Macrophage inflammatory protein-2 is required for neutrophil passage across the epithelial barrier of the infected urinary tract. (1/731)

IL-8 is a major human neutrophil chemoattractant at mucosal infection sites. This study examined the C-X-C chemokine response to mucosal infection, and, specifically, the role of macrophage inflammatory protein (MIP)-2, one of the mouse IL-8 equivalents, for neutrophil-epithelial interactions. Following intravesical Escherichia coli infection, several C-X-C chemokines were secreted into the urine, but only MIP-2 concentrations correlated to neutrophil numbers. Tissue quantitation demonstrated that kidney MIP-2 production was triggered by infection, and immunohistochemistry identified the kidney epithelium as a main source of MIP-2. Treatment with anti-MIP-2 Ab reduced the urine neutrophil numbers, but the mice had normal tissue neutrophil levels. By immunohistochemistry, the neutrophils were found in aggregates under the pelvic epithelium, but in control mice the neutrophils crossed the urothelium into the urine. The results demonstrate that different chemokines direct neutrophil migration from the bloodstream to the lamina propria and across the epithelium and that MIP-2 serves the latter function. These findings suggest that neutrophils cross epithelial cell barriers in a highly regulated manner in response to chemokines elaborated at this site. This is yet another mechanism that defines the mucosal compartment and differentiates the local from the systemic host response.  (+info)

A functional granulocyte colony-stimulating factor receptor is required for normal chemoattractant-induced neutrophil activation. (2/731)

Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic growth factor that is widely used to treat neutropenia. In addition to stimulating polymorphonuclear neutrophil (PMN) production, G-CSF may have significant effects on PMN function. Because G-CSF receptor (G-CSFR)-deficient mice do not have the expected neutrophilia after administration of human interleukin-8 (IL-8), we examined the effect of the loss of G-CSFR on IL-8-stimulated PMN function. Compared with wild-type PMNs, PMNs isolated from G-CSFR-deficient mice demonstrated markedly decreased chemotaxis to IL-8. PMN emigration into the skin of G-CSFR-deficient mice in response to IL-8 was also impaired. Significant chemotaxis defects were also seen in response to N-formyl-methionyl-leucyl-phenylalanine, zymosan-activated serum, or macrophage inflammatory protein-2. The defective chemotactic response to IL-8 does not appear to be due to impaired chemoattractant receptor function, as the number of IL-8 receptors and chemoattractant-induced calcium influx, actin polymerization, and release of gelatinase B were comparable to those of wild-type PMNs. Chemoattractant-induced adhesion of G-CSFR-deficient PMNs was significantly impaired, suggesting a defect in beta2-integrin activation. Collectively, these data demonstrate that selective defects in PMN activation are present in G-CSFR-deficient mice and indicate that G-CSF plays an important role in regulating PMN chemokine responsiveness.  (+info)

Regulation of early peritoneal neutrophil migration by macrophage inflammatory protein-2 and mast cells in experimental peritonitis. (3/731)

Neutrophil (PMN) migration into the peritoneal cavity in response to fecal peritonitis is an important mechanism of host defense against bacterial invasion. We show that the murine C-X-C (PMN-specific) chemokine, macrophage inflammatory protein-2 (MIP-2), on intraperitoneal injection in mice, causes PMN migration into the peritoneum. MIP-2 mRNA and protein were expressed by peritoneal leukocytes after cecal ligation and puncture (CLP) in mice and neutralization of MIP-2 reduced peritoneal PMN migration. A prerequisite for neutrophil-endothelial adhesion and subsequent migration from the circulation is selectin-mediated rolling. Pretreatment of mice with an anti-P-selectin antibody before intraperitoneal injection of MIP-2 significantly reduced peritoneal PMN migration. However, there are no reports that a C-X-C chemokine can up-regulate endothelial selectins. We postulated that MIP-2, when injected intraperitoneally, interacts with a cell that is known to release factors that up-regulate endothelial selectins. A likely candidate is the mast cell, which contains histamine and tumor necrosis factor alpha (TNF-alpha), and both of these factors induce selectins. Intraperitoneally injected MIP-2 caused an early significant increase in peritoneal TNF-alpha, whereas histamine levels were unaffected. In a subsequent experiment, mast cell-deficient mice and their normal controls were then injected intraperitoneally with MIP-2 or underwent CLP. Significantly fewer PMNs migrated into the peritoneal cavity in the mast cell-deficient mice after MIP-2 injection or CLP. Thus, our findings indicate that mast cells and MIP-2 are necessary for PMN migration into the peritoneum in response to intra-abdominal infection, and that MIP-2 appears to facilitate this through an increase in TNF-alpha release.  (+info)

