Chemokines belong to a class of pro-inflammatory cytokines that have the ability to attract and activate leukocytes. Their name is derived from chemotactic cytokines based on their ability to induce and mediate chemotaxis in nearby responsive cells. Formerly, they were called SIS family of cytokines, SIG family of cytokines, SCY family of cytokines, Platelet factor-4 superfamily or intercrines. Chemokines can be divided into at least four structural branches: c (chemokines, c), cc (chemokines, cc), cx3c (chemokines, cx3c), and cxc (chemokines, cxc). The classification is according to the variations in a shared cysteine motif. Chemokines may also be classified based on their functions. Homeostatic chemokines are chemokines that are responsible for basal leukocyte migration. Examples of homeostatic chemokines are CCL14, CCL19, CCL20, CCL21, CXCL12 and CXCL13. Nevertheless, some of them are not exclusive to this function. For instance, CCL20 is also associated with inflammation since it can act as ...

Migration of T-lymphocytes on a surface coated with extracellular matrix (ECM) components (two-dimensional (2-D) migration) and migration (infiltration) into a matrix (Three-dimesional (3-D) migration) are complex events and the underlying mechanisms are not yet fully understood. Here 2-D and 3-D migration were studied by use of seven leukemic T-cell lines representing discrete differentiation stages, a non-leukemic T-cell clone, and normal peripheral blood T cells. peripheral blood lymphocytes and the T-cell clone produced nanogram quantities of various chemokines, as compared to a production of ≤ 0.05 ng/ml by the T leukemia cell lines. In a Boyden chamber system, the leukemic T-cell lines showed haptotactic migration on fibronectin. The migration was augmented bu exposure to chemokines, including RANTES, MIP-1α, MIP-1β, and IL-8. The T-cell lines showed a peak response at a chemokine concentration of 10-50 ng/ml, whereas the T-cell clone responded optimally at 100 ng/ml. In contrast to a ...

This study focuses upon three chemokines, namely CCL5, CXCL10 and CCL3, which are potential novel therapeutic targets in arthritis. The aim of the study was to analyse the expression and production of these three chemokines within the joints of children with juvenile idiopathic arthritis (JIA) of the oligoarticular and polyarticular subtypes. All three of these chemokines are highly expressed at the level of mRNA, with the most significant increase in mRNA levels being demonstrated for CCL5 when compared with matched peripheral blood samples and controls. We show that high levels of all three chemokines are present in synovial fluid of children with JIA. We investigate the major source of CCL5 from inflammatory synovial cells, which we show to be CD8+ T cells. This CD8+ synovial T cell population has an unexpected phenotype that has not been described previously, being CCR7- yet predominantly CD28+ and CD45RA-. These cells contain high levels of stored intracellular CCL5, and rapid release of CCL5 takes

Cells were first stained with anti- CD16/32 (2.4G2) for 10 minutes at 4C, then with ETP-46321 specifically conjugated antibodies for 30 minutes at 4C in the dark. to anti-PD-1, and their induction in non- responsive murine tumors promoted responsiveness to anti-PD-1. Our data suggest that the CXCR3 chemokine system is usually a biomarker for sensitivity to PD-1 blockade and that augmenting the intratumoral function of EMR2 this chemokine system could improve clinical outcomes. eTOC Blurb Chow et al. find the CXCR3 chemokine system is not required for CD8+ T cell migration into the tumor, but rather for the enhancement of the intratumoral CD8+ T cell response in the context of PD-1 blockade. The CXCR3 chemokine system may serve as a biomarker for sensitivity to PD- 1 blockade and a target for improving clinical outcomes. Introduction CD8+ T cells play a vital role in tumor eradication through the production of cytotoxic molecules, such as perforin and granzyme, and cytokines, such as interferon ...

We have characterized previously the expression of the chemokines eotaxin, MCP-5, RANTES, and MCP-1 (mRNA and/or protein), and correlated this with the leukocytes migrating to the lung during a murine model of lung inflammation ((5), (16)). From these experiments, we concluded that MCP-1 mRNA expression paralleled the accumulation of monocytes/macrophages in this organ, both events occurring predominantly at early stages of the response (day 15). Also, eotaxin mRNA expression paralleled lung eosinophilia predominantly at late stages (day 21). In contrast, other chemokines, such as RANTES or MCP-5, were expressed throughout the inflammatory reaction. This underlines the contribution of chemokines at different stages of the response.. From the work presented here, we first conclude that eosinophil recruitment and development of BHR in this model system involve the action of both eosinophilic (eotaxin, RANTES, MCP-5, and MIP-1α) and noneosinophilic chemokines (MCP-1). This indicates the absence of ...

