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.
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.
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.
Interleukin 1 Receptor Antagonist Protein
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.
Receptors present on activated T-LYMPHOCYTES and B-LYMPHOCYTES that are specific for INTERLEUKIN-2 and play an important role in LYMPHOCYTE ACTIVATION. They are heterotrimeric proteins consisting of the INTERLEUKIN-2 RECEPTOR ALPHA SUBUNIT, the INTERLEUKIN-2 RECEPTOR BETA SUBUNIT, and the INTERLEUKIN RECEPTOR COMMON GAMMA-CHAIN.
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.
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.
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.
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.
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.
Cell surface receptors that are specific for INTERLEUKIN-1. Included under this heading are signaling receptors, non-signaling receptors and accessory proteins required for receptor signaling. Signaling from interleukin-1 receptors occurs via interaction with SIGNAL TRANSDUCING ADAPTOR PROTEINS such as MYELOID DIFFERENTIATION FACTOR 88.
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)
Receptors present on a wide variety of hematopoietic and non-hematopoietic cell types that are specific for INTERLEUKIN-4. They are involved in signaling a variety of immunological responses related to allergic INFLAMMATION including the differentiation of TH2 CELLS and the regulation of IMMUNOGLOBULIN E production. Two subtypes of receptors exist and are referred to as the TYPE I INTERLEUKIN-4 RECEPTOR and the TYPE II INTERLEUKIN-4 RECEPTOR. Each receptor subtype is defined by its unique subunit composition.
A lymphohematopoietic cytokine that plays a role in regulating the proliferation of ERYTHROID PRECURSOR CELLS. It induces maturation of MEGAKARYOCYTES which results in increased production of BLOOD PLATELETS. Interleukin-11 was also initially described as an inhibitor of ADIPOGENESIS of cultured preadipocytes.
Gene Expression Regulation
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.
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.
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.
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.
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.

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.
Tumor Cells, Cultured
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.
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.
Interleukin-13 Receptor alpha1 Subunit
An interleukin receptor subunit with specificity for INTERLEUKIN-13. It dimerizes with the INTERLEUKIN-4 RECEPTOR ALPHA SUBUNIT to form the TYPE II INTERLEUKIN-4 RECEPTOR which has specificity for both INTERLEUKIN-4 and INTERLEUKIN-13. Signaling of this receptor subunit occurs through the interaction of its cytoplasmic domain with JANUS KINASES such as the TYK2 KINASE.
Reverse Transcriptase Polymerase Chain Reaction
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.
Subpopulation of CD4+ lymphocytes that cooperate with other lymphocytes (either T or B) to initiate a variety of immune functions. For example, helper-inducer T-cells cooperate with B-cells to produce antibodies to thymus-dependent antigens and with other subpopulations of T-cells to initiate a variety of cell-mediated immune functions.
Dose-Response Relationship, Drug
STAT3 Transcription Factor
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.

They are INTERLEUKIN-2-activated NK cells that have no MAJOR HISTOCOMPATIBILITY COMPLEX restriction or need for antigen stimulation. LAK cells are used for ADOPTIVE IMMUNOTHERAPY in cancer patients.
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).
Disease Models, Animal
Complex of at least five membrane-bound polypeptides in mature T-lymphocytes that are non-covalently associated with one another and with the T-cell receptor (RECEPTORS, ANTIGEN, T-CELL). The CD3 complex includes the gamma, delta, epsilon, zeta, and eta chains (subunits). When antigen binds to the T-cell receptor, the CD3 complex transduces the activating signals to the cytoplasm of the T-cell. The CD3 gamma and delta chains (subunits) are separate from and not related to the gamma/delta chains of the T-cell receptor (RECEPTORS, ANTIGEN, T-CELL, GAMMA-DELTA).
Receptors, Interleukin-1 Type I
An interleukin-1 receptor subtype that is involved in signaling cellular responses to INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The binding of this receptor to its ligand causes its favorable interaction with INTERLEUKIN-1 RECEPTOR ACCESSORY PROTEIN and the formation of an activated receptor complex.
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.

