1a, thus adding to the precision of SDF-1a signaling through CXCR4b. Transplantation experiments taking PGCs from animals lacking CXCR7 into wild-type embryos showed that the critical function of CXCR7 was in somatic cells, not the PGCs. Microscopy of fluorescently tagged proteins showed that CXCR7 promoted ...
Objective To assess whether serum levels of CC and CXC chemokines correlate with disease activity in patients with rheumatoid arthritis (RA), and to determine whether these effects predict clinical response. Methods Serum levels of the chemokines CC (CCL2, CCL5) and CXC (CXCL8, CXCL9, CXCL10) were quantified at baseline and after 12 weeks of treatment with disease-modifying antirheumatic drugs or biologic agents in 28 patients using flow cytometry. Serum from 40 healthy individuals was collected for comparison at baseline. Response to treatment was classified according to the European League Against Rheumatism (EULAR) response criteria. Remission of disease was defined as a Disease Activity Score , 2.6. Results The baseline serum concentrations of CC and CXC chemokines were significantly elevated in patients with active RA compared to healthy controls (p , 0.05) except for CCL2. Significant improvement in all disease activity measurements was observed after 12 weeks of treatment. Seventeen ...
5098 CXCL-8, a member of the CXC chemokine family, is constitutively expressed in malignant melanoma and functions as an autocrine/paracrine growth, invasive and angiogenic factor. Two high affinity receptors of CXCL-8, CXCR1 and CXCR2, are differentially expressed on melanoma cells as well as on endothelial cells. We have demonstrated that CXCR1 is constitutively expressed in all the melanoma cases irrespective of stage and grade, however, CXCR2 expression is restricted to aggressive melanoma tumors, with higher metastatic potential. The precise functional role of these receptors in melanoma growth and angiogenesis remains unclear. To gain insight into their functional role, we stably overexpressed CXCR1 or CXCR2 in A375P (tumorigenic, low metastatic) and A375SM (tumorigenic and highly metastatic) melanoma cells. Cells over-expressing CXCR1 or CXCR2 exhibited significant increase in CXCL-8-mediated proliferation and survival as compared to control (vector-transfected) cells. Moreover, we ...
CX3CL1 - wikidoc
Fractalkine is a large cytokine protein of 373 amino acids, it contains multiple domains and is the only known member of the CX3C chemokine family. It is also commonly known under the names fractalkine (in humans) and neurotactin (in mice). The polypeptide structure of CX3CL1 differs from the typical structure of other chemokines. For example, the spacing of the characteristic N-terminal cysteines differs; there are three amino acids separating the initial pair of cysteines in CX3CL1, with none in CC chemokines and only one intervening amino acid in CXC chemokines. CX3CL1 is produced as a long protein (with 373-amino acid in humans) with an extended mucin-like stalk and a chemokine domain on top. The mucin-like stalk permits it to bind to the surface of certain cells. However a soluble (90 kD) version of this chemokine has also been observed. Soluble CX3CL1 potently chemoattracts T cells and monocytes, while the cell-bound chemokine promotes strong adhesion of leukocytes to activated ...

Natural post-translational modifications of chemokines | Biochemical Society Transactions
Chemokines, adhesion molecules, cytokines and proteases regulate the extravasation of leucocytes during acute and chronic inflammation and leucocyte homing. Chemokines are produced after transcriptional activation by inflammatory mediators such as cytokines or microbial Toll-like receptor ligands and their effect depends on the expression of chemokine receptors on specific cell types. More and more evidence points towards a role for post-translational modifications in the fine-tuning of chemokine activity. Although both glycosylation and proteolytic processing of the C- and/or N-terminus of chemokines has been reported, mainly proteolytic processing of the N-terminus appears to affect the receptor specificity, chemotactic property and signalling potency of these low-molecular-mass proteins. N-terminal processing of chemokines by aminopeptidases or endoproteases may alter the receptor specificity and may result in up- or down-regulation of their chemotactic, antiviral or angiogenic activity. ...
Exbio antibodies - Mouse Monoclonal to CD184 / CXCR4 12G5 (IgG2a)
CD184, also known as CXCR4 or fusin, is a receptor for the C-X-C chemokine SDF-1. It is expressed mainly in hematopoietic cells, vascular endothelium, and neural tissue. CD184 is a G-protein coupled receptor containing extracellular N-terminal, seven transmembrane domains and intracellular C-terminal domain. It transduces signal by increasing the intracellular calcium level. CD184 plays an essential role in vascularization of the gastrointestinal tract, and is involved in cerebellar development and in hematopoiesis. It is also a coreceptor (with CD4) for HIV-1 X4 virus and a primary receptor for some HIV-2 isolates ...
The experiments described in this study suggest that the chemokine SDF-1 acts as a neurotransmitter in the DG. The evidence supporting this supposition is similar to that available for GABA, certainly a well-established neurotransmitter. Thus, both GABA and SDF-1 are localized in synaptic vesicles within DG nerve terminals. Both GABA and SDF-1 produce similar electrophysiological effects on nestin-EGFP and DCX-EGFP-expressing cells in the SGZ. Moreover, it appears that both GABA and SDF-1 are tonically released in the DG. Thus, addition of both GABAA and CXCR4 receptor blockers elicited an outward current, suggesting that GABA and SDF-1 normally exert a tonic influence on type 2 progenitor cells. It also appears that the effects of GABA and SDF-1 are linked in some way because the observed effects of SDF-1 are sensitive to both GABAA and CXCR4 blockers.. SDF-1 and its receptor CXCR4 have been shown to be widely expressed throughout the developing and adult nervous systems (Stumm et al., 2002; ...