The contribution of inflammation to the development of fibrosis varies in different conditions, and understanding the interaction between these processes is relevant to devise therapeutic strategies for chronic diseases such as pancreatitis. Identification of the chemokine system has elucidated the molecular mechanisms regulating leucocyte trafficking in a given tissue. Chemokines are a family of small cytokines that exert gradient dependent chemoattraction of cells bearing specific cognate receptors. The chemokine system is considerably complex, as indicated by the high number of ligands and receptors, and by the fact that the same chemokine may bind more than one receptor and the same receptor more than one chemokine.2 Additionally, the effects of chemokines are not limited to inflammation as the majority of cells express at least one chemokine receptor. A related aspect of chemokine biology is the distinction between homeostatic and inflammatory chemokines, where expression of the latter ...

Previous studies by our group and others have addressed the relationship between leukocyte infiltration into solid tumors and chemokine expression (14 , 16 , 23) . To our knowledge, this work is the first comprehensive study of CC chemokines and chemokine receptor expression in human ovarian cancer ascites.. We found that ascitic fluid is rich in CC chemokines and that the CD14-expressing cells and T cells present in ovarian cancer ascites express CC chemokine receptor mRNA and protein.. Is the extent and phenotype of the leukocyte infiltration in ovarian ascites related to chemokines and chemokine receptor expression? Gradients of chemokines usually cause tissue recruitment of leukocytes through effects on adhesion and endothelial transmigration (24) . Our data suggest that CC chemokine protein levels are significantly higher in ascitic fluid than in patient plasma samples. Therefore, chemokines present in ascites could form a gradient for leukocyte migration into the peritoneal cavity. ...

AU - Shames, Brian D.. AU - Pulido, Edward J.. AU - McIntyre, Robert C.. PY - 2001/3. Y1 - 2001/3. N2 - Chemokines stimulate the influx of leukocytes into tissues. Their production is regulated by nuclear factor-κB (NF-κB), an inducible transcription factor under the control of inhibitory factor κB-α (IκB-α). We have previously demonstrated that L-arginine (L-Arg) attenuates neutrophil accumulation and pulmonary vascular injury after administration of lipopolysaccharide (LPS). We hypothesized that L-Arg would attenuate the production of lung chemokines by stabilizing IκB-α and preventing NF-κB DNA binding. We examined the effect of L-Arg on chemokine production, IκB-α degradation, and NF-κB DNA binding in the lung after systemic LPS. To block nitric oxide (NO) production, a NO synthase inhibitor was ...

Atopic dermatitis is a chronic relapsing pruritic eczematous disease affecting between 15% and 20% of children, with a social, psychological and economical impact on the children and their families. After increasing during the 1970s and 1980s, the incidence of the disease seems to have levelled out in the 1990s. The cause of atopic dermatitis is still unknown, but detailed description of its pathogenesis has improved our understanding of the disorder and opened new possibilities for the development of more effective methods for its treatment. Histologically, the skin of atopic dermatitis patients is characterized by inflammation, with prevalent infiltration by lymphocytes but also mast cells, eosinophils, and macrophages, as well as dendritic cells. Attraction of these cells to the skin is in part mediated by chemokines. Small proteins belonging to four distinct families, chemokines mediate their effects by binding to chemokine receptors. Some chemokines can attract skin-specific lymphocytes and ...

Lung cancer cells express different chemokines and chemokine receptors that modulate leukocyte infiltration within tumor microenvironment. The released CXCL1 was functionally linked to recruiting monocytes into lung cancer cell microenvironment. and in Lewis lung carcinomas (LLC) [10]. In human airway epithelium and bronchoalveolar macrophages, monocyte chemoattractant protein-1 (MCP-1) and CXCL1 were buy BAM 7 constitutively expressed and upregulated buy BAM 7 by TNF- but not by lipopolysaccharide (LPS) [11]. In pathological conditions, various cancer and/or cancer cells express different chemokines and chemokine receptor that modulate leukocyte infiltration within tumor microenvironment, tumor growth and metastasis. For example, CXCL1 has been reported to be expressed in melanoma, breast, colon and ovarian cancer [3]. Non-small cell TSPAN11 lung cancer (NSCLC) biopsy specimens have high buy BAM 7 intratumoral concentrations of CXCR2 ligands (CXCL1, CXCL5, and CXCL8) and type 2 cytokines ...

Enhanced expression of chemotactic cytokines (aka chemokines) within pancreatic islets likely contributes to islet inflammation by regulating the recruitment and activation of various leukocyte populations, including macrophages, neutrophils, and T-lymphocytes. Because of the powerful actions of these chemokines, precise transcriptional control is required. In this review, we highlight what is known about the signals and mechanisms that govern the transcription of genes encoding specific chemokine proteins in pancreatic islet β-cells, which include contributions from the NF-κB and STAT1 pathways. We further discuss increased chemokine expression in pancreatic islets during autoimmune-mediated and obesity-related development of diabetes.

