In Chinese philosophy and religion, two principles, one negative, dark, and feminine (yin) and one positive, bright, and masculine (yang), from whose interaction all things are produced and all things are dissolved. As a concept the two polar elements referred originally to the shady and sunny sides of a valley or a hill but it developed into the relationship of any contrasting pair: those specified above (female-male, etc.) as well as cold-hot, wet-dry, weak-strong, etc. It is not a distinct system of thought by itself but permeates Chinese life and thought. A balance of yin and yang is essential to health. A deficiency of either principle can manifest as disease. (Encyclopedia Americana)
A parliamentary democracy with a constitutional monarch in southeast Asia, consisting of 11 states (West Malaysia) on the Malay Peninsula and two states (East Malaysia) on the island of BORNEO. It is also called the Federation of Malaysia. Its capital is Kuala Lumpur. Before 1963 it was the Union of Malaya. It reorganized in 1948 as the Federation of Malaya, becoming independent from British Malaya in 1957 and becoming Malaysia in 1963 as a federation of Malaya, Sabah, Sarawak, and Singapore (which seceded in 1965). The form Malay- probably derives from the Tamil malay, mountain, with reference to its geography.

Dysregulated production of interleukin-8 in individuals infected with human immunodeficiency virus type 1 and Mycobacterium tuberculosis. (1/5836)

Interleukin-8 (IL-8) production in vivo was monitored in four study groups: normal blood donors, patients with pulmonary tuberculosis (TB), patients with human immunodeficiency virus type 1 (HIV-1) infection, and dually infected (HIV/TB) patients. We show that whereas there was evidence of detectable levels of cell-associated IL-8 (mRNA and protein) in peripheral cells of healthy individuals, this was largely lost in the disease states studied. Coupled with this finding was significantly increased circulating levels of IL-8 in HIV-1-infected individuals with or without concomitant pulmonary TB (P < 0.001). On the other hand, the capacity of peripheral mononuclear cells to produce IL-8 spontaneously ex vivo was enhanced in HIV-1 and TB patients (P < 0.05) and many of the HIV/TB group, but their corresponding capacities to respond to various stimuli, in particular phytohemagglutinin, were significantly diminished compared to those of normal donors (P < 0.05). Circulating levels of IL-8 in a group of HIV/TB patients were significantly positively correlated with the percentage of polymorphonuclear leukocytes (PMN) in the peripheral circulation (r = 0.65; P = 0.01), the proportions of IL-8 receptor A (IL-8RA)-expressing (r = 0.86; P < 0.01) and IL-8RB-expressing (r = 0.77; P < 0.01) PMN, and the capacity of PMN to migrate in response to IL-8 as chemoattractant (r = 0.68; P < 0. 01). IL-8RB fluorescence intensity, however, was negatively correlated with plasma IL-8 levels (r = -0.73; P < 0.01). Our results suggest that altered regulation of IL-8 in HIV-1 may have important implications for antimicrobial defenses and for normal immune processes.  (+info)

Infection of human endothelial cells with Chlamydia pneumoniae stimulates transendothelial migration of neutrophils and monocytes. (2/5836)

We have previously shown that different isolates of Chlamydia pneumoniae display heterogeneity in the in vitro stimulation of chemokines and adhesion molecules from infected human endothelial cells. In the present study, we examined the ability of different isolates of C. pneumoniae to promote transendothelial migration of neutrophils and monocytes. Human umbilical vein endothelial cells (HUVEC) were infected with low (<15)-passage C. pneumoniae isolates A-03, PS-32, and BR-393 and high (>40)-passage isolates BAL-16, TW-183, and T-2634, and levels of neutrophil and monocyte transendothelial migration were determined following 24 h of infection. Compared to mock-infected controls, significant increases in neutrophil migration were observed in response to most C. pneumoniae isolates examined (P < 0.001). Levels of monocyte migration were significantly increased in response to TW-183 and T-2634 (P < 0.001). Serial passage (>40 times) of the three low-passage isolates in HEp-2 cell cultures prior to infection of HUVEC generally resulted in the promotion of higher levels of neutrophil and monocyte transendothelial migration. These findings were compatible with differences observed in the extent of interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) stimulation between low- and high-passage A-03, PS-32, and BR-393. As opposed to C. pneumoniae, infection with C. trachomatis L2 caused only a slight increase in neutrophil transendothelial migration, which correlated with the lack of measurable IL-8 levels by this species. However, significant levels of monocyte migration were induced in response to C. trachomatis L2 despite a lack of measurable MCP-1 stimulation. C. trachomatis serovars A and E also failed to induce IL-8 and MCP-1 production in HUVEC. Results from this study indicate that the passage history of C. pneumoniae may play a role in the divergence of stimulatory activities observed among isolates in human endothelial cells. In addition, the differences observed between this organism and C. trachomatis suggest that the upregulation of IL-8 and MCP-1 in endothelial cells may be unique to C. pneumoniae.  (+info)