Cell surface receptors that are specific for INTERLEUKIN-5. They are heterodimeric proteins consisting of the INTERLEUKIN-5 RECEPTOR ALPHA SUBUNIT and the CYTOKINE RECEPTOR COMMON BETA SUBUNIT. Signaling from interleukin-5 receptors can occur through interaction of their cytoplasmic domains with SYNTENINS.
A long pro-domain caspase that has specificity for the precursor form of INTERLEUKIN-1BETA. It plays a role in INFLAMMATION by catalytically converting the inactive forms of CYTOKINES such as interleukin-1beta to their active, secreted form. Caspase 1 is referred as interleukin-1beta converting enzyme and is frequently abbreviated ICE.
STAT6 Transcription Factor
High affinity receptors for INTERLEUKIN-3. They are found on early HEMATOPOIETIC PROGENITOR CELLS; progenitors of MYELOID CELLS; EOSINOPHILS; and BASOPHILS. Interleukin-3 receptors are formed by the dimerization of the INTERLEUKIN-3 RECEPTOR ALPHA SUBUNIT and the CYTOKINE RECEPTOR COMMON BETA SUBUNIT.
Interleukin-12 Subunit p40
Receptors, Antigen, T-Cell
Molecules on the surface of T-lymphocytes that recognize and combine with antigens. The receptors are non-covalently associated with a complex of several polypeptides collectively called CD3 antigens (ANTIGENS, CD3). Recognition of foreign antigen and the major histocompatibility complex is accomplished by a single heterodimeric antigen-receptor structure, composed of either alpha-beta (RECEPTORS, ANTIGEN, T-CELL, ALPHA-BETA) or gamma-delta (RECEPTORS, ANTIGEN, T-CELL, GAMMA-DELTA) chains.
Bone Marrow Cells
Interleukin-18 Receptor alpha Subunit
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Promoter Regions, Genetic
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.
Amino Acid Sequence
Bronchoalveolar Lavage Fluid
Glycoproteins found in a subfraction of normal mammalian plasma and urine. They stimulate the proliferation of bone marrow cells in agar cultures and the formation of colonies of granulocytes and/or macrophages. The factors include INTERLEUKIN-3; (IL-3); GRANULOCYTE COLONY-STIMULATING FACTOR; (G-CSF); MACROPHAGE COLONY-STIMULATING FACTOR; (M-CSF); and GRANULOCYTE-MACROPHAGE COLONY-STIMULATING FACTOR; (GM-CSF).
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.
A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445)

Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
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.
A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
Interleukin-11 Receptor alpha Subunit
Transforming Growth Factor beta
A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.
The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.
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.
Leukemia Inhibitory Factor
Intercellular Adhesion Molecule-1
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.
Recombinant Fusion Proteins
Interleukin Receptor Common gamma Subunit
An interleukin receptor subunit that was originally discovered as a component of the INTERLEUKIN 2 RECEPTOR. It was subsequently found to be a component of several other receptors including the INTERLEUKIN 4 RECEPTOR, the INTERLEUKIN 7 RECEPTOR, the INTERLEUKIN-9 RECEPTOR, the INTERLEUKIN-15 RECEPTOR, and the INTERLEUKIN-21 RECEPTOR. Mutations in the gene for the interleukin receptor common gamma chain have been associated with X-LINKED COMBINED IMMUNODEFICIENCY DISEASES.
Toll-Like Receptor 4
Granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. Like the BASOPHILS, mast cells contain large amounts of HISTAMINE and HEPARIN. Unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. Mast cells, derived from the bone marrow stem cells, are regulated by the STEM CELL FACTOR.
Janus Kinase 3
Proteins that are secreted into the blood in increased or decreased quantities by hepatocytes in response to trauma, inflammation, or disease. These proteins can serve as inhibitors or mediators of the inflammatory processes. Certain acute-phase proteins have been used to diagnose and follow the course of diseases or as tumor markers.
Receptors, Interleukin-1 Type II
An interleukin-1 receptor subtype that competes with the INTERLEUKIN-1 RECEPTOR TYPE I for binding to INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The interleukin-1 type II receptor appears to lack signal transduction capability. Therefore it may act as a "decoy" receptor that modulates the activity of its ligands. Both membrane-bound and soluble forms of the receptor have been identified.
A cytokine with both pro- and anti-inflammatory actions that depend upon the cellular microenvironment. Oncostatin M is a 28 kDa monomeric glycoprotein that is similar in structure to LEUKEMIA INHIBITORY FACTOR. Its name derives from the the observation that it inhibited the growth of tumor cells and augmented the growth of normal fibroblasts.
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.
Culture Media, Conditioned
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.
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
Receptors, Tumor Necrosis Factor
A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage. It is necessary for normal development of immunologic function early in life. By puberty, it begins to involute and much of the tissue is replaced by fat.
Dose-Response Relationship, Immunologic
Characterization of CD4+ CD8alphaalpha+ and CD4-CD8alphaalpha+ intestinal intraepithelial lymphocytes in rats. (1/1614)Intestinal intraepithelial lymphocytes (i-IEL) of aged rats comprise CD4+CD8alphaalpha+ and CD4-CD8alphaalpha+ T cells expressing TCR alphabeta. In the present study, we compared characteristics between CD4+CD8alphaalpha+ and CD4-CD8alphaalpha+ i-IEL, which were purified by a cell sorter from the i-IEL of 6-month-old Lewis rats. Most of the CD4+CD8alphaalpha+ i-IEL were of the CD44(hlgh) phenotype, while CD4-CD8alphabeta+ i-IEL were CD44(low). Vbeta usage in the CD4-CD8alphaalpha+ i-IEL was much diversified, while CD4+CD8alphaalpha+ i-IEL showed a skewed Vbeta repertoire. The CD4+CD8alphaalpha+ i-IEL but not the CD4-CD8alphaalpha+ i-IEL proliferated in response to syngeneic spleen cells, which was partially inhibited by addition of anti-MHC class I mAb. The CD4+CD8alphaalpha+ i-IEL produced IFN-gamma and IL-2 but no IL-4 or transforming growth factor (TGF)-beta in response to syngeneic spleen cells, while CD4-CD8alphaalpha+ i-IEL produced abundant levels of TGF-beta but no IL-2, IFN-gamma or IL-4. CD4+CD8alphaalpha+ i-IEL proliferated in response to exogenous IL-2 but not to IL-15, while CD4-CD8alphaalpha+ i-IEL could respond to IL-15 as well as IL-2. These results suggest that a significant fraction of CD4+CD8alphaalpha+ i-IEL belongs to Th1-type T cells capable of responding to self-MHC class I, while CD4-CD8alphaalpha+ i-IEL are a unique population with a diversified Vbeta repertoire that respond to IL-15 in rats.