The prediction of aspirate type (NS, ACID, SNAP, and CASP) was performed using an approach recently defined by Hutson15 to extend standard ROC methodology.16 In brief, lung injury type was modeled as a 2 × 2 outcome with injury groups recoded as NS = (ACID = 0, particles = 0), ACID = (ACID = 1, particles = 0), SNAP = (ACID = 0, particles = 1), or CASP = (ACID = 1, particles = 1). In the foregoing, the two factors in injury type are ACID and particles, and the two levels for each factor are no = 0 and yes = 1. The basic algorithm used in predictive modeling considered the following population probability parameters given by Π00= Probability (NS) = Pr (ACID = no, particles = no); Π10= Pr (ACID) = Pr (ACID = yes, particles = no); Π01= Pr (SNAP) = Pr (ACID = no, particles = yes); and Π11= Pr (CASP) = Pr (ACID = yes, particles = yes). These population probability parameters were modeled as a function of a linear combination of cytokine levels under the constraint that they sum to 1, i.e. , ...

Immune abnormalities have been described in some individuals with autism spectrum disorders (ASDs) as well as their family members. However, few studies have directly investigated the role of prenatal cytokine and chemokine profiles on neurodevelopmental outcomes in humans. In the current study, we characterized mid-gestational serum profiles of 22 cytokines and chemokines in mothers of children with ASD (N=415), developmental delay (DD) without ASD (N=188), and general population (GP) controls (N=428) using a bead-based multiplex technology. The ASD group was further divided into those with intellectual disabilities (developmental/cognitive and adaptive composite score|70) (ASD+ID, N=184) and those without (composite score⩽70) (ASD-noID, N=201). Levels of cytokines and chemokines were compared between groups using multivariate logistic regression analyses, adjusting for maternal age, ethnicity, birth country and weight, as well as infant gender, birth year and birth month.

Statistical analyses of the data revealed that the ...

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 ...

The therapeutic goal in autoimmune diseases such as RA is to control disease, to establish remission, and eventually to cure. In theory, this goal can be achieved using either Ag-specific approaches, for example, elimination of self-reactive T cells (assuming that a finite number of key Ags can be identified as the target of the autoimmune process in RA), or the non-Ag-specific approaches, for example, blockade of cytokines as in the case of TNF-a neutralization. Currently, only the latter types of approaches have yielded clinical benefit, and it is in this category that approaches to block chemokines or receptors may be included. Despite their appeal in terms of effectiveness, non-Ag-specific approaches carry a higher risk of immunosuppression and opportunistic infections (48).. Although there is a myriad of ongoing clinical trials testing the effects of chemokine/receptor blockers in RA (Table 1), to date one cannot yet predict how many of the current targets will prove to be clinically ...

Researchers found that fibromyalgia patients have higher concentrations of inflammatory chemokines, a biomarker which could help diagnose FM.

Author Summary Although HIV, the causative agent of AIDS, establishes a lifelong infection that cannot be eradicated even with effective treatment, the host immune system has the ability to contain its replication for many years in which the disease remains asymptomatic. Key players in HIV control are CD8+ T cells, specialized immune cells that can not only destroy infected cells, but also secrete soluble factors that suppress the virus without killing infected cells. CD8+ T cells produce multiple HIV-suppressive factors, including certain chemokines (soluble proteins that attract immune cells), which block the virus even before it can gain access to its target cells. In the present study, we characterize a new anti-HIV chemokine, XCL1 or lymphotactin, which is primarily produced by CD8+ T cells. A unique feature of XCL1 is that, unlike other antiviral chemokines, it has a very broad spectrum of activity against different variants of HIV-1 and directly binds the virus outer coat, rather than blocking

Proteins are classified into the chemokine family based on their structural characteristics, not just their ability to attract cells. All chemokines are small, with a molecular mass of between 8 and 10 kDa. They are approximately 20-50% identical to each other; that is, they share gene sequence and amino acid sequence homology. They all also possess conserved amino acids that are important for creating their 3-dimensional or tertiary structure, such as (in most cases) four cysteines that interact with each other in pairs to create a Greek key shape that is a characteristic of chemokines. Intramolecular disulfide bonds typically join the first to third, and the second to fourth cysteine residues, numbered as they appear in the protein sequence of the chemokine. Typical chemokine proteins are produced as pro-peptides, beginning with a signal peptide of approximately 20 amino acids that gets cleaved from the active (mature) portion of the molecule during the process of its secretion from the cell. ...