Responses of human intestinal microvascular endothelial cells to Shiga toxins 1 and 2 and pathogenesis of hemorrhagic colitis. (3/5836)

Endothelial damage is characteristic of infection with Shiga toxin (Stx)-producing Escherichia coli (STEC). Because Stx-mediated endothelial cell damage at the site of infection may lead to the characteristic hemorrhagic colitis of STEC infection, we compared the effects of Stx1 and Stx2 on primary and transformed human intestinal microvascular endothelial cells (HIMEC) to those on macrovascular endothelial cells from human saphenous vein (HSVEC). Adhesion molecule, interleukin-8 (IL-8), and Stx receptor expression, the effects of cytokine activation and Stx toxins on these responses, and Stx1 and Stx2 binding kinetics and bioactivity were measured. Adhesion molecule and IL-8 expression increased in activated HIMEC, but these responses were blunted in the presence of toxin, especially in the presence of Stx1. In contrast to HSVEC, unstimulated HIMEC constitutively expressed Stx receptor at high levels, bound large amounts of toxin, were highly sensitive to toxin, and were not further sensitized by cytokines. Although the binding capacities of HIMEC for Stx1 and Stx2 were comparable, the binding affinity of Stx1 to HIMEC was 50-fold greater than that of Stx2. Nonetheless, Stx2 was more toxic to HIMEC than an equivalent amount of Stx1. The decreased binding affinity and increased toxicity for HIMEC of Stx2 compared to those of Stx1 may be relevant to the preponderance of Stx2-producing STEC involved in the pathogenesis of hemorrhagic colitis and its systemic complications. The differences between primary and transformed HIMEC in these responses were negligible. We conclude that transformed HIMEC lines could represent a simple physiologically relevant model to study the role of Stx in the pathogenesis of hemorrhagic colitis.  (+info)

Interleukin-8 controls bacterial transepithelial translocation at the cost of epithelial destruction in experimental shigellosis. (4/5836)

In shigellosis, the network of cellular interactions mediated by a balance of pro- and anti-inflammatory cytokines or chemokines is clearly tipped toward acute destructive inflammation of intestinal tissues by the bacterial invader. This work has addressed the role played by interleukin-8 (IL-8) in a rabbit model of intestinal invasion by Shigella flexneri. IL-8, which is largely produced by the epithelial cells themselves, appears to be a major mediator of the recruitment of polymorphonuclear leukocytes (PMNs) to the subepithelial area and transmigration of these cells through the epithelial lining. Neutralization of IL-8 function by monoclonal antibody WS-4 caused a decrease in the amount of PMNs streaming through the lamina propria and the epithelium, thus significantly attenuating the severity of epithelial lesions in areas of bacterial invasion. These findings are in agreement with our previous work (31). In contrast to the PMNs, the bacteria displayed increased transepithelial translocation, as well as overgrowth in the lamina propria and increased passage into the mesenteric blood. By mediating eradication of bacteria at their epithelial entry site, although at the cost of severe epithelial destruction, IL-8 therefore appears to be a key chemokine in the control of bacterial translocation.  (+info)

Structure of cag pathogenicity island in Japanese Helicobacter pylori isolates. (5/5836)