IL-5 induces IgG1 isotype switch recombination in mouse CD38-activated sIgD-positive B lymphocytes. (2/1614)Mouse B cells express CD38, whose ligation by anti-CD38 Ab induces their proliferation and protection from apoptosis. We previously showed that stimulation of mouse splenic B cells with IL-5 together with CS/2, an anti-mouse CD38 mAb, induces production of IgG1 and IgM. Here we examined the role of IL-5 and CS/2 in the expression of germline gamma1 transcripts and the generation of reciprocal products forming DNA circles as byproducts of mu-gamma1 switch recombination. By itself, CS/2 induced significant expression of germline gamma1 transcripts in splenic naive B cells, whereas IL-5 neither induced nor enhanced germline gamma1 expression. Increased cellular content of reciprocal product, which is characteristic of mu-gamma1 recombination, was not observed after culturing B cells with CS/2, but increased reciprocal product, along with high levels of lgG1 secretion, was found when B cells were cultured with CS/2 plus IL-5. Although IL-4 did not, by itself, induce mu-gamma1 recombination in B cells stimulated with CS/2, in conjunction with CS/2 plus IL-5, IL-4 dramatically enhanced sterile gamma1 transcription and IgG1 production. These results demonstrate that CD38 ligation induces only germline gamma1 transcription and that IL-5 promotes both mu-gamma1 switch recombination and lgG1 secretion in an IL-4-independent manner.

Endogenous platelet-activating factor is critically involved in effector functions of eosinophils stimulated with IL-5 or IgG. (3/1614)Eosinophil activation and subsequent release of inflammatory mediators are implicated in the pathophysiology of allergic diseases. Eosinophils are activated by various classes of secretagogues, such as cytokines (e.g., IL-5), lipid mediators (e.g., platelet-activating factor (PAF)), and Ig (e.g., immobilized IgG). However, do these agonists act directly on eosinophils or indirectly through the generation of intermediate active metabolites? We now report that endogenous PAF produced by activated eosinophils plays a critical role in eosinophil functions. Human eosinophils produced superoxide when stimulated with immobilized IgG, soluble IL-5, or PAF. Pretreating eosinophils with pertussis toxin abolished their responses to these stimuli, suggesting involvement of a metabolite(s) that acts on G proteins. Indeed, PAF was detected in supernatants from eosinophils stimulated with IgG or IL-5. Furthermore, structurally distinct PAF antagonists, including CV6209, hexanolamine PAF, and Y-24180 (israpafant), inhibited IgG- or IL-5-induced superoxide production and degranulation. Previous reports indicated that exogenous PAF stimulates eosinophil eicosanoid production through formation of lipid bodies. We found in this study that IgG or IL-5 also induces lipid body formation and subsequent leukotriene C4 production mediated by endogenous PAF. Finally, inhibition of cytosolic phospholipase A2, one of the key enzymes involved in PAF synthesis, attenuated both PAF production and effector functions of eosinophils. These findings suggest that endogenous PAF plays important roles in eosinophil functional responses to various exogenous stimuli, such as cytokines and Igs. Therefore, inhibition of PAF synthesis or action may be beneficial for the treatment of eosinophilic inflammation. (+info)
IL-5 and eosinophils are essential for the development of airway hyperresponsiveness following acute respiratory syncytial virus infection. (4/1614)Viral respiratory infections can cause bronchial hyperresponsiveness and exacerbate asthma. In mice, respiratory syncytial virus (RSV) infection, which induces an immune response dominated by IFN-gamma, results in airway hyperresponsiveness (AHR) and eosinophil influx into the airways, both of which are prevented by pretreatment with anti-IL-5 Ab. To delineate the role of IL-5, IL-4, and IFN-gamma in the development of RSV-induced AHR and lung eosinophilia, we tested the ability of mice deficient in each of these cytokines to develop these symptoms of RSV infection. Mice deficient in either IL-5, IL-4, or IFN-gamma were administered infectious RSV intranasally, and 6 days later, airway responsiveness to inhaled methacholine was assessed by barometric body plethysmography, and numbers of lung eosinophils and production of IFN-gamma, IL-4, and IL-5 by mononuclear cells from peribronchial lymph nodes were monitored. RSV infection resulted in airway eosinophilia and AHR in both IL-4- and IFN-gamma-deficient mice, but not in IL-5-deficient mice. Reconstitution of IL-5-deficient mice with IL-5 restored these responses and enhanced the responses in IL-4-deficient mice. Anti-VLA-4 (very late Ag-4) treatment prevented lung eosinophilia and AHR following RSV infection and IL-5 reconstitution. We conclude that in response to RSV, IL-5 is essential for the influx of eosinophils into the lung and that eosinophils in turn are critical for the development of AHR. IFN-gamma and IL-4 are not essential for these responses to RSV infection. (+info)
Optimal proliferation of a hematopoietic progenitor cell line requires either costimulation with stem cell factor or increase of receptor expression that can be replaced by overexpression of Bcl-2. (5/1614)In vitro proliferation of hematopoietic stem cells requires costimulation by multiple regulatory factors whereas expansion of lineage-committed progenitor cells generated by stem cells usually requires only a single factor. The distinct requirement of factors for proliferation coincides with the differential temporal expression of the subunits of cytokine receptors during early stem cell differentiation. In this study, we explored the underlying mechanism of the requirement of costimulation in a hematopoietic progenitor cell line TF-1. We found that granulocyte-macrophage colony-stimulating factor (GM-CSF) optimally activated proliferation of TF-1 cells regardless of the presence or absence of stem cell factor (SCF). However, interleukin-5 (IL-5) alone sustained survival of TF-1 cells and required costimulation of SCF for optimal proliferation. The synergistic effect of SCF was partly due to its anti-apoptosis activity. Overexpression of the IL-5 receptor alpha subunit (IL5Ralpha) in TF-1 cells by genetic selection or retroviral infection also resumed optimal proliferation due to correction of the defect in apoptosis suppression. Exogenous expression of an oncogenic anti-apoptosis protein, Bcl-2, conferred on TF-1 cells an IL-5-dependent phenotype. In summary, our data suggested SCF costimulation is only necessary when the expression level of IL5Ralpha is low and apoptosis suppression is defective in the signal transduction of IL-5.