Use of cell adhesion inhibitor for the mobilization of antigen presenting cells and immune cells in a cell mixture (AIM) from the peripheral blood and methods of use - Disclosed is a method to recover an antigen presenting cells (APCs) and immune cells rich mixture (AIM) from peripheral blood mononuclear cells (PBMC) mobilized with one or more cell adhesion inhibitors for the preparation of an AIM vaccine or an AIM adoptive immunotherapy preparation. In addition, AIM mobilization can be enhanced by priming, simultaneously or in sequence, one or more of a combination of different chemical compounds, cytokines, hormones, growth factors, etc. The interaction of chemokines and chemokine receptors enable tumor cells attachment or in close proximity to antigen presenting cells and immune cells which possess similar receptors in a micro niche environment. Severing the chemokine/chemokine receptor linkage by a cell adhesion inhibitor will release these specifically primed cell mixtures into the ...

Our results showed that poly(I:C), a TLR3 agonist, up-regulated the production of inflammatory cytokines/chemokines such as MIP1-α, MIP1-β, RANTES, IL-6, and IL-8, by activating NFκB. Incubation of HCECs with poly(I:C) also activated IRF3 followed by IFN-β production. The up-regulated expression of TLR 3 by poly(I:C) indicates that the TLR3/TRIF signaling pathways were most likely activated by poly(I:C) in HCECs. This is consistent with previous reports [1,15-17]. The cytokines and chemokines investigated are known to have powerful effects in recruiting immune cells and stimulating the maturation of dendritic cells [29-31]. Therefore, we suggest that corneal epithelial cells, when the TLR3s are activated de novo, are able to recruit and activate immune cells against viral infections. Our results showed that DEX and CsA inhibit the poly(I:C)-induced NFκB activation and the subsequent production of inflammatory cytokines/chemokines. Earlier studies have shown that the concentration of ...

A number of the investigative efforts on chemokines have focused on intracellular signaling. Data from studies indicate that stimulation of chemokine receptors results in the activation of a variety of effector molecules.

AU - Westwick, John. PY - 1996. Y1 - 1996. N2 - 1. Rheumatoid arthritis is associated with the accumulation and activation of selected populations of inflammatory cells within the arthritic joint. One putative signal for this process is the production, by resident cells, of a group of inflammatory mediators known as the chemokines. 2. The chemokines interleukin-8 (IL-8), monocyte chemotactic protein-1 (MCP-1) and RANTES (regulated on activation normal T-cell expressed and presumably secreted) are target-cell specific chemoattractants produced by synovial fibroblasts in response to stimulation with interleukin-1α (IL-1α) or tumour necrosis factor α (TNFα). The signalling pathways involved in their production are not well defined. We therefore used four different protein kinase C inhibitors to ...

Purpose: : Epithelial cells from several mucosal sites (including conjunctiva) have been shown to actively participate during inflammatory episodes by producing and secreting cytokines and chemokines. The aim of this study was to determine the pattern of cytokines/chemokine secretion from conjunctival epithelial cells under the effect of Th1 and Th2-type cytokines to further clarify the role of conjunctival epithelium in ocular surface inflammation. Methods: : IOBA-NHC (normal human conjunctival) epithelial cells were exposed to Th1- (IFN-γ and TNF-α) or Th2- (IL-4 and IL-13) derived cytokines for 48 h. Time dependency (30 min, 2 h and 24 h) of TNF-α induced cytokine/chemokine secretion was additionally studied. Cytokine/chemokine production was determined in supernatants by a 22-multiplex bead-based assay in a Luminex 100-IS. Additionally, eotaxin-2 and -3 production was analyzed with by ELISA. Results: : After 48 h of Th1 stimulation, cells produced high levels of IL-1α, IL-6, IL8, RANTES ...

This dissertation research explores the molecular aspects of interactions between pro-inflammatory chemokines and the cell surface glycosaminoglycan heparan sulfate. Our goal was to identify the specific attributes of both chemokines and heparan sulfate required for their interactions.. In chapter two, we identified the molecular compositions of heparan sulfate oligosaccharides which bind the CCR2 chemokines MCP-1, -2, and -3. All three chemokines bound to octasaccharides, but not shorter length saccharides. Octasaccharides bearing between 5 and 10 sulfate groups and 0 to 2 acetyl groups were observed to interact with the different chemokines. As indicated by previous studies, increasing sulfation augmented the interactions. Interestingly, our work also identified acetylation as a second factor facilitating binding. The stoichiometry of each formed noncovalent complex was also defined.. In chapter three, we investigated MCP-1: GAG complexes via ion mobility mass spectrometry. Here we uncovered ...