BACKGROUND: cag pathogenicity island (PAI) is reported to be a major virulence factor of Helicobacter pylori. AIM: To characterise cagA and the cag PAI in Japanese H pylori strains. METHODS: H pylori isolates from Japanese patients were evaluated for CagA by immunoblot, for cagA transcription by northern blot, and for cagA and 13 other cag PAI genes by Southern blot. cagA negative strains from Western countries were also studied. Induction of interleukin-8 secretion from gastric epithelial cells was also investigated. RESULTS: All Japanese strains retained cagA. Fifty nine of 63 (94%) strains had all the cag PAI genes. In the remaining four, cag PAI was partially deleted, lacking cagA transcripts and not producing CagA protein. Details of the PAI of these strains were checked; three lacked cagB to cagQ (cagI) and continuously cagS to cag13 (cagII), and the remaining one lacked cagB to cag8. Western cagA negative strains completely lacked cag PAI including cagA. Nucleotide sequence analysis in one strain in which the cag PAI was partially deleted showed that the partial deletion contained 25 kb of cag PAI and the cagA promoter. Interleukin-8 induction was lower with the cag PAI partial deletion strains than with the intact ones. All Japanese cag PAI deleted strains were derived from patients with non-ulcer dyspepsia, whereas 41 of 59 (70%) CagA-producing strains were from patients with peptic ulcers or gastric cancer (p<0.05). CONCLUSIONS: Most Japanese H pylori strains had the intact cag PAI. However, some lacked most of the cag PAI in spite of the presence of cagA. Thus the presence of the cagA gene is not an invariable marker of cag PAI related virulence in Japanese strains.  (+info)

Vascular endothelial growth factor (VEGF)-mediated angiogenesis is associated with enhanced endothelial cell survival and induction of Bcl-2 expression. (6/5836)

Vascular endothelial growth factor (VEGF) is an endothelial cell mitogen and permeability factor that is potently angiogenic in vivo. We report here studies that suggest that VEGF potentiates angiogenesis in vivo and prolongs the survival of human dermal microvascular endothelial cells (HDMECs) in vitro by inducing expression of the anti-apoptotic protein Bcl-2. Growth-factor-enriched and serum-deficient cultures of HDMECs grown on collagen type I gels with VEGF exhibited a 4-fold and a 1.6-fold reduction, respectively, in the proportion of apoptotic cells. Enhanced HDMEC survival was associated with a dose-dependent increase in Bcl-2 expression and a decrease in the expression of the processed forms of the cysteine protease caspase-3. Cultures of HDMECs transduced with and overexpressing Bcl-2 and deprived of growth factors showed enhanced protection from apoptosis and exhibited a twofold increase in cell number and a fourfold increase in the number of capillary-like sprouts. HDMECs overexpressing Bcl-2 when incorporated into polylactic acid sponges and implanted into SCID mice exhibited a sustained fivefold increase in the number of microvessels and a fourfold decrease in the number of apoptotic cells when examined 7 and 14 days later. These results suggest that the angiogenic activity attributed to VEGF may be due in part to its ability to enhance endothelial cell survival by inducing expression of Bcl-2.  (+info)

Interleukin-12 is synthesized by mesangial cells and stimulates platelet-activating factor synthesis, cytoskeletal reorganization, and cell shape change. (7/5836)

Preliminary studies indicate the involvement of interleukin (IL)-12 in experimental renal pathology. In the present study, we evaluated whether cultured glomerular mesangial cells are able to produce IL-12 and whether IL-12 may regulate some of their functions, including the cytoskeletal reorganization, the change in cell shape, and the production of platelet-activating factor (PAF). The results obtained indicate that pro-inflammatory stimuli, such as tumor necrosis factor-alpha and bacterial polysaccharides, induce the expression of IL-12 mRNA and the synthesis of the protein by cultured mesangial cells. Moreover, cultured mesangial cells were shown to bind IL-12 and to express the human low-affinity IL-12 beta1-chain receptor. When challenged with IL-12, mesangial cells produced PAF in a dose- and time-dependent manner and superoxide anions. No production of tumor necrosis factor-alpha and IL-8 was observed. Moreover, we demonstrate that IL-12 induced a delayed and sustained shape change of mesangial cells that reached its maximum between 90 and 120 minutes of incubation. The changes in cell shape occurred concomitantly with cytoskeletal rearrangements and may be consistent with cell contraction. As IL-12-dependent shape change of mesangial cells was concomitant with the synthesis of PAF, which is known to promote mesangial cell contraction, we investigated the role of PAF using two chemically different PAF receptor antagonists. Both antagonists inhibited almost completely the cell shape change induced by IL-12, whereas they were ineffective on angiotensin-II-induced cell shape change. In conclusion, our results suggest that mesangial cells can either produce IL-12 or be stimulated by this cytokine to synthesize PAF and to undergo shape changes compatible with cell contraction.  (+info)

