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.T-Lymphocytes: Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER).

Many variations of the method have been developed.Flow Cytometry: 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.

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.

A functional, discontinuous HIV-1 gp120 C3/C4 domain-derived, branched, synthetic peptide that binds to CD4 and inhibits MIP-1alpha chemokine binding. (1/1033)

This paper describes a branched synthetic peptide [3.7] that incorporates sequence discontinuous residues of HIV-1 gp120 constant regions. The approach was to bring together residues of gp120 known to interact with human cell membranes such that the peptide could fold to mimic the native molecule. The peptide incorporates elements of both the conserved CD4 and CCR5 binding sites. The 3.7 peptide, which cannot be produced by conventional genetic engineering methods, is recognized by antiserum raised to native gp120. The peptide also binds to CD4 and competitively inhibits binding of QS4120 an antibody directed against the CDR2 region of CD4. When preincubated with the CD4+ve MM6 macrophage cell line, which expresses mRNA for the CCR3 and CCR5 chemokine receptors, both 3.7 and gp120 inhibit binding of the chemokine MIP-1alpha. The peptide also inhibits infection of primary macrophages by M-tropic HIV-1. Thus, 3.7 is a prototype candidate peptide for a vaccine against HIV-1 and represents a novel approach to the rational design of peptides that can mimic complex sequence discontinuous ligand binding sites of clinically relevant proteins.  (+info)

Induction of macrophage C-C chemokine expression by titanium alloy and bone cement particles. (2/1033)

Particulate wear debris is associated with periprosthetic inflammation and loosening in total joint arthroplasty. We tested the effects of titanium alloy (Ti-alloy) and PMMA particles on monocyte/macrophage expression of the C-C chemokines, monocyte chemoattractant protein-1 (MCP-1), monocyte inflammatory protein-1 alpha (MIP-1alpha), and regulated upon activation normal T expressed and secreted protein (RANTES). Periprosthetic granulomatous tissue was analysed for expression of macrophage chemokines by immunohistochemistry. Chemokine expression in human monocytes/macrophages exposed to Ti-alloy and PMMA particles in vitro was determined by RT-PCR, ELISA and monocyte migration. We observed MCP-1 and MIP-1alpha expression in all tissue samples from failed arthroplasties. Ti-alloy and PMMA particles increased expression of MCP-1 and MIP-1alpha in macrophages in vitro in a dose- and time-dependent manner whereas RANTES was not detected. mRNA signal levels for MCP-1 and MIP-1alpha were also observed in cells after exposure to particles. Monocyte migration was stimulated by culture medium collected from macrophages exposed to Ti-alloy and PMMA particles. Antibodies to MCP-1 and MIP-1alpha inhibited chemotactic activity of the culture medium samples. Release of C-C chemokines by macrophages in response to wear particles may contribute to chronic inflammation at the bone-implant interface in total joint arthroplasty.  (+info)

Differential regulation of eosinophil chemokine signaling via CCR3 and non-CCR3 pathways. (3/1033)

To investigate eosinophil stimulation by chemokines we developed a sensitive assay of leukocyte shape change, the gated autofluorescence/forward scatter assay. Leukocyte shape change responses are mediated through rearrangements of the cellular cytoskeleton in a dynamic process typically resulting in a polarized cell and are essential to the processes of leukocyte migration from the microcirculation into sites of inflammation. We examined the actions of the chemokines eotaxin, eotaxin-2, monocyte chemoattractant protein-1 (MCP-1), MCP-3, MCP-4, RANTES, macrophage inflammatory protein-1alpha (MIP-1alpha), and IL-8 on leukocytes in mixed cell suspensions and focused on the responses of eosinophils to C-C chemokines. Those chemokines acting on CCR3 induced a rapid shape change in eosinophils from all donors; of these, eotaxin and eotaxin-2 were the most potent. Responses to MCP-4 were qualitatively different, showing marked reversal of shape change responses with agonist concentration and duration of treatment. In contrast, MIP-1alpha induced a potent response in eosinophils from a small and previously undescribed subgroup of donors via a non-CCR3 pathway likely to be CCR1 mediated. Incubation of leukocytes at 37 degrees C for 90 min in the absence of extracellular calcium up-regulated responses to MCP-4 and MIP-1alpha in the majority of donors, and there was a small increase in responses to eotaxin. MIP-1alpha responsiveness in vivo may therefore be a function of both CCR1 expression levels and the regulated efficiency of coupling to intracellular signaling pathways. The observed up-regulation of MIP-1alpha signaling via non-CCR3 pathways may play a role in eosinophil recruitment in inflammatory states such as occurs in the asthmatic lung.  (+info)