Cells of the innate immune system (monocytes, macrophages, dendritic cells, and natural killer cells) and the adaptive immune system (CD4+ T cells, CD8+ T cells, and B cells) are characterized by the constant mobility from the blood and lymphatic system into and within tissue. Chemokines and their receptors have key roles in the movement of immune cells and are implicated in a wide range of inflammatory diseases involving the central nervous system.7 One chemokine can bind to several receptors, and receptors are sensitive to several ligands.8 C-C chemokine receptor (CCR)1 and CCR2 have been found to be upregulated in CD14+ CD16+ monocytes in patients with neovascular AMD.9 CCR2+ monocyte cells have been shown to infiltrate the subretinal space in the atrophic lesions in donor eyes with GA.4 Further, C-C motif ligand (CCL)2-CCR2 interaction has been implicated in CNV formation.10 The C-X-C motif chemokine receptor (CXCR)3 has important inhibitory functions in angiogenesis and has been found to be ...

Link to Pubmed [PMID] - 23696662. Proc. Natl. Acad. Sci. U.S.A. 2013 Jun;110(23):9475-80. CC chemokine receptor 5 (CCR5) is a receptor for chemokines and the coreceptor for R5 HIV-1 entry into CD4(+) T lymphocytes. Chemokines exert anti-HIV-1 activity in vitro, both by displacing the viral envelope glycoprotein gp120 from binding to CCR5 and by promoting CCR5 endocytosis, suggesting that they play a protective role in HIV infection. However, we showed here that different CCR5 conformations at the cell surface are differentially engaged by chemokines and gp120, making chemokines weaker inhibitors of HIV infection than would be expected from their binding affinity constants for CCR5. These distinct CCR5 conformations rely on CCR5 coupling to nucleotide-free G proteins ((NF)G proteins). Whereas native CCR5 chemokines bind with subnanomolar affinity to (NF)G protein-coupled CCR5, gp120/HIV-1 does not discriminate between (NF)G protein-coupled and uncoupled CCR5. Interestingly, the antiviral activity ...

However, what regulates myometrial chemokine expression and whether the increase in expression precedes the onset of labor, and so may have a role in its causation, or occurs after, and is simply a consequence of labor, is uncertain. Therefore, we assessed 1) chemokine expression in nonlaboring and laboring myometrial samples obtained at and before term and 2) the factors that regulate myometrial chemokine expression. We found that term labor was characterized by an increase in CXCL8 and CCL2 in both upper and lower segments, whereas PTL ...

The purpose of this study was to determine whether certain chemokines, which are highly expressed in injured skeletal muscle, are involved in the repair and functional recovery of the muscle after traumatic injury.

Flagellin and LPS induced the expression of a number of other chemokines. The neutrophil-active chemokines GRO-α, GRO-β, GRO-γ, and IL-8 were expressed in both LPS- and fliC-treated DCs, as were the monocyte/macrophage/NK-active chemokines MCP-1, MIP-1α, MIP-1β, and RANTES. These findings suggest that DCs not only play a role in the initiation of an acquired immune response, but that they may also play a role in amplifying the early immune response by participating in the trafficking of innate immune cells to sites of infection. The early expression of these chemokines (1-3 h) is consistent with the notion that iDCs, upon encounter with pathogens, express these chemokines before the expression of the lymph node homing chemokine receptor CCR7, which is maximally expressed at 24 h after stimulation (Fig. 2⇑B).. Another intriguing finding was that murine splenic DCs do not mature to purified bacterial flagellin. Besides providing a control for the purity of our fliC preparation, this seems ...

Some chemokines are produced by leukocytes and other cells in response to external stimuli and are involved in inflammatory reactions, and other chemokines are produced constitutively in tissues and play a role in tissue organization. Chemokines were discovered on the basis of their activity as leukocyte chemoattractants, and this action is the main basis of their functional roles.. • Chemokines are essential for the recruitment of circulating leukocytes from blood vessels into extravascular sites. Leukocyte recruitment, including naive lymphocytes entering lymph nodes through high endothelial venules and effector lymphocytes, monocytes, and neutrophils entering into tissue sites of infection, is regulated by the actions of several chemokines. Che-mokines produced in the tissues bind to heparan sulfate proteoglycans on endothelial cells that line postcapillary venules and are displayed in this way to circulating leukocytes that have bound to the endo-thelial surfaces through adhesion molecule ...

Chemokines are small immune system proteins mediating leukocyte migration and activation, and are important in many aspects of health and diseases. Some chemokines also have the ability to block HIV-1 infection by binding to the HIV-1 co-receptors CCR5 (CC chemokine receptor 5) and CXCR4 (CXC chemokine receptor 4). The first part of this work is to determine the mechanism of action of a human herpesvirus-8 encoded viral chemokine analog vMIP-II (viral macrophage inflammatory protein-II) by characterizing its interactions with endothelial surface glycosaminoglycans (GAGs) and cell surface receptors. Nuclear magnetic resonance (NMR), mutagenesis and molecular-docking were conducted and results show that vMIP-II tightly binds glycosaminoglycans using residues distributed along one face of the protein, such as R18, R46 and R48, and that there is a shift in the GAG binding site between the monomer and dimer form of vMIP-II where the N-terminus is involved in GAG binding for the dimer. This study, for ...