Interleukin-8: A pathogenetic role in antineutrophil cytoplasmic autoantibody-associated glomerulonephritis. (8/5836)

BACKGROUND: In neutrophil trafficking, the role of interleukin-8 (IL-8) is location dependent. Tissue IL-8 directs transmigration, whereas intravascular IL-8 frustrates this process. The bystander damage of glomerular endothelium by antineutrophil cytoplasmic autoantibody (ANCA)-activated neutrophils is believed to be an early event in the pathogenesis of ANCA-associated glomerulonephritis. We have studied the role of IL-8 in this process. METHODS: Intraglomerular expression of IL-8 in patients with ANCA-associated glomerulonephritis was studied by in situ hybridization and immunohistochemistry and location of neutrophils by serial section immunohistochemistry. In vitro, we analyzed ANCA-stimulated neutrophil IL-8 production by enzyme-linked immunosorbent assay, and the IL-8 attributable effect of ANCA-stimulated neutrophil supernatant by chemotactic and transendothelial assays. RESULTS: There was intraglomerular expression of IL-8 at segmental, crescentic, and parietal epithelial sites. IL-8 protein expression colocalized to intraglomerular neutrophils; many localized within glomerular capillary loops, suggesting failed trafficking to tissue IL-8. ANCAs differentially stimulated time- and dose-dependent neutrophil IL-8 production, and ANCA-stimulated neutrophil supernatant demonstrated potent IL-8-dependent chemotactic activity and inhibited transendothelial migration of normal human neutrophils toward an IL-8 gradient. CONCLUSION: Despite heavy tissue expression of IL-8 in ANCA-associated GN, the production of IL-8 by ANCA-stimulated neutrophils within the intravascular compartment may frustrate neutrophil transmigration, encourage intravascular stasis, and contribute to bystander damage of glomerular endothelial cells.  (+info)

TY - JOUR. T1 - Neutrophil recruitment by intradermally injected neutrophil attractant/activation protein-1. AU - Leonard, Edward J.. AU - Yoshimura, Teizo. AU - Tanaka, Shuji. AU - Raffeld, Mark. PY - 1991/5. Y1 - 1991/5. N2 - Neutrophil attractant/activation protein-1 (NAP-1) is a recently described cytokine that attracts neutrophils, but not monocytes or eosinophils. This leukocyte specificity is not absolute, in that NAP-1 attracts basophils and small numbers of lymphocytes. Our purpose was to determine in vivo effects of NAP-1, and to compare them to the reported action of the complement attractant, C5a. Intradermal injection into normal human subjects of 40 μl of NAP-1, over a concentration range of 4 × 10-8 M to 10-6 M, caused no symptoms or signs such as wheal-and-flare, itching, induration, or tenderness. However, biopsies of injection sites showed perivascular neutrophil infiltration as early as 30 min, which increased at 1 and 3 h. The mean number of neutrophils per mm2 of dermis ...
In this study we focused on the cellular infiltration in the bronchial mucosa of patients with post-infective bronchiectasis compared with corresponding bronchial biopsy specimens from normal healthy control subjects. The striking finding was an intense cellular infiltrate (with increased CD45+ cell numbers) with mononuclear cells (CD4+ T lymphocytes and macrophages), a prominent neutrophilia, and increased expression of the potent neutrophil chemoattractant IL-8. In those patients with bronchiectasis treated with inhaled steroids the T cell infiltrate (CD4+ cells) was significantly lower than in untreated patients. These findings support a role for cell mediated immune mechanisms in the pathogenesis of ongoing airways damage in bronchiectasis and its possible modulation by topical corticosteroids.. Previous immunohistological studies of bronchiectasis3 4performed in an experimental rat model of bronchiectasis and on human subjects have identified a relative increase in CD8+ T lymphocytes in ...
Interactions between the enteric pathogen Salmonella typhimurium and the luminal surface of the intestine provoke an acute inflammatory response, mediated in part by epithelial cell secretion of the chemokine IL-8 and other proinflammatory molecules. This study investigated the mechanism by which this pathogen induces IL-8 secretion in physiologically polarized model intestinal epithelia. IL-8 secretion induced by both the prototypical proinflammatory cytokine TNF-α and S. typhimurium was NF-κB dependent. However, NF-κB activation and IL-8 secretion induced by S. typhimurium, but not by TNF-α, was preceded by and required an increase in intracellular [Ca2+]. Additionally, agonists that increased intracellular [Ca2+] by receptor-dependent (carbachol) or independent (thapsigargin, ionomycin) means also induced IL-8 secretion. Furthermore, the ability of S. typhimurium mutants to induce IκB-α degradation, NF-κB translocation, and IL-8 transcription and secretion correlated precisely with ...
IL-8 is a potent neutrophil chemoattractant that has been detected in high concentrations at acutely inflamed sites in vivo. Many cell types, including peripheral blood neutrophils, produce IL-8 that can be released by a variety of pro-inflammatory stimuli. However, the functional importance of neutrophil IL-8 during exudation is not yet known. We now report that neutrophils, harvested from skin lesions on the forearms of normal human volunteers (exudative neutrophils), expressed 100-fold higher levels of cell-associated IL-8 and spontaneously released up to 50-fold more IL-8 than freshly isolated peripheral blood neutrophils from the same donor. Furthermore, cell-associated IL-8 in peripheral blood neutrophils increased 20-fold during incubation at 37 degrees C in vitro and was increased over 200-fold after treatment with the Ca2+ ionophore A23187. More than 35% of the cell-associated IL-8 could be released by stimulation with either Ca2+ ionophore A23187 or phorbol myristate acetate. IL-8 was ...