CD8 T cells are essential in the development of respiratory syncytial virus-induced lung eosinophilia and airway hyperresponsiveness. (6/1614)Viral respiratory infections can cause bronchial hyperresponsiveness and exacerbate asthma. In mice, respiratory syncytial virus (RSV) infection results in airway hyperresponsiveness (AHR) and eosinophil influx into the airways. The immune cell requirements for these responses to RSV infection are not well defined. To delineate the role of CD8 T cells in the development of RSV-induced AHR and lung eosinophilia, we tested the ability of mice depleted of CD8 T cells to develop these symptoms of RSV infection. BALB/c mice were depleted of CD8 T cells using anti-CD8 Ab treatment before intranasal administration of infectious RSV. Six days postinfection, airway responsiveness to inhaled methacholine was assessed by barometric body plethysmography, and numbers of lung eosinophils and levels of IFN-gamma, IL-4, and IL-5 in bronchoalveolar lavage fluid were monitored. RSV infection resulted in airway eosinophilia and AHR in control mice, but not in CD8-depleted animals. Further, whereas RSV-infected mice secreted increased amounts of IL-5 into the airways as compared with noninfected controls, no IL-5 was detectable in both bronchoalveolar lavage fluid and culture supernatants from CD8-depleted animals. Treatment of CD8-depleted mice with IL-5 fully restored both lung eosinophilia and AHR. We conclude that CD8 T cells are essential for the influx of eosinophils into the lung and the development of AHR in response to RSV infection. (+info)
Inhibition of matrix metalloproteinases prevents allergen-induced airway inflammation in a murine model of asthma. (7/1614)Although matrix metalloproteinases (MMPs) have been reported to play crucial roles in the migration of inflammatory cells through basement membrane components in vitro, the role of MMPs in the in vivo accumulation of the cells to the site of inflammation in bronchial asthma is still obscure. In this study, we investigated the role of MMPs in the pathogenesis of bronchial asthma, using a murine model of allergic asthma. In this model, we observed the increase of the release of MMP-2 and MMP-9 in bronchoalveolar lavage fluids after Ag inhalation in the mice sensitized with OVA, which was accompanied by the infiltration of lymphocytes and eosinophils. Administration of tissue inhibitor of metalloproteinase-2 to airways inhibited the Ag-induced infiltration of lymphocytes and eosinophils to airway wall and lumen, reduced Ag-induced airway hyperresponsiveness, and increased the numbers of eosinophils and lymphocytes in peripheral blood. The inhibition of cellular infiltration to airway lumen was observed also with tissue inhibitor of metalloproteinase-1 and a synthetic matrix metalloproteinase inhibitor. These data suggest that MMPs, especially MMP-2 and MMP-9, are crucial for the infiltration of inflammatory cells and the induction of airway hyperresponsiveness, which are pathophysiologic features of bronchial asthma, and further raise the possibility of the inhibition of MMPs as a therapeutic strategy of bronchial asthma.