BACKGROUND: Both keratinocytes and T-cells are crucial players in cutaneous immune responses. We hypothesized that direct interactions between keratinocytes and T-cell subsets could shape the nature or strength of the local immune response. OBJECTIVE: We investigated direct interactions between keratinocytes and T-cell subsets, focused on keratinocyte chemokine production and T-cell phenotype and cytokine production. METHODS: A newly developed in vitro serum free co-culture model using primary keratinocytes and T-cells subsets from healthy human donors was used. Keratinocyte chemokine production was analyzed with luminex, T-cell phenotype and cytokine production were analyzed with flow cytometry. RESULTS: Our data show that upon co-culture with CD4(pos) or CD8(pos) T-cells primary human keratinocytes increased production of functionally active chemokines CCL2, CCL20 and CXCL10 and that regulatory T-cells did not regulate keratinocyte chemokine production. Next to that, we found that ...

Chemokines are believed to play a crucial role in local immunoresponse by regulating leukocyte movement in various tissues, including the intestinal mucosa. It has been suggested that they are key players in cancer biology, and several studies have identified leukocyte infiltration as a hallmark of most cancers. The chemokines CCL17 and CCL22 attract CCR4-bearing cells, which are especially polarised to Th2-type cells and regulatory T cells (Treg). Recent studies have revealed the participation of the CCL17 and CCL22 proteins in diseases such as atopic dermatitis and lymphoma. The purpose of this study was to assess the role of CCL17 and CCL22 protein expression in colorectal cancer (CRC) and to ascertain whether an association exists between promoter -431C,T CCL17 and -961G,A CCL22 gene polymorphisms in CRC versus non-CRC subjects. Using the ELISA assay, we noted a significantly higher expression of CCL22 in tumour tissue with a 2.3-fold up-regulation (tumour vs. paired normal tissue, n=78) but ...

The chemokines ELC2 (also called MIP-3β) and SLC (also called 6Ckine), and their cognate receptor, CCR7, have profound effects on the regulation of dendritic cells (DC) and T cells. ELC and SLC have been shown to be major attractants of mature (although not immature) DC, and they have been suggested to control the migration of the newly postulated T central memory lymphocytes. Natural or targeted genetic deletions of ELC, SLC, or CCR7 result in marked deficiencies in DC, T and B cell trafficking, as well as morphological disruption of secondary lymphoid organ architecture (1, 2, 3, 4, 5, 6, 7). CCR7 is related to another chemokine receptor, CCR9 (formerly the orphan clone GPR9.6), shown to be a receptor for the CC chemokine TECK (8, 9). The CCR9/TECK pairing has been reported to be important for the regulation of thymocytes, as well as lymphocytes with intestine-targeted homing patterns (10). To date, CCR9 has been the only reported TECK receptor and CCR7 the only credible receptor for ELC and ...

C-C chemokine receptor type 10 is a protein that in humans is encoded by the CCR10 gene. Chemokines are a group of small (approximately 8 to 14 kD), mostly basic, structurally related molecules that regulate cell trafficking of various types of leukocytes through interactions with a subset of 7-transmembrane, G protein-coupled receptors. Chemokines also play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis. Chemokines are divided into 2 major subfamilies, CXC and CC, based on the arrangement of the first 2 of the 4 conserved cysteine residues; the 2 cysteines are separated by a single amino acid in CXC chemokines and are adjacent in CC chemokines. CCR10 is a chemokine receptor. Its ligands are CCL27 and CCL28. This receptor is normally expressed by melanocytes, plasma cells and skin-homing T cells. B16 melanoma cell transduction ...

For several years, it has been known that stimulation with bacterial LPS protects macrophages from productive infection by HIV-1 in vitro ((15), (16)). Despite the potential implications of this finding for the pathogenesis and treatment of HIV infection, the mechanisms responsible for the HIV suppressive effect of LPS have remained unknown. Our present results indicate that LPS stimulates human MDM to release soluble factors, the C-C chemokines RANTES, MIP-1α, and MIP-1β, that strongly inhibit HIV replication, not only in macrophages but also in T lymphocytes.. These data may help redefine our current understanding of the role played by monocyte/macrophages in the pathogenesis of HIV infection. Macrophages have been viewed mostly negatively, as major targets for infection ((3), (4)), reservoirs for the virus ((1), (2)), triggers for T cell apoptosis ((36), (37)), and last but not least, as a source of soluble factors (TNF-α, IL-1, IL-6) that sustain viral replication ((27), (38), (39)). The ...