Primary human lung cells or cell lines were cultured on a stretchable silastic membrane forming the bottom of a 12-well plexiglas® box. The box was connected to an adult ventilator and ventilated for up to 36 hours at 20 cycles/min with a pressure-volume regimen resembling that of MV. Several lung cell types were tested in this model. The alveolar macrophage was identified as the main cellular source of key inflammatory mediators, such as tumor necrosis factor, the chemokine interleukin (IL)-8, and matrix metalloproteinase-9, produced during mechanical ventilation. Mechanical ventilation also induced low levels of IL-8 secretion by human alveolar epithelial type II-like cells. Other lung cell types such as endothelial cells, bronchial cells, and fibroblasts failed to produce IL-8 in response to mechanical ventilation (1,2). Conclusions and Relevance for 3R ...
Using thapsigargin (Tg), an agent that mobilizes calcium by directly emptying intracellular stores, we previously showed that intracellular calcium may play an important role in the regulation of intercellular adhesion molecule (ICAM)-1 gene expression induced by cytokines in human airway smooth muscle (ASM) cells. In the present study, we extended this previous observation by comparing the effect of Tg and other calcium-mobilizing G-protein-coupled receptor (GPCR) agonists on the expression of different pro-inflammatory genes in response to tumor necrosis factor (TNF)-alpha in ASM cells. We found that in resting cells, Tg (10-100 nM) or the bradykinin (BK) (1-10 muM) and thrombin (Thr) (1 U/ml) stimulated interleukin (IL)-6 secretion but had no effect on regulated on activation, normal T cells expressed and secreted (RANTES) levels. More importantly, such calcium-mobilizing agents significantly enhanced TNF-alpha-induced IL-6 secretion while RANTES secretion was abrogated. The use of ...

N2 - Human monocyte-derived neutrophil chemotactic factor (MDNCF) was purified from culture supernatant of lipopolysaccharide-stimulated human peripheral blood mononuclear leukocytes on a column of Sepharose-bound murine monoclonal anti-MDNCF. About 65% of the culture fluid chemotactic activity was bound to the column. The unbound 35% probably represents chemotactic activity of other cytokines in the culture fluid. More than 85% of the bound activity was eluted by pH 2.5 glycine buffer. When this material was applied to an HPLC-CM column, gradient elution produced four well-separated A280 peaks, each of which had chemotactic activity. N-terminal amino ...
Chemokine (C-C motif) ligand 5 (also CCL5) is a protein which in humans is encoded by the CCL5 gene. It is also known as RANTES (regulated on activation, normal T cell expressed and secreted). CCL5 is an 8kDa protein classified as a chemotactic cytokine or chemokine. CCL5 is chemotactic for T cells, eosinophils, and basophils, and plays an active role in recruiting leukocytes into inflammatory sites. With the help of particular cytokines (i.e., IL-2 and IFN-γ) that are released by T cells, CCL5 also induces the proliferation and activation of certain natural-killer (NK) cells to form CHAK (CC-Chemokine-activated killer) cells. It is also an HIV-suppressive factor released from CD8+ T cells[citation needed]. This chemokine has been localized to chromosome 17 in humans. RANTES was first identified in a search for genes expressed late (3-5 days) after T cell activation. It was subsequently determined to be a CC chemokine and expressed in more than 100 human diseases. RANTES expression is ...