Roles of TH1 and TH2 cytokines in a murine model of allergic dermatitis. (8/1614)Skin lesions in atopic dermatitis (AD) are characterized by hypertrophy of the dermis and epidermis, infiltration by T cells and eosinophils, and expression of the cytokines IL-4, IL-5, and IFN-gamma. The role of these cytokines in the pathogenesis of AD is not known. We took advantage of a recently described murine model of AD elicited by epicutaneous sensitization with ovalbumin (OVA) (1) and of the availability of mice with targeted deletions of the IL-4, IL-5, and IFN-gamma cytokine genes to assess the role of these cytokines in this model.OVA-sensitized skin from IL-5(-/-) mice had no detectable eosinophils and exhibited decreased epidermal and dermal thickening. Sensitized skin from IL-4(-/-) mice displayed normal thickening of the skin layers but had a drastic reduction in eosinophils and a significant increase in infiltrating T cells. These findings were associated with a reduction in eotaxin mRNA and an increase in mRNA for the T-cell chemokines macrophage inflammatory protein-2 (MIP-2), MIP-1beta, and RANTES. Sensitized skin from IFN-gamma-/- mice was characterized by reduced dermal thickening. These results suggest that both the TH2 cytokines IL-4 and IL-5 and the TH1 cytokine IFN-gamma play important roles in the inflammation and hypertrophy of the skin in AD. (+info)
Effect of interleukin-5 and granulocyte-macrophage colony stimulating factor on in vitro eosinophil function: comparison with...
Eosinophils are hypothesized to be crucial in the development of allergic airway inflammation; however, the actual mechanisms that determine their inflammatory activity are still largely undefined. To investigate the factors that regulate eosinophil function in allergic airway disease, we have previously used segmental bronchoprovocation with allergen to study ex vivo eosinophil function. To determine whether the functional changes associated with airway eosinophils obtained by bronchoalveolar lavage 48 hours after antigen challenge are caused by exposure to airway-generated cytokines, normodense blood eosinophils were cultured in vitro with recombinant human interleukin-5 (IL-5) or granulocyte-macrophage colony stimulating factor (GM-CSF). The effect of cytokine exposure was then evaluated on selected cell functions. In vitro incubation with these cytokines for 24 hours significantly increased eosinophil membrane expression of CD18 and CD11b compared with culture in medium alone or eosinophils obtained

GM-CSF), and IL-5. Activated T cells likely are the principal sources of IL-3, GM-CSF, and IL-5 that induce eosinophil differentiation in bone marrow. However, depending on pathogenic stimuli, eosinophilopoietic cytokines may be released by other cell types, including mast cells, macrophages, natural killer cells, endothelial cells, epithelial cells, fibroblasts, and even eosinophils, themselves.4 IL-3 and GM-CSF are pluripotent cytokines that have effects on other hematopoietic lineages. IL-5 is the most selective eosinophil-active cytokine, but it is relatively late acting. Although it is both necessary and sufficient for eosinophil differentiation, IL-5 demonstrates maximum activity on the IL-5 receptor (IL-5R)-positive eosinophil progenitor pool that first is expanded by earlier acting pluripotent cytokines such as IL-3 and GM-CSF4; expression of the high affinity IL-5R is a prerequisite for eosinophil development. Exodus from the bone marrow also is regulated by IL-5. IL-3, GM-CSF, along ...
The current presence of eosinophils in the lung is often seen | Selective Sirt2 inhibition by ligand-induced rearrangement
The current presence of eosinophils in the lung is often seen as a defining feature of asthma. through rules of eosinophil progenitor creation.

2016 Group 7 Project - CellBiology
Following maturation and/or activation, eosinophils (as well as their progenitors) are mobilised, released from bone marrow into circulation and trafficked to tissue sites. A large proportion of these mature eosinophils will remain in bone marrow. Once eosinophils enter circulation, they have a half-life of approximately 8-18 hours. Under normal conditions, the vast majority of eosinophils are located in tissues (the tissue/blood eosinophil ratio is about 100:1) and upon gaining entrance to a tissue, most do not recirculate. They have a life span ranging from 2 to 5 days, however locally produced cytokines such as IL-5, IL-3, GM-CSF, IL-33, and interferon-γ may increase this survival time (up to 12 days). Eosinophils are predominantly trafficked to mucosal surfaces of the respiratory, lower genitourinary and gastrointestinal tracts where they reside within the lamina propria (excluding the oesophagus). They are also localised within the thymus (medulla and junction ...