Effects of dexamethasone and ibuprofen on LPS-induced gene expression of TNF alpha, IL-1 beta, and MIP-1 alpha in rat lung. (4/1033)

AIM: To study the kinetics of tumor necrosis factor alpha (TNF alpha), interleukine-1 (IL-1 beta), and macrophage inflammatory protein-1 alpha (MIP-1 alpha) gene expression in rat lung after i.p. lipopolysaccharides (LPS) and the effect of dexamethasone (Dex) and ibuprofen (Ibu) on the cytokines gene expression. METHODS: The amount of Evans blue in lung was measured by fluorescence method. The mRNA levels of TNF alpha, IL-1 beta, and MIP-1 alpha in rat lung were assessed by slot blot analysis. RESULTS: The mRNA levels of TNF alpha, IL-1 beta, and MIP-1 alpha in rat lung after i.p. LPS increased in a dose-dependent manner, and peaked at 2, 6, and 12 h, respectively. Both Dex 50 mg.kg-1 and Ibu 90 mg.kg-1 injected at 1 h before i.p. LPS markedly decreased the content of Evans blue in lung at 1 h after i.p. LPS. After Dex or Ibu pretreatment, the peak levels of TNF alpha, IL-1 beta, and MIP-1 alpha mRNA decreased markedly compared with LPS alone. CONCLUSION: The gene expression of TNF alpha, IL-1 beta, and MIP-1 alpha in rat lung increased after i.p. LPS. Dex and Ibu prevented LPS-induced lung injury through inhibiting the cytokines gene expression.  (+info)

Intracellular adhesion molecule-1 modulates beta-chemokines and directly costimulates T cells in vivo. (5/1033)

The potential roles of adhesion molecules in the expansion of T cell-mediated immune responses in the periphery were examined using DNA immunogen constructs as model antigens. We coimmunized cDNA expression cassettes encoding the adhesion molecules intracellular adhesion molecule-1 (ICAM-1), lymphocyte function associated-3 (LFA-3), and vascular cell adhesion molecule-1 (VCAM-1) along with DNA immunogens, and we analyzed the resulting antigen-specific immune responses. We observed that antigen-specific T-cell responses can be enhanced by the coexpression of DNA immunogen and adhesion molecules ICAM-1 and LFA-3. Coexpression of ICAM-1 or LFA-3 molecules along with DNA immunogens resulted in a significant enhancement of T-helper cell proliferative responses. In addition, coimmunization with pCICAM-1 (and more moderately with pCLFA-3) resulted in a dramatic enhancement of CD8-restricted cytotoxic T-lymphocyte responses. Although VCAM-1 and ICAM-1 are similar in size, VCAM-1 coimmunization did not have any measurable effect on cell-mediated responses. These results suggest that ICAM-1 and LFA-3 provide direct T-cell costimulation. These observations are further supported by the finding that coinjection with ICAM-1 dramatically enhanced the level of interferon-gamma (IFN-gamma) and beta-chemokines macrophage inflammatory protein-1alpha (MIP-1alpha), MIP-1beta, and regulated on activation normal T-cell expression and secreted (RANTES) produced by stimulated T cells. Through comparative studies, we observed that ICAM-1/LFA-1 T-cell costimulatory pathways are independent of CD86/CD28 pathways and that they may synergistically expand T-cell responses in vivo.  (+info)