Results In C57BL/6 mice, gefitinib decreased Cxcl1 and Cxcl2 expression by gastric epithelial cells, myeloperoxidase-positive inflammatory cells in the mucosa and epithelial DNA damage induced by H. pylori infection. Similar reductions in chemokines, inflammatory cells and DNA damage occurred in infected EgfrΔepi versus Egfrfl/fl control mice. In H. pylori-infected transgenic insulin-gastrin (INS-GAS) mice and gerbils, gefitinib treatment markedly reduced dysplasia and carcinoma. Gefitinib blocked H. pylori-induced activation of mitogen-activated protein kinase 1/3 (MAPK1/3) and activator protein 1 in gastric epithelial cells, resulting in inhibition of chemokine synthesis. MAPK1/3 phosphorylation and JUN activation was reduced in gastric tissues from infected wild-type and INS-GAS mice treated with gefitinib and in primary epithelial cells from EfgrΔepi versus Egfrfl/fl mice. Epithelial EGFR activation persisted in humans and mice after H. pylori eradication, and gefitinib reduced gastric ...
These studies demonstrate that GM-CSF is a neutrophil chemotactic agent. The concentration of GM-CSF needed to achieve maximal chemotaxis is comparable to that of the potent neutrophil chemoattractant IL-8 and less than the other known chemoattractants that we studied. We believe that GM-CSF induction of neutrophil chemotaxis has been previously unrecognized because the stimulatory effect occurs in a narrow range of concentrations (Fig. 3⇑A) and requires an extended incubation interval of at least 30 min. Results reported by Harakawa et al. (44) agreed with our finding that GM-CSF produces an early stimulation of neutrophil chemokinesis, but observations were not reported past 15 min, which may have been insufficient to recognize an effect on chemotaxis. Other earlier studies provided contradictory data on the effect of GM-CSF on neutrophil migration. In a checkerboard assay using polycarbonate filters, Wang et al. (45) demonstrated that GM-CSF induced chemotaxis in neutrophils, while Kharazmi ...
Chemokines are a large group of chemotactic cytokines that play an important pathogenic role in inflammatory diseases and autoimmune disorders by enhancement of leukocyte recruitment and activation at inflammatory sites [3-6]. ENA-78 is a CXC chemokine that attracts neutrophils during inflammation [7].. In this work, serum levels of ENA-78 were significantly higher in autistic children than healthy control children (P , 0.001). In addition, 69.35% of autistic children had increased serum levels of ENA-78. This study was the first to investigate serum levels of ENA-78 in autistic children. ENA-78 is an inflammatory C-X-C chemokine that is encoded by the CXCL5 gene [28]. Its levels are elevated in myriad inflammatory conditions [29-32].. ENA-78 is an α chemokine which is produced concomitantly with IL-8 and melanoma growth stimulating activity [7]. The main stimuli for secretion of chemokines, including ENA-78, are the early signals elicited during innate immune response such as bacterial ...
A potential new strategy to developing new drugs to control inflammation without serious side effects has been found by Georgia State University researchers and international colleagues.. Jian-Dong Li, director of Georgia States Center for Inflammation, Immunity and Infection, and his team discovered that blocking a certain pathway involved in the biological process of inflammation will suppress it.. Inhibiting a molecule called phosphodiesterase 4B, or PDE4B, suppresses inflammation by affecting a key gene called CLYD, a gene that serves as a brake on inflammation.. The research was published in the journal Nature Communications.. Li explained the process of overactive inflammation using a police analogy.. When a pathogen - such as bacteria or viruses -- infects a patient, he said, it triggers an alarm to which the police of immune system respond. In turn, it triggers neutrophil attractant called cytokines to respond, leading to inflammation that serves to help rid the body of the ...
CCL5 is an 8kDa protein classified as a chemotactic cytokine or chemokine. CCL5 is chemotactic for T cells, eosinophils, and basophils, and plays an active role in recruiting leukocytes into inflammatory sites. With the help of particular cytokines (i.e., IL-2 and IFN-γ) that are released by T cells, CCL5 also induces the proliferation and activation of certain natural-killer (NK) cells to form CHAK (CC-Chemokine-activated killer) cells.[6] It is also an HIV-suppressive factor released from CD8+ T cells[citation needed]. This chemokine has been localized to chromosome 17 in humans.[5]. RANTES was first identified in a search for genes expressed late (3-5 days) after T cell activation. It was subsequently determined to be a CC chemokine and expressed in more than 100 human diseases. RANTES expression is regulated in T lymphocytes by Kruppel like factor 13 (KLF13).[7][8][9][10] RANTES, along with the related chemokines MIP-1alpha and MIP-1beta, has been identified as a natural HIV-suppressive ...
Human IL-16 (hIL-16) is a homotetrameric cytokine with chemotactic properties towards cells expressing the CD4 receptor. This chemotactic cytokine plays an important role in attracting cells of the immune system to the site where CD8+ T-cells were activated for example by a foreign antigen. In addition to the chemotactic activity, hIL-16 also induces expression of IL-2 receptor, increasing the responsiveness to IL-2 and therefore implying a role for specific expansion of the CD4+ T-cell population in an area of induced inflammation. In this report we describe the cloning, sequencing and the expression of feline IL-16 (fIL-16). At the nucleotide level, fIL-16 shows 84.6 and 84.5%, on the amino acid level 93 and 91.5% identity to the human and African green monkey (agm) IL-16, respectively. ...
Methods Quiescent cultured RASMCs were pretreated with E2 or vehicle for 24 hours before tumor necrosis factor (TNF)-α was added. After 6 hours of treatment, total RNA was extracted from cells using TRIzol reagent, and SYBR green real-time RT-PCR was used to detect expression of CINC-2 mRNA. Conditioned media was collected and concentrated to measure CINC-2 protein level by ELISA. To assess neutrophil chemotactic activity of conditioned media, in vitro chemotaxis assays were performed using differentiated HL-60 cells in a 96-well modified Boyden chamber appropriate for the evaluation of leukocyte chemotaxis. The nonselective ER antagonist ICI-182780 was given to cells 2 hours prior to E2 incubation to study the mechanism of E2 effect. ...