YM-90709 | CAS#163769-88-8 | interleukin-5 receptor antagonist | MedKoo
YM-90709 is an interleukin-5 receptor antagonist. YM-90709 inhibits the binding of IL-5 to its receptor on peripheral human eosinophils and butyric acid-treated eosinophilic HL-60 clone 15 cells, with IC50 values of 1.0 and 0.57 microM, respectively. In functional assays, YM-90709 inhibited IL-5-prolonged eosinophil survival with an IC50 value of 0.45 microM and did not affect the GM-CSF-prolonged eosinophil survival. Furthermore, YM-90709 inhibited the IL-5-induced but not GM-CSF-induced tyrosine phosphorylation of Janus kinase 2 (JAK2) in eosinophilic HL-60 clone 15 cells.
Tumour necrosis factor-α regulates human eosinophil apoptosis via ligation of TNF-receptor 1 and balance between NF-κB and AP-1
Eosinophils play a central role in asthma. The present study was performed to investigate the effect of tumour necrosis factor-α (TNF-α) on longevity of isolated human eosinophils. In contrast to Fas, TNF-α inhibited eosinophil apoptosis as evidenced by a combination of flow cytometry, DNA fragmentation assay and morphological analyses. The effect of TNF-α on eosinophil apoptosis was reversed by a TNF-α neutralising antibody. The anti-apoptotic effect of TNF-α was not due to autocrine release of known survival-prolonging cytokines interleukins 3 and 5 or granulocyte-macrophage-colony-stimulatingfactor as their neutralisation did not affect the effect of TNF-α. The anti-apoptotic signal was mediated mainly by the TNF-receptor 1. TNF-α induced phosphorylation and degradation of IκB and an increase in NF-κB DNA-binding activity. The survival-prolonging effect of TNF-α was reversed by inhibitors of NF-κB pyrrolidinedithiocarbamate and gliotoxin and by an inhibitor of IκB kinase, ...

TY - JOUR. T1 - Role of IL-10 in the resolution of airway inflammation. AU - Ogawa, Yoshiko. AU - Duru, Enrico A.. AU - Ameredes, Bill. PY - 2008/8. Y1 - 2008/8. N2 - IL-10 can be considered an important agent in the resolution of inflammation. Originally named cytokine synthesis inhibitory factor for its ability to inhibit IFN-y and IL-2 production in Th2 cells, it is secreted by monocytes, macrophages, mast cells, T and B lymphocytes, and dendritic cells (DCs). IL-10 production and release by monocytic cells in response to allergic challenge is upregulated by TNF-α, and by negative feedback regulation of itself. However, it is also secreted by T regulatory cells (Tregs), under the control of IL-2. Importantly in the context of asthma, IL-10 inhibits eosinophilia, by suppression of IL-5 and GM-CSF, by direct effects on eosinophil apoptosis, and effects on cell proliferation through down-regulation of IL-1. A number of its cytokine suppressive characteristics are now thought to occur through ...
Purified interleukin 5 supports the terminal differentiation and proliferation of murine eosinophilic precursors. | Journal of...
Using a clonal culture system, we investigated the hemopoietic effects of purified recombinant IL-5 obtained from conditioned media of transfected Xenopus oocytes. IL-5 alone acted on untreated bone marrow cells and supported the formation of a small number of colonies, all of which were predominantly eosinophilic. However, it did not support colony formation by spleen cells from 5-FU-treated mice, in which only primitive stem cells had survived, while IL-3 and G-CSF did. Eosinophil-containing colonies were formed from these cells in the presence of IL-5 and G-CSF together. In contrast, G-CSF alone did not support any eosinophil colonies. The eosinophilopoietic effect of IL-5 was dose-dependent, and was neutralized specifically by anti-IL-5 antibody. To exclude the possibility of interactions with accessory cells in the same culture dish, we replated a small number (200 cells/dish) of enriched hemopoietic progenitors, obtained from blast cell colonies, which were formed by cultivation of spleen ...

Real-world mepolizumab in the prospective severe asthma REALITI-A study: initial analysis | European Respiratory Society
The REALITI-A study is a prospective, global, observational, self-controlled cohort study being conducted to collect real-world data from patients with asthma who were newly prescribed mepolizumab treatment. These initial results showed real-world mepolizumab initiation led to significant reductions in the annual asthma exacerbation rate and clinically meaningful reductions in daily maintenance OCS dose versus pre-mepolizumab treatment. Furthermore, there were no new safety concerns with mepolizumab when compared with results from previous randomised controlled trials (RCTs). These initial data confirm mepolizumab effectiveness in a real-world setting.. We found the rates of clinically significant exacerbations and exacerbations requiring hospitalisation and/or emergency department visit were significantly reduced with mepolizumab treatment initiation versus before initiation. Reductions in clinically significant exacerbations were observed regardless of older age, maintenance OCS at enrolment ...