Tyrosine sulfation of the amino terminus of CCR5 facilitates HIV-1 entry. (6/1033)

Chemokine receptors and related seven-transmembrane-segment (7TMS) receptors serve as coreceptors for entry of human and simian immunodeficiency viruses (HIV-1, HIV-2, and SIV) into target cells. Each of these otherwise diverse coreceptors contains an N-terminal region that is acidic and tyrosine rich. Here, we show that the chemokine receptor CCR5, a principal HIV-1 coreceptor, is posttranslationally modified by O-linked glycosylation and by sulfation of its N-terminal tyrosines. Sulfated tyrosines contribute to the binding of CCR5 to MIP-1 alpha, MIP-1 beta, and HIV-1 gp120/CD4 complexes and to the ability of HIV-1 to enter cells expressing CCR5 and CD4. CXCR4, another important HIV-1 coreceptor, is also sulfated. Tyrosine sulfation may contribute to the natural function of many 7TMS receptors and may be a modification common to primate immunodeficiency virus coreceptors.  (+info)

Secretion of beta-chemokines by bronchoalveolar lavage cells during primary infection of macaques inoculated with attenuated nef-deleted or pathogenic simian immunodeficiency virus strain mac251. (7/1033)

Primary infection of macaques with simian immunodeficiency virus (SIV) as a model of human immunodeficiency virus (HIV) infection represents a unique opportunity to investigate early lentivirus-host interactions. In order to gain insight into immunopathogenic events taking place in the lung during lentiviral infection, we analysed lymphocyte expansion in the lung and chemokine secretion by mononuclear cells obtained by bronchoalveolar lavage (BALMCs) during primary infection by a pathogenic and a non-pathogenic SIV. Two groups of cynomolgus macaques were inoculated intravenously with a fully pathogenic isolate of SIVmac251 or with an attenuated, nef-deleted, molecular clone of SIVmac251. Spontaneous MIP-1alpha, MIP-1beta and RANTES production was assessed by ELISA in supernatants of short-term cultured BALMCs. Kinetics of haematological, virological and immunological parameters were investigated simultaneously. All 11 inoculated animals became infected. Monkeys inoculated with the nef-deleted SIV clone exhibited a significantly reduced plasma virus load and a less pronounced accumulation of lymphocytes in the lung compared to monkeys infected with the pathogenic SIVmac251 isolate. Compared to pre-infection levels, we observed an increase in the levels of RANTES, MIP1-alpha and MIP1-beta production in the two groups of monkeys, by the time of peak viraemia. Strikingly, a greater enhancement of RANTES and MIP-1alpha production was detected in monkeys infected with the attenuated virus. Given the potential influence of beta-chemokines on the immune response and virus replication, such results suggest that RANTES, MIP1-alpha and MIP1-beta could contribute to the singular features of the immune response elicited during infection of macaques with an attenuated SIV.  (+info)

Specific activation of leukocyte beta2 integrins lymphocyte function-associated antigen-1 and Mac-1 by chemokines mediated by distinct pathways via the alpha subunit cytoplasmic domains. (8/1033)

We show that CC chemokines induced a sustained increase in monocyte adhesion to intercellular adhesion molecule-1 that was mediated by Mac-1 (alphaMbeta2) but not lymphocyte function-associated antigen-1 (LFA-1; alphaLbeta2). In contrast, staining for an activation epitope revealed a rapid and transient up-regulation of LFA-1 activity by monocyte chemotactic protein-1 (MCP-1) in monocytes and Jurkat CCR2 chemokine receptor transfectants or by stromal-derived factor-1alpha in Jurkat cells. Differential kinetics for activation of Mac-1 (sustained) and LFA-1 (transient) avidity in response to stromal-derived factor-1alpha were confirmed by expression of alphaM or alphaL in alphaL-deficient Jurkat cells. Moreover, expression of chimeras containing alphaL and alphaM cytoplasmic domain exchanges indicated that alpha cytoplasmic tails conferred the specific mode of regulation. Coexpressing alphaM or chimeras in mutant Jurkat cells with a "gain of function" phenotype that results in constitutively active LFA-1 demonstrated that Mac-1 was not constitutively active, whereas constitutive activity was mediated via the alphaL cytoplasmic tail, implying the presence of distinct signaling pathways for LFA-1 and Mac-1. Transendothelial chemotaxis of monocytes in response to MCP-1 was dependent on LFA-1; however, Mac-1 was involved at MCP-1 concentrations stimulating its avidity, showing differential contributions of beta2 integrins. Our data suggest that a specific regulation of beta2 integrin avidity by chemokines may be important in leukocyte extravasation and may be triggered by distinct activation pathways transduced via the alpha subunit cytoplasmic domains.  (+info)