Toll-like receptor 2 (TLR2) is implicated in various pathologies, mainly in terms of its function within innate immune cells. However, TLR2 is also present in endothelial cells. Here, we explored the physiological and pathophysiological roles of endothelial TLR2 signaling. We found that TLR2 was highly abundant in the endothelium within various tissues using TLR2-IRES-EGFP reporter mice and was required for proinflammatory endothelial cell function. Endothelial cells lacking TLR2 exhibited reduced proinflammatory potential at the protein, cell, and tissue levels. Loss of endothelial TLR2 blunted the inflammatory response to both exogenous and endogenous danger signals in endothelial cells in culture and in vivo. Endothelial TLR2 promoted tumor growth, angiogenesis, and protumorigenic immune cell recruitment in a mouse model of prostate cancer. Furthermore, the cell surface localization of P-selectin and the subsequent production of other critical cell adhesion molecules (such as E-selectin, ...

The relation of cancer and the immune system has been traditionally regarded in terms of war; a force of courageous immune system soldiers representing, lets say, The United States of Your Body facing the evil forces of anarchy in the form of tumoral cells. Following this logic the immune system eradicates tumors (elimination phase) until tumors acquire enough growth rates to compensate the killings (equilibrium phase) and eventually outcompete the immune system (escape phase) 1. However, for the last twenty years there has been a change of paradigm. Now we know that for much killing the immune system inflicts in tumors, tumors use the immune system to grow! A terrifying paradox; the enemy uses our soldiers in its own benefit 2. And how? Well, this is the bad thing of having an enemy from your own body…They know all the dirty tricks. Let´s go down to details; let´s talk about chemokines. Chemokines are small proteins that attract (among other cell types) immune cells expressing specific ...

Despite the evidence for increased SM inflammation in obesity, the underlying mechanisms remain largely unexamined. Below, we detail potential roles for various mediators in SM inflammation.. Chemokines, adhesion molecules, and immune cell infiltration. Similar to what is observed in visceral AT (61, 74, 75), inflammation, including immune cell infiltration, starts early in SM during obesity development (35, 53, 56, 57, 60). Macrophage infiltration precedes T cell infiltration (35). Infiltration of leukocytes from the circulation into tissues requires attractant signals such as chemokines, and chemokines such as MCP-1 increase early in SM and visceral AT of mice fed a HFD. In visceral AT, the increase in MCP-1 appears to precede the increases in macrophages and the activation marker TNF-α (74, 75), suggesting that the initial increase in chemokines may derive from tissue-resident cells. Adipocytes and myocytes, the main resident cells in AT and SM, respectively, can express chemokines including ...

Our long term goal is to understand the mechanisms that lead to chronic inflammation. Acute inflammation is a healthy response to infection or trauma. In contrast, chronic inflammation leads to, or exacerbates, most disease states. The process of acute inflammation has a initiation, maintainence and resolution phase. Either persitent initiation, or lack of resolution of acute inflammation can lead to a chronic activation of the immune system. To understand the genetic, epigenetic and environmental factors we use both mouse models and human studies employing both computational and laboratory tools. Osteoimmunology: Osteoimmunology is the emerging field of the crosstalk between the immune and skelatal systems. Osteoclasts are bone resorbing cells, derived from the myeloid cell lineage, that play a key role in remodeling and maintaining bone density. We discovered that osteoclasts produce chemokines that recruit T-cells and act as antigen-presenting cells to the CD8 T-cells. Cross-presentation of ...

The purpose of the innate immunity system is to keep away all pathogens. After, the pathogen makes an appearance in the body, the innate system of defense acts very rapidly. The major point in dealing with the innate system of defense is that it is nonspecific. Therefore, it will approach any pathogen it comes into contact with. The innate systems of defense are very helpful yet we overlook them quite often. The skin is probably the best innate line of defense. It excludes most pathogens from entering the body. Cilia in mucous membranes help sweep out airborne pathogens and dust. Tears, nasal secretions, and saliva are also good because they contain bacteria destroying enzymes. The innate system is also known for phagocytic cells (phago-eating, cyte-cell) which migrate to affected areas and engulfs the pathogens. Phagocytic cells include: Neutrophils, Macrophages, and Dendritic cells that are part of the white blood cell fraction. Pathogens and infected cells produce chemokines, peptides ...

The precise role of CD26/DPP4 in tumor biology is unclear at this time. Preclinical studies have shown conflicting data with differential CD26/DPP4 expression and activity depending on the type of cancer. These studies suggest that it has a role as either a tumor suppressor or tumor activator depending on the tumor microenvironment and molecules with which CD26/DPP4 associates (1,3). However, since most of these studies involved in vitro assays, further investigations with in vivo experiments are needed to definitively establish the role of CD26/DPP4 in each cancer type.. Published studies have demonstrated that CD26/DPP4 plays a major role in the invasion and metastasis of selected cancers, and may be a novel therapeutic target (1,2,5,6). There are several suggested mechanisms for cancer metastasis involving the intrinsic peptidase activity of CD26/DPP4 and its subsequent chemokine regulation, as well as its ability to bind key molecules. For example, CD26/DPP4 can upregulate the expression of ...