Eosinophilia Associated With CD3 − CD4 + T Cells: Characterization and Outcome of a Single-Center Cohort of 26 Patients -...
Background: Lymphocytic variant hypereosinophilic syndrome is characterized by marked over-production of eosinophilopoietic factor(s) by dysregulated T cells leading to eosinophil expansion. In most cases, these T cells are clonal and express a CD3−CD4+ phenotype. As this is a rare disorder, presenting manifestations, disease course, treatment responses, and outcome are not well-characterized. Materials and Methods: In this retrospective single-center observational study, we reviewed medical files of all patients with persistent hypereosinophilia seen between 1994 and 2019 in whom CD3−CD4+ T cells were detected. Data collection included clinical and biological findings at presentation, treatment responses, disease course, and serial CD3−CD4+ T cell counts. Results: Our cohort comprises 26 patients, including 2 with hypereosinophilia of undetermined significance. All 24 symptomatic patients had cutaneous lesions and/or angioedema, and fasciitis was present in several
Eosinophilia - Mayo Clinic
Eosinophilia (e-o-sin-o-FILL-e-uh) is a higher than normal level of eosinophils. Eosinophils are a type of disease-fighting white blood cell. This condition most often indicates a parasitic infection, an allergic reaction or cancer.. You can have high levels of eosinophils in your blood (blood eosinophilia) or in tissues at the site of an infection or inflammation (tissue eosinophilia).. Tissue eosinophilia may be found in samples taken during an exploratory procedure or in samples of certain fluids, such as mucus released from nasal tissues. If you have tissue eosinophilia, the level of eosinophils in your bloodstream is likely normal.. Blood eosinophilia may be detected with a blood test, usually as part of a complete blood count. A count of more than 500 eosinophils per microliter of blood is generally considered eosinophilia in adults. A count of more than 1,500 eosinophils per microliter of blood that lasts for several months is called hypereosinophilia.. Eosinophils play two roles in your ...

This study is the first to provide clinical insights into the role of peripheral blood eosinophil level in patients with COPD complicated with CAP requiring IMV and admission to an ICU. The important findings are the associations between peripheral blood eosinophil level and severity of lung function, leucocyte count and in-ICU treatment outcomes in terms of prolonged RICU admission (RICU length of stay ,14 days) and a distinct bacterial profile for the cause of CAP in this population.. The strengths of this study include that all participants had spirometric data to confirm the diagnosis of COPD, and that the bacteriology was profiled using samples collected via transbronchial aspirates on insertion of an endotracheal tube. In addition, this study population has never previously been studied with regard to the relationship between peripheral blood eosinophil level and clinical characteristics, bacteriology of EAs and clinical outcomes. This ensures a valid study population of patients with COPD ...
IL-33 markedly induces murine eosinophil gene transcription via autocrine IL-4-dependent and -independent mechanisms - omicX
Eosinophils are major effector cells in type 2 inflammatory responses and become activated in response to IL-4 and IL-33, yet the molecular mechanism remains unclear. We examined the direct effect of these cytokines on eosinophils and demonstrated that murine eosinophils respond to IL-4 and IL-33 by phosphorylation of STAT-6 and NFkB, respectively. RNA sequencing analysis of murine eosinophils indicated that IL-33 regulates 519 genes, whereas IL-4 regulates only 28 genes, including 19 IL-33-regulated genes. Interestingly, IL-33 induced eosinophil activation via two distinct mechanisms, IL-4 independent and IL-4 secretion/auto-stimulation dependent. Anti-IL-4 or anti-IL-4Ra antibody-treated eosinophils, as well as Il4- or Stat6-deficient eosinophils, had attenuated protein secretion of a subset of IL-33-induced genes, including Retnla and Ccl17. However, the induction of most IL-33-regulated transcripts (e.g. Il6 and Il13) was IL-4 independent and blocked by NFkB inhibition. Indeed, IL-33 induced the

Effects of the cyclin-dependent kinase inhibitor R-roscovitine on eosinophil survival and clearance - UEA Digital Repository
Background: Eosinophils are pro-inflammatory cells implicated in the pathogenesis of asthma and atopy. Apoptosis has been proposed as a potential mechanism underlying the resolution of eosinophilic inflammation and studies have indicated the ability of interventions that induce human eosinophil apoptosis to promote the resolution of eosinophilic inflammation. Recently, the cyclin-dependent kinase (CDK) inhibitor R-roscovitine was shown to enhance neutrophil apoptosis and promote the resolution of neutrophilic inflammation. Objective: The purpose of this study was to examine the expression of CDKs in human blood eosinophils, the effects of R-roscovitine on eosinophil survival in vitro and whether R-roscovitine could influence eosinophilic lung inflammation in vivo. Methods: Eosinophils were isolated from human peripheral blood and the effects of R-roscovitine on apoptosis, degranulation and phagocytic uptake examined in vitro. The effects of R-roscovitine on eosinophilic lung inflammation in vivo ...