Macrophage Inflammatory Proteins (MIP) belong to the family of chemotactic cytokines known as chemokines. In humans, there are two major forms, MIP-1α and MIP-1β that are now officially named CCL3 and CCL4, respectively. Both are major factors produced by macrophages after they are stimulated with bacterial endotoxins. They are crucial for immune responses towards infection and inflammation. They activate human granulocytes (neutrophils, eosinophils and basophils) which can lead to acute neutrophilic inflammation. They also induce the synthesis and release of other pro-inflammatory cytokines such as interleukin 1 (IL-1), IL-6 and TNF-α from fibroblasts and macrophages. The genes for CCL3 and CCL4 are both located on human chromosome 17. They are produced by many cells, particularly macrophages, dendritic cells, and lymphocytes. MIP-1 are best known for their chemotactic and proinflammatory effects but can also promote homoeostasis. Biophysical analyses and mathematical modelling has shown ...

bacillus Calmette-Guérin (BCG) vaccine. The present study evaluated the release of cytokines [interleukin (IL)-1, tumour necrosis factor and IL-6] and chemokines [macrophage inflammatory protein (MIP)-1α and MIP-1β] by THP-1 derived macrophages infected with BCG vaccine obtained by growing mycobacteria in Viscondessa de Moraes Institute medium medium (oral) or Sauton medium (intradermic) to compare the effects of live and heat-killed (HK) mycobacteria. Because BCG has been reported to lose viability during the lyophilisation process and during storage, we examined whether exposing BCG to different temperatures also triggers differences in the expression of some important cytokines and chemokines of the immune response. Interestingly, we observed that HK mycobacteria stimulated cytokine and chemokine production in a different pattern from that observed with live mycobacteria ...

The capacity of DCs to reach the site of injury/infection and consequently to initiate immunity is determined by their ability to respond to selected chemokines. In this study, we show that MIP-3α is a major chemokine produced by activated epithelial cells, and selectively active on LCs and their precursors. MIP-3αs unique activity suggests that it plays a key role in the control of LC recruitment at inflamed epithelial surfaces and in the regulation of epithelial immunity.. Among all CC chemokines tested, MIP-3α appears to be the most potent chemokine inducing the migration of LC precursors and freshly isolated LCs but not of any other DC population. This result is in line with the specific expression of CCR6 by cells of the LC lineage in contrast with other receptors such as CCR1, CCR2, and CCR5 that are expressed on several other DC populations ((9)(34); and Caux, C., manuscript in preparation). This observation is in accordance with previous reports showing that both CCR6 expression and ...