Abstract: : Purpose: Adenovirus infection of the cornea manifests as punctate epithelial keratitis, geographic epithelial erosions, and delayed-onset subepithelial corneal infiltrates. We have previously shown that (1)adenovirus type 19 (Ad19) infection of human corneal fibroblasts (HCF) induces expression of the neutrophil chemokine interleukin-8 (IL-8); (2) Ad19 infection of HCF induces tyrosine phosphorylation of the intracellular signaling protein c-src; and (3) phosphorylation of c-src is necessary for the expression of IL-8 by Ad19-infected HCF. These data suggest that Ad19 induces IL-8 expression in HCF by a signaling cascade involving c-src. In the experiments described herein, we sought to determine whether adenovirus infection of HCF might induce other host responses dependent on c-src associated signaling pathways. Methods: HCF were derived from donor corneas and infected for one hour with Ad19, or mock-infected with virus-free media. Parallel experiments were performed with the ...
Schizophrenia patients typically exhibit cognitive impairments that directly affect their daily functioning, but are not effectively treated by current antipsychotics. Maternal immune activation (MIA) during pregnancy, which can be triggered by a variety of infectious agents, has been associated with the development of schizophrenia in adult offspring. Epidemiological evidence indicates that elevated maternal levels of the chemokine interleukin- 8 (IL-8) during MIA contribute to the neurodevelopmental alterations underlying the disorder. The present experiments used an animal model of neurodevelopmental disorders to study the effects of MIA and chemokine receptor antagonism on the behavior of rat offspring, with behavioral tests chosen to examine cognitive functions that are typically impaired in human schizophrenia patients. The viral mimetic polyinosinic-polycytidylic acid (polyI:C) (4.0 mg/kg, i.v.) was injected into pregnant Long-Evans (LE) dams on gestational day (GD) 15. Dams were also ...
TY - JOUR. T1 - Increased expression of epidermal interleukin-8 receptor in psoriasis. Downregulation by FK-506. AU - Schulz, B. S.. AU - Michel, G.. AU - Wagner, S.. AU - Suss, R.. AU - Angerpoitner, T.. AU - Kemeny, L.. AU - Ruzicka, T.. PY - 1994/12/1. Y1 - 1994/12/1. N2 - IL-8 is a chemotactic cytokine with proinflammatory and growth promoting activities. Recently it has been shown to influence several functions of keratinocytes, including HLA-DR expression, chemotaxis and proliferation by binding to a specific receptor. Since psoriasis vulgaris is characterized by epidermal hyperproliferation and infiltration of inflammatory cells, we investigated the expression of IL-8 and its receptor in normal and psoriatic epidermis using semiquantitative reverse-transcriptase-PCR. In addition the mRNA levels of the protooncogenes c-ras, c-raf, c-myc and HER-2 were also investigated as potential growth promoting stimuli in psoriatic epidermis. IL-8 mRNA was only detected in lesional psoriatic epidermis, ...