Mariagrazia Uguccioni | Humanitas University
The research interest of my group remains focused on Chemokine activities in physiology and pathology, with an emphasis on the mechanisms governing fine-tuning modulation of their expression and activity. Chemokines are secreted proteins and have emerged as key controllers of integrin function and cell locomotion. The effects of chemokines are mediated by seven transmembrane domain receptors coupled to GTP-binding proteins, which are differentially expressed in a wide range of cell types. The resulting combinatorial diversity in responsiveness to chemokines guarantees the proper tissue distribution of distinct leukocyte subsets under normal and inflammatory/pathological conditions. A vast range of in situ experiments, aimed at understanding which chemokines are produced in specific circumstances, has revealed that a variety of chemokines can be concomitantly produced at target sites of leukocyte trafficking and homing. This renders the chemokine system a good target for therapy, and has ...

Asthma affects almost 20 million people in the United States and more than 300 million people worldwide. Of these, 10-15% have severe asthma, which is refractory to commonly available drugs. New drugs are needed because those that are currently available cannot control symptoms and exacerbations in all patients and can cause adverse reactions. In the past 10 years, there have been substantial advances in the understanding of asthma genetics, airway biology, and immune cell signaling. These advances have led to the development of small molecule therapeutics and biologic agents that may improve asthma care in the future. Several new classes of asthma drugs-including ultra long acting β agonists and modulators of the interleukin 4 (IL-4), IL-5, IL-13, and IL-17 pathways-have been evaluated in randomized controlled trials. Other new drug classes-including dissociated corticosteroids, CXC chemokine receptor 2 antagonists, toll-like receptor 9 agonists, and tyrosine kinase inhibitors-remain in ...

This receptor is expressed by activated, but not by resting, T and B cells. TRAF2 and TRAF5 can interact with this receptor, and mediate the signal transduction that leads to the activation of NF-kappaB. It is a positive regulator of apoptosis, and also has been shown to limit the proliferative potential of autoreactive CD8 effector T cells and protect the body against autoimmunity. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. ...

Activation of various innate immune signaling pathways (TLR3, TLR4, TLR7, TLR8, TLR9, cGAS, RIG-I, MDA-5) leads to the rapid induction of type I IFNs due to their (mostly) intronless gene structure. The regulatory elements upstream of type I IFN genes differ, allowing differential transcription of type I IFNs in response to stimuli. In particular, IFNβ contains a κB regulatory site, whereas IFNα subtypes do not. Production of specific type I IFNs is usually limited to a small number of type I IFN subtypes. Once secreted, type I IFNs signal through IFNAR in a paracrine and autocrine manner. IFNAR is a heteromeric cell surface receptor composed of two subunits, referred to as the low affinity subunit, IFNAR1, and the high affinity subunit, IFNAR2. Upon binding of type I interferons, IFNAR activates the JAK-STAT signalling pathway, along with MAPK, PI3K, and Akt signaling pathways. IFNAR agonism results in transcriptional changes, with the potential to increase or ...

Interleukin-1 receptor-like 2 is a protein that in humans is encoded by the IL1RL2 gene. The protein encoded by this gene is a member of the interleukin 1 receptor family. An experiment with transient gene expression demonstrated that this receptor was incapable of binding to interleukin 1 alpha and interleukin 1 beta with high affinity. This gene and four other interleukin 1 receptor family genes, including interleukin 1 receptor, type I (IL1R1), interleukin 1 receptor, type II (IL1R2), interleukin 1 receptor-like 1 (IL1RL1), and interleukin 18 receptor 1 (IL18R1), form a cytokine receptor gene cluster in a region mapped to chromosome 2q12. ...
Growth hormone receptor
... is a protein that in humans is encoded by the GHR gene. GHR orthologs  have been identified in most mammals.. This gene encodes a protein that is a transmembrane receptor for growth hormone. Binding of growth hormone to the receptor leads to receptor dimerization (the receptor may however also exist as a pre-assembled non-functional dimer ) and the activation of an intra- and intercellular signal transduction pathway leading to growth. A common alternate allele of this gene, called GHRd3, lacks exon three and has been well-characterized. Mutations in this gene have been associated with Laron syndrome, also known as the growth hormone insensitivity syndrome (GHIS), a disorder characterized by short stature (proportional dwarfism). Other splice variants, including one encoding a soluble form of the protein (GHRtr), have been observed but have not been thoroughly characterized. Laron mice (that is mice genetically engineered to carry defective Ghr), have a ...

- CXC chemokine receptors are integral membrane proteins that specifically bind and respond to cytokines of the CXC chemokine family. (wikipedia.org)
- They represent one subfamily of chemokine receptors, a large family of G protein-linked receptors that are known as seven transmembrane (7-TM) proteins, since they span the cell membrane seven times. (wikipedia.org)
- There are currently six known CXC chemokine receptors in mammals, named CXCR1 through CXCR6. (wikipedia.org)
- CXCR1 and CXCR2 are closely related receptors that recognize CXC chemokines that possess an E-L-R amino acid motif immediately adjacent to their CXC motif. (wikipedia.org)