Blocking HIV-1 cell entry has long been a major goal of anti-HIV drug development. Here, we report a successful design of two highly potent chimeric HIV entry inhibitors composed of one CCR5-targeting RANTES (regulated on activation normal T cell expressed and secreted) variant (5P12-RANTES or 5P14-RANTES (Gaertner, H., Cerini, F., Escola, J. M., Kuenzi, G., Melotti, A., Offord, R., Rossitto-Borlat, I., Nedellec, R., Salkow-itz, J., Gorochov, G., Mosier, D., and Hartley, O. (2008) Proc. Natl. Acad. Sci. U.S.A. 105, 17706 -17711)) linked to a gp41 fusion inhibitor, C37. Chimeric inhibitors 5P12-linker-C37 and 5P14-linker-C37 showed extremely high antiviral potency in single cycle and replication-competent viral assays against R5-tropic viruses, with IC50 values as low as 0.004 nM. This inhi-bition was somewhat strain-dependent and was up to 100-fold better than the RANTES variant alone or in combination with unlinked C37. The chimeric inhibitors also fully retained the antiviral activity of C37 ...
MIP-3 alpha is a CC chemokine that is expressed in the liver, lymph nodes, appendix, PBL and lung and can signal through the CCR6 receptor. MIP-3 alpha is chemotactic towards lymphocytes and dendritic cells. Additionally, it promotes the adhesion of memory CD4+ T cells and inhibits colony formation of bone marrow myeloid immature progenitors. Recombinant human MIP-3 alpha is an 8.0 kDa protein containing 70 amino acid residues, including the four highly conserved cysteine residues present in CC chemokines ...
Thus, it appears that two chemokines, MIP-3α and SDF-1α, are produced constitutively by human keratinocytes, and therefore could both be involved in LC homing to the epidermis. Our findings that SDF-1α does not attract LC precursors (Fig. 1 C) and that these cells also fail to express CXCR4 on their surface (Fig. 6 A) speak against a role of SDF-1α in LC homing. Since ex vivo-purified LCs express CCR2 transcripts (Fig. 5 B), one could argue that this receptor is involved in the attraction of LCs into the epidermis. This is unlikely because (a) resting keratinocytes do not express the CCR2 ligand MCP-1 at the protein level ((33); Fig. 7 E), and (b) LC precursors do not express CCR2 on their surface (Fig. 6 A), and do not migrate in response to MCP-1 (Fig. 1 B). In this context, it is noteworthy that mice genetically manipulated to express MCP-1 in the epidermis have close to normal LC numbers while accumulating dermal DCs and macrophage-like cells (34).. In conclusion, among all the ...

There is emerging evidence that the activation of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) importantly contributes to the up-regulation of a variety of proinflammatory signal transduction pathways and associated genes. Materials and Methods: We tested whether the expression of the chemokines macrophage inflammatory protein (MIP)-1α and MIP-2 are under the control of PARP during inflammation. Results: Pharmacologic inhibition of PARP and genetic deletion of PARP suppressed the expression of MIP-1α and MIP-2 protein and mRNA in immunostimulated cultured murine ...