Characterisation of an OCS-dependent severe asthma population treated with mepolizumab | Thorax
Mepolizumab, an anti-interleukin 5 monoclonal antibody under development for severe asthma, has been shown to reduce peripheral and sputum eosinophils.1 ,2 Mepolizumab is hypothesised to work by reducing eosinophilic driven airway inflammation. Mepolizumab has previously been shown to be steroid sparing in a small study.1 The DREAM study (NCT01000506) reported that mepolizumab can reduce the exacerbation rate by 39-52% in a severe asthma population.2 Approximately a third of the subjects (n=188) who participated in the DREAM study were using daily oral corticosteroids (OCS) at baseline in addition to using high dose inhaled corticosteroid and an additional controller to treat their asthma. This group reported an average duration of OCS use of 4.1 years, a mean OCS dose of 17 mg/day and a median peripheral blood baseline eosinophil level of 280 cells/µL, which was similar to that for the non-OCS dependent subgroup (290 cells/µL) (table 1). Sputum eosinophils levels were also similar between the ...
Airway Eosinophils: Allergic Inflammation Recruited Professional Antigen-Presenting Cells | The Journal of Immunology
In allergic diseases of the upper and lower airways, eosinophils are characteristically recruited from the bloodstream into the tissues and lumina of the airways and are present in respiratory secretions from the nose and lungs. As such, intraluminal and tissue eosinophils are exposed to inhaled allergens. In the present study, we assessed whether recruited airway eosinophils might serve as distinct inflammatory APCs for airway Ags in mediating T cell responses. Normal lungs contain several cell types, DCs, B cells, and macrophages, in their airways and parenchyma capable of acting as professional APCs (28, 29, 30). Native lung myeloid DCs, likely indicative of regulatory mechanisms that restrain local lung T cell activation, lack the full functional capabilities of Ag-processing APCs in that they can present antigenic peptides but not whole proteins to naive CD4+ T cells (28). Lung myeloid DCs, however, acquire the full capabilities of professional APCs following in vitro exposures to ...

Background: Tumor associated tissue eosinophilia (TATE) is believed to play a significant role in biological behavior of the carcinoma. Eosinophils are involved in immune reaction. Various studies have been carried out regarding their role in tumor progression or regulation. In oral squamous cell carcinoma (OSCC), eosinophils are associated with favourable or unfavourable prognosis and hence their role is yet unclear. To compare the tissue eosinophils in OSCC and normal tissue and to correlate the expression of TATE in different grades of OSCC. Method: Study comprised 30 cases, 6 normal and 24 histopathologically diagnosed with OSCC. 4 micron thick sections were stained using 1% congo red solution. The sections were examined under high power (×40) and 10 consecutive microscopic fields were studied. The average number of eosinophils were statistically analysed. Results: The tabulated results showed that the median value of tissue eosinophils, increased in OSCC compared to normal mucosa. Analysis ...
An abnormally high number of eosinophils in the blood. Normally, eosinophils constitute 1 to 3% of the peripheral blood leukocytes, at a count of 350 to 650 per cubic millimeter. Eosinophilia can be categorized as mild (less than 1500 eosinophils per cubic millimeter), moderate (1500 to 5000 per cubic millimeter), or severe (more than 5000 per cubic millimeter). In areas of the world where parasitic diseases are common, they are the usual cause of eosinophilia. In developed nations, eosinophilia is most often due to allergy or, less often, a drug reaction. There are numerous other causes of eosinophilia, but individually they are quite uncommon. Eosinophilia may be primary or secondary. In primary eosinophilia, the increased production of eosinophils is due to an abnormality in a hematopoietic stem cell as, for example, in eosinophilic leukemia. In secondary eosinophilia, the increased production of eosinophils is a reactive process driven by cytokines, as is the case in allergy. ...
Enhanced Interleukin (IL)-13 Responses in Mice Lacking IL-13 Receptor α 2 | JEM
In this report we describe the generation of mice deficient in IL-13Rα2 to define the role of this receptor chain in IL-13 responses. IL-13Rα2 may act to modulate the effects of IL-13 in vivo in various ways. IL-13Rα2 could enhance IL-13 activities by increasing the strength of IL-13 signaling or attenuate IL-13 effects by negative signaling or simply as a molecular decoy. Attenuating roles of IL-13Rα2 could explain the lack of evidence for IL-13 effects on T cells or an enhancing role could explain the effect of IL-13 effect on airways hyperreactivity and eosinophil survival distinct from IL-4.. Interestingly, we find that the absence of IL-13Rα2 correlates with nearly complete loss of serum IL-13 and an increase in tissue IL-13 in IL-13Rα2−/− mice. The lack of serum IL-13 cannot be explained by a lack of IL-13 production in IL-13Rα2−/− mice as IL-13 is present in tissues of IL-13Rα2−/− and is produced by activated IL-13Rα2−/− immune cells. Serum IL-13Rα2 may act as a ...

Notes from Dr. RW: The asthma-COPD overlap syndrome (ACOS)
Summary: The relevance of the ACOS is to identify patients with COPD who may have underlying eosinophilic inflammation that responds to inhaled corticosteroids. So far, the previous diagnosis of asthma in a patient with COPD is the more reliable criterion for ACOS. Ongoing studies will clarify if concentrations of blood eosinophils may be useful to identify this subgroup of patients with COPD. If this is the case, the interest of ACOS may shift to that of eosinophilic COPD, which is easier to diagnose and has clear therapeutic implications. ...

- Our data do not support a role for IL-5 levels and eosinophil count in intima-media thickness, however SNPs associated with IL-5 and eosinophils might influence stability of the atherosclerotic plaque via modulation of RAD50 levels. (ox.ac.uk)
- Data on the comparative efficacy of treatments would be valuable for clinicians making decisions about patients who are potential candidates for IL-5Rα or anti-IL-5 treatments. (ersjournals.com)