Intracellular oxidant production and cytokine responses in lung macrophages: evaluation of fluorescent probes. (4/731)

The fluorescent probes dichlorofluorescin (DCFH), dihydrorhodamine (DHR), and hydroethidine (HE) allow convenient assay of alveolar macrophage (AM) oxidant responses to enviromental particulates and pathogens. We sought to more precisely define the relationship of these measures of oxidant stress to production of pro-inflammatory cytokines. Normal AMs were challenged in vitro with a panel of soluble or particulate stimuli in the presence of DCFH, HE, or DHR. Flow cytometry measured cell-associated fluorescence and relative particle uptake. Tumor necrosis factor alpha and macrophage inflammatory protein 2 expression were quantitated in the same experiments. We observed variable and complex correlations between intracellular oxidant production as reported by these probes and subsequent cytokine response, including examples of striking discordance (e.g., lipopolysaccharide induced large cytokine responses with minimal probe oxidation, whereas fly ash particles caused marked oxidation of DCFH but trivial TNF release; TiO2 caused oxidation of DHR and HE, but not DCFH, and also did not increase cytokine production). Although fluorescent probes offer many advantages in analysis of intracellular oxidant responses, the data indicate that they cannot be used reliably as quantitative predictors of AM cytokine responses to environmental particulates or other stimuli.  (+info)

Upregulation of the chemokines Rantes, MCP-1, MIP-1a and MIP-2 in early infection with Trypanosoma brucei brucei and inhibition by sympathetic denervation of the spleen. (5/731)

We examined the induction of 4 chemokines during early experimental African trypanosomiasis using in situ hybridization and immunocytochemistry. mRNA expression and protein production of Rantes, MCP-1, MIP-1a and MIP-2 were studied in splenocytes obtained at 0 h, 4 h and 12 h post-infection. Splenic denervation was performed to study the role of the central nervous system in early infection. The mRNA for Rantes increased at 4 h and declined at 12 h, but the protein level was high at both time-points. MCP-1 and MIP-la had elevated mRNA and protein levels at 12 h post-infection. MIP-2 mRNA was high at both 4 h and 12 h, but the protein level was only increased at 12 h. Splenic denervation, but not sham operation, suppressed these responses. The upregulation of these chemokines during very early infection suggests a chemokine role in the developing immunopathology The sympathetic nervous system may, however, participate in modulation of such early immune responses.  (+info)

Neutralization of macrophage inflammatory protein 2 (MIP-2) and MIP-1alpha attenuates neutrophil recruitment in the central nervous system during experimental bacterial meningitis. (6/731)

Chemokines are low-molecular-weight chemotactic cytokines that have been shown to play a central role in the perivascular transmigration and accumulation of specific subsets of leukocytes at sites of tissue damage. Using in situ hybridization (ISH), we investigated the mRNA induction of macrophage inflammatory protein 2 (MIP-2), MIP-1alpha, monocyte chemoattractant protein 1 (MCP-1), and RANTES. Challenge of infant rats' brains with Haemophilus influenzae type b intraperitoneally resulted in the time-dependent expression of MIP-2, MIP-1alpha, MCP-1, and RANTES, which was maximal 24 to 48 h postinoculation. Immunohistochemistry showed significant increases in neutrophils and macrophages infiltrating the meninges, the ventricular system, and the periventricular area. The kinetics of MIP-2, MIP-1alpha, MCP-1, and RANTES mRNA expression paralleled those of the recruitment of inflammatory cells and disease severity. Administration of anti-MIP-2 or anti-MIP-1alpha antibodies (Abs) resulted in significant reduction of neutrophils. Administration of anti-MCP-1 Abs significantly decreased macrophage infiltration. Combined studies of ISH and immunohistochemistry showed that MIP-2- and MIP-1alpha-positive cells were neutrophils and macrophages. MCP-1-positive cells were neutrophils, macrophages, and astrocytes. Expression of RANTES was localized predominantly to resident astrocytes and microglia. The present study indicates that blocking of MIP-2 or MIP-1alpha bioactivity in vivo results in decreased neutrophil influx. These data are also the first demonstration that the C-C chemokine MIP-1alpha is involved in neutrophil recruitment in vivo.  (+info)