A cross-sectional study of 100 subjects enrolled in the Multicenter AIDS Cohort Study at the Baltimore site was conducted to measure chemokine production and lymphocyte proliferation by peripheral blood mononuclear cells (PBMC). Statistical analyses of the data revealed that the ...
CCL3 is expressed during experimental GVHD and may be important for the inflammatory response caused by acute GVHD (12, 13). The results reported herewith confirm the relevance of CCL3 in mediating GVHD in mice. Moreover, we report for the first time that blockade of CCL3 with a CBP, evasin-1, which prevents CCL3 function (17), ameliorated GVHD and prevented death. Treatment with evasin-1 prevented the influx of leukocytes, especially CD8+, CD4+ cells and macrophages, to the small intestine and decreased tissue damage in the liver. Mechanistically, inhibition of leukocyte influx to the intestine was due to inhibition by evasin-1 of the ability of leukocytes to adhere to endothelial cells in affected tissues. The latter results suggest that mediation of leukocyte adherence and subsequent migration is the major mechanism by which CCL3 participates in murine GVHD. Finally, the protective effects of evasin-1 against GVHD did not interfere with the beneficial effect of the graft against a leukemic ...
Chemokine (C-C motif) ligand 20 (CCL20) or liver activation regulated chemokine (LARC) or Macrophage Inflammatory Protein-3 (MIP3A) is a small cytokine belonging to the CC chemokine family. It is strongly chemotactic for lymphocytes and weakly attracts neutrophils. CCL20 is implicated in the formation and function of mucosal lymphoid tissues via chemoattraction of lymphocytes and dendritic cells towards the epithelial cells surrounding these tissues. CCL20 elicits its effects on its target cells by binding and activating the chemokine receptor CCR6. Gene expression of CCL20 can be induced by microbial factors such as lipopolysaccharide (LPS), and inflammatory cytokines such as tumor necrosis factor and interferon-γ, and down-regulated by IL-10. CCL20 is expressed in several tissues with highest expression observed in peripheral blood lymphocytes, lymph nodes, liver, appendix, and fetal lung and lower levels in thymus, testis, prostate and gut. The gene for CCL20 (scya20) is located on ...
The primary objective of this study was to examine effects of cocaine on HIV-1 replication in primary CD4+ T cells. suppressing HIV-1 protecting chemokines and/or upregulating the HIV-1 admittance co-receptor [20]C[21]. For example, people of the -chemokine family members that combine to CCR5 such as controlled upon-activation Capital t indicated and 853910-02-8 IC50 secreted (RANTES), macrophage inflammatory proteins 1a (MIP-1a), and MIP-1n possess been proven to inhibit admittance of particular HIV-1 pressures [22]. In addition, proteomics evaluation of cocaine treated PBMCs separated from HIV-positive contributor suggests that cocaine differentially manages appearance of many crucial sponsor aminoacids that may impact HIV-1 duplication [23]. Since these scholarly research had been carried out using cell tradition versions or the combined cell populations of PBMCs, there are no reviews on major Compact disc4+ Capital t cells. Provided that Compact disc4+ Capital t cells are the primary focuses ...
Primary infections of the human cytomegalovirus (HCMV) are followed by a lifelong infection in the state of latency or persistence. It is believed that the virus employs a number of immunomodulatory mechanisms to establish latent infections. Among these are the inhibition of cytotoxic CD8+ T-cells by US11 and the impairment of leukocyte migration by US28. The potency of US11 to mediate the inhibition of T-cell activation was analysed in a model of MHC class I mediated T-cell activation. Surface expression of MHC class I molecules was reduced by 60 % after expression of US11 in murine dendritic cells. In contrast, there was no reduction in the capacity of the dendritic cells to induce T-cell proliferation. The US28 gene product has been characterized as a functional receptor for the inflammatory chemokines RANTES, MCP-1, MCP-3, MIP-1?? MIP-1? and fractalkine.Upon ligand stimulation US28 mediates the activation of MAPK and additionally a constitutive activation of NF-?B. By generating site ...

Leukocyte recruitment is a key feature in ischemiaâ€"reperfusion (I/R)-induced tissue injury. The aim of the present study was to investigate the effect of Rho-kinase inhibition on I/R-provoked leukocyte recruitment in the colon. C57BL/6 mice were subjected to 30 min of ischemia by clamping of the superior mesenteric artery followed by 120 min of reperfusion. Intraperitoneal pretreatment with the selective Rho-kinase inhibitors fasudil (4â€"40 mg/kg) and Y-27632 (1â€"10 mg/kg) was administered prior to induction of colonic I/R. Leukocyteâ€"endothelium interactions were analyzed by intravital fluorescence microscopy. Colonic content of tumour necrosis factor-α (TNF-α) and the CXC chemokines macrophage inflammatory protein-2 (MIP-2) and cytokine-induced neutrophil chemoattractant (KC) were determined by ELISA. Additionally, colonic activity of myeloperoxidase (MPO), a marker of leukocyte infiltration, and malondialdehyde (MDA), were quantified. Fasudil and Y-27632 pretreatment ...
Macrophages are an important source of pro-inflammatory and pro-angiogenic factors, which can promote pathological processes involving inflammation and angiogenesis. This study investigated the effects of Apelin on macrophages under both normal and hypoxic conditions. Under normal culture conditions, Apelin down-regulated the mRNA expression levels of monocyte chemotactic protein 1 (MCP1), monocyte chemotactic protein 3 (MCP3), macrophage inflammatory protein 1 (MIP1 alpha, MIP1 beta), vascular endothelial growth factor A (VEGFA), Angiopoietin 2 (Ang2) and tumor necrosis factor alpha (TNF alpha). The supernatant concentrations of MCP1, MCP3, MIP1 alpha, MIP1 beta, macrophage inflammatory protein 2 (MIP2) and TNF alpha proteins were significantly decreased in the Apelin treated group. Hypoxia induced profound up-regulations of the angiogenic, chemokine, and inflammatory factors at both the mRNA and protein levels. Apelin suppressed the hypoxia-induced increases in MCP1, MCP3, MIP2, MIP1 beta and ...