My research focus is in immunosenescence and the effects of inflammation in aging. There are 3 ongoing research projects:. 1. The effects of early life micronutrients on chronic inflammatory disease development. This NIH/NIA-sponsored program examines how prenatal micronutrient alters the susceptibility to chronic inflammatory and autoimmune disease development in the F1 generation through the epigenetic system. The first part of this work has just been accepted for publication in the Journal of Nutrition, with Colin as the lead/first author. We are currently examining the mechanisms and effect of the pre-natal diet on cardiovascular disease, lupus and rheumatoid arthritis development.. 2. Age-related obesity and inflamm-aging. Our earlier work has defined key T cell chemokine changes in murine and human aging, as a mechanism explaining the observation that normal aging is associated with low grade chronic inflammation. In our most recent publication (Nov 2011, J Immunol), in collaboration ...

Up-regulation of certain cytokines and chemokines (signaling molecules involved in the functioning of the immune system) can predict the development of rheumatoid arthritis three years before the onset of symptoms, according to the results of a new study presented today at EULAR 2009, the Annual Congress of the European League Against Rheumatism in Copenhagen, Denmark.

Results Levels of IFNγ and of IFNγ-induced chemokines were markedly elevated during active MAS and sec-HLH and were significantly higher in patients with MAS compared with active sJIA without MAS. Levels in patients with active sJIA without MAS were comparable to those of patients with clinically inactive sJIA. During MAS, ferritin and alanine transferase levels and neutrophil and platelet counts were significantly correlated with serum levels of IFNγ and CXCL9. In murine MAS, serum levels of ferritin were significantly correlated with mRNA levels of Cxcl9 in liver and spleen. ...

Chemokine Receptors: 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.

This binding between an integrin and its partner ligand (expressed on the blood vessel wall) is strong enough to fully arrest the immune cells, which can then squeeze through the gaps in between the cells that make up the walls of the blood vessel.. The final piece of the puzzle that you need to understand is what causes the activation of the integrin. Chemical signals called chemokines are produced by inflammed tissues, and these chemokines interact with receptors on the immune cells, telling them to extend their integrins in order to dock onto the vessel wall.. To recap: cells lining the blood vessel express selectins that bind sugars on immune cells, slowing them down and letting them roll along the vessel wall. Chemokines then signal to the immune cells that its time to activate their integrins, which can then grab tightly to the vessel wall, allowing the cell to stop and migrate across and into the tissue.. What I havent mentioned yet is that there are many different kinds of selectins, ...

This antimicrobial gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. Similar to other chemokines the protein encoded by this gene inhibits hemopoiesis and stimulates chemotaxis. This protein is chemotactic in vitro for thymocytes and activated T cells, but not for B cells, macrophages, or neutrophils. The cytokine encoded by this gene may also play a role in mediating homing of lymphocytes to secondary lymphoid organs. It is a high affinity functional ligand for chemokine receptor 7 that is expressed on T and B lymphocytes and a known receptor for another member of the cytokine family (small inducible cytokine A19).

Immune cells constantly circulate in the body in search of pathogens or tissue damage. Because they move autonomously, immune cell trafficking must be tightly controlled and coordinated by extracellular cues. The main signals that guide immune cells are chemokines, small polypeptides that modulate the migratory behavior of cells. Remarkably, most chemokines are not only sensed but also secreted by immune cells, indicating that immune cells might either attract more of their own kind or trigger complex patterns of feedbacks between different cell populations. Such cascades might allow different immune cell types to orchestrate their sequential arrival at a site of infection (1). On page 1071 of this issue, Lim et al. (2) show that this is indeed the case with neutrophils and cytotoxic T cells, the former leaving a trail of cues for the latter to follow during the eradication of a viral infection. ...

The role of NK cells in solid tumors and especially in CRC is not well understood, specifically whether NK cells also contribute to an immune surveillance (16). For CRC, high densities of infiltrating lymphocytes, high levels of CD3, GrmB, CXCL8, an IFN-γ/IRF1-driven Th1 response and low angiogenesis were shown to have a strong prognostic impact (17, 18). Since most of the above parameters are also expressed or produced by NK cells, we aimed to delineate the contribution of NK cells to these observations. Our results, therefore, could be interpreted in different aspects: (a) the infiltration of NK cells following treatment is a possible predictive marker; (b) migration of NK cells into tumor needs to be an aim of clinical trials, regardless of the stage of the disease; (c) simple administration of a single cytokine/chemokine is unlikely to yield NK migration and clinical benefit; and (d) cytokines/chemokine levels are lower in metastatic lesions (and cannot be compared to the primary tumor) and ...