Description: Description of target: C-X-C motif chemokine 5 is a protein that in humans encoded by the CXCL5 gene. The protein encoded by this gene, CXCL5 is a small cytokine belonging to the CXC chemokine family that is also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78). It is produced following stimulation of cells with the inflammatory cytokines interleukin-1or tumor necrosis factor-alpha. Expression of CXCL5 has also been observed in eosinophils, and can be inhibited with the type II interferon IFN-gamma. This chemokine stimulates the chemotaxis of neutrophils possessing angiogenic properties. It elicits these effects by interacting with the cell surface chemokine receptor CXCR2. The gene for CXCL5 is encoded on four exons and is located on humanchromosome 4 amongst several other CXC chemokine genes. CXCL5 has been implicated in connective tissue remodeling. CXCL5 plays a role in reducing sensitivity to sunburn pain in some subjects, and is a potential target which ...
The presence of neutrophils in the synovial joint of patients with rheumatoid arthritis (RA) is thought to be due to the activity of chemotactic factors released by activated cells in the joint. We have shown in this report, for the first time, the abundance of one such factor, interleukin 8 (IL 8), in the synovial fluid of patients both with RA and other non-RA joint diseases, and the spontaneous production of IL 8 mRNA by RA synovial cells in culture. There was no correlation between the levels of chemotactic activity and IL 8 protein, suggesting that other factors with similar neutrophil chemotactic activity are also present in the synovial fluid exudate. In support of this concept neither the level of chemotactic activity nor IL 8 protein levels correlated with neutrophil or leukocyte infiltration, indicating that the mechanism of migration into the inflammatory environment of the joint is complex. Such migration is likely to be due to a number of chemotactic signals in addition to IL 8, which may
Chemokine (C-X-C motif) ligand 1 (CXCL1) is a small cytokine belonging to the CXC chemokine family that was previously called GRO1 oncogene, GROα, KC, Neutrophil-activating protein 3 (NAP-3) and melanoma growth stimulating activity, alpha (MSGA-α). In humans, this protein is encoded by the CXCL1 gene.

In this series of experiments we have demonstrated that the stimulated release of IL-6 and IL-8 from cultures obtained from controls and smokers without airflow obstruction is amplified by 5% CSE pretreatment, but this was not apparent in the COPD group. Our results also show cellular immunosuppressive effects of 5% CSE in the COPD cultures. These findings suggest that COPD PBECs are more susceptible to the immunosuppressive effects of CSE which may explain, in part, the increased susceptibility of this particular group to respiratory infections.. In our experiments, 5% CSE reduced the expression of TLR-4. Similar findings were recently reported using a human bronchial epithelial cell line, where CSE treatment led to a downregulation of TLR-4 expression, which was associated with a corresponding increase in the release of IL-8. Internalisation of the receptor was proposed as the mechanism, as there was a parallel increase in the expression of TLR-4 in permeabilised cells [4]. However, the ...