It is known that when naive CD4 T cells recognize an antigen and are activated, they differentiate into 2 subsets having distinct properties of TH1 and TH2 and they are both heterogeneous populations of effector/memory cells [12]. Heterogeneity is a particularly prominent feature of the effector/memory CD4+ T-cell population, which induces subsets capable of producing polarized patterns of cytokines that serve specialized functions and have profound effects on the quality of the immune response [13]. It has recently been learned that, in a new helper T-cell population having characteristics different from TH1 and TH2, IL-23, which is structurally and functionally similar to IL-12, is deeply involved in promotion of differentiation into Th-17 cells that specifically produce IL-17 without producing IFN-γ, IL-4, or IL-13 and also in induction of inflammation and some immunity to infections [14].. Recent studies have suggested that human heterogeneous populations of effector/memory cells display ...

Induction of human sperm chemotaxis is an established phenomenon, though signaling systems physiologically involved have not been identified. Recently, it has been demonstrated that RANTES is present in the follicular fluid and that this molecule is a chemoactractant for human spermatozoa. However, the presence of beta-chemokine receptors on human spermatozoa has never been reported. By cytometric, Western blotting and immunofluorescence analysis, we demonstrate the presence of CCR5 and CCR3 on ejaculated spermatozoa from healthy subjects. CCR5 was detected in the periacrosomal region of the sperm surface, whereas CCR3 was also present in the postacrosomal cap. Individual variability was observed on CCR5 and CCR3 positive sperm percentages. Presence of Delta32+/-) mutation was demonstrated in two subjects expressing CCR5 in half of the ejaculated spermatozoa. Our findings represent the missing information in favor of the possibility that beta-chemokines and their receptors are involved in sperm
Granulomas form by a stepwise series of events, starting when T helper cells recognise protein peptides presented to them by antigen presenting cells bearing histocompatibility class II molecules. Immunological reactivity or inflammation attract monocyte macrophages which fuse to form multinucleated giant cells and onwards to epithelioid cells. Granuloma formation is aided by a cavalcade of chemotactic factors; Th1 cells induce interleukin (IL)-2, interferon gamma, and tumour necrosis factor (TNF) with the help of IL-12 and costimulator B7. The resulting exuberant granuloma formation is associated with active cell mediated hypersensitivity and tissue destruction. This framework is also remodelled by chemokines, adhesion molecules, matrix receptors of the integrin family, costimulators B7 and CD28, IL-12, and RANTES (regulated on activation normal T cells as secreted).. Bronchoalveolar fluid (BALF) reveals this macrophage class II-CD4Th1 cell synergy with its awesome cytokine cascade. Angiotensin ...
The aim of this study was to evaluate some patterns in expression of CC-chemokines (MIP-1alpha, MIP-1beta, MCP-1, RANTES) and their receptors (CCR1, CCR2, CCR3, CCR5) in peripheral blood leukocytes and liver biopsy samples from 21 patients with chronic hepatitis C. 10 healthy subjects were included in the control group. In patients with chronic HCV-infection significant increase of MCP-1 mRNA in liver tissue was observed as the disease progressed. Moreover, content of MCP-1 mRNA was significantly higher in liver as compared with blood. Level of MCP-1 mRNA in liver was directly related with histological changes. Levels of mRNA of CCR1, CCR2, CCR3, and CCR5 in blood of patients with minimal histological manifestations of chronic HCV-infection were significantly lower than in patients with more marked lesions. Expression of CCR1 and CCR5 mRNA in blood was directly correlated with histological activity index and degree of fibrosis. Conducted study demonstrates that progression of chronic hepatitis C is