Neutralization of the CXC chemokine, macrophage inflammatory protein-2, attenuates bleomycin-induced pulmonary fibrosis. (7/731)

Few studies have addressed the importance of vascular remodeling in the lung during the development of bleomycin-induced pulmonary fibrosis. For fibroplasia and deposition of extracellular matrix to occur, there must be a geometric increase in neovascularization. We hypothesized that net angiogenesis during the pathogenesis of fibroplasia and deposition of extracellular matrix during bleomycin-induced pulmonary fibrosis are dependent in part upon an overexpression of the angiogenic CXC chemokine, macrophage inflammatory protein-2 (MIP-2). To test this hypothesis, we measured MIP-2 by specific ELISA in whole lung homogenates in either bleomycin-treated or control CBA/J mice and correlated these levels with lung hydroxyproline. We found that lung tissue from mice treated with bleomycin, compared with that from saline-treated controls, demonstrated a significant increase in the presence of MIP-2 that was correlated to a greater angiogenic response and total lung hydroxyproline content. Neutralizing anti-MIP-2 Abs inhibited the angiogenic activity of day 16 bleomycin-treated lung specimens using an in vivo angiogenesis bioassay. Furthermore, when MIP-2 was depleted in vivo by passive immunization, bleomycin-induced pulmonary fibrosis was significantly reduced without a change in the presence of pulmonary neutrophils, fibroblast proliferation, or collagen gene expression. This was also paralleled by a reduction in angiogenesis. These results demonstrate that the angiogenic CXC chemokine, MIP-2, is an important factor that regulates angiogenesis/fibrosis in pulmonary fibrosis.  (+info)

Granulocyte colony-stimulating factor modulates the pulmonary host response to endotoxin in the absence and presence of acute ethanol intoxication. (8/731)

Alcohol impairs neutrophil function and predisposes the host to infectious complications. Granulocyte colony-stimulating factor (G-CSF) increases both the number and functional activities of neutrophils. This study investigated the effects of G-CSF on the pulmonary response to endotoxin in rats with or without acute ethanol intoxication. Acute ethanol intoxication inhibited tumor necrosis factor (TNF)-alpha and macrophage inflammatory protein (MIP)-2 production in the lung and suppressed the recruitment of neutrophils into the lung. Ethanol also inhibited CD11b/c expression on recruited neutrophils and suppressed the phagocytic activity of circulating neutrophils. G-CSF pretreatment up-regulated CD11b/c expression on circulating polymorphonuclear leukocytes, augmented the recruitment of neutrophils into the lung, and enhanced the phagocytic activity of circulating and recruited neutrophils in both the absence and presence of acute ethanol intoxication. G-CSF inhibited MIP-2 but not TNF-alpha production in the lung. These data suggest that G-CSF may be useful in the prevention or treatment of infections in persons immunocompromised by alcohol.  (+info)

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

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 ...
A cytotoxic cycle triggered by DNA single-strand breakage and poly (ADP-ribose) synthetase activation has been shown to contribute to the cellular injury during various forms of oxidant stress in vitro. The aim of this study was to investigate the role of poly (ADP-ribose) synthetase (PARS) in the process of neutrophil recruitment and in development of local and systemic inflammation. In pharmacological studies, PARS was inhibited by 3-aminobenzamide (10-20 mg/kg) in rats and mice. In other sets of studies, inflammatory responses in PARS?/? mice were compared with the responses in corresponding wild-type controls. Inhibition of PARS reduced neutrophil recruitment and reduced the extent of edema in zymosan- and carrageenan-triggered models of local inflammation. Moreover, inhibition of PARS prevented neutrophil recruitment, and reduced organ injury in rodent models of inflammation and multiple organ failure elicited by intraperitoneal injection of zymosan. Inhibition of PARS also reduced the ...
GRO (Growth Related Oncogene) belonging to IL-8 family is polypeptide which has three isoforms α, β and γ, and it inhibits proliferation of endothelial cells. GRO/CINC-1 (cytokine-induced neutrophil chemo attractant 1) was originally purified from media conditioned by IL-1β stimulated rat kidney epithelioid cells (NRK-52E.) Amino acid sequence that encodes rat CINC-1 was identified in 1989 by Watanabes group at Toyama Medical and Pharmaceutical University. CINC-1 is a member of the alpha (CXC) subfamily of chemokines. Three additional rat CXC chemokines (CINC-2α, CINC-2β, CINC-3/MIP-2) have been identified. The protein sequence of CINC-1 is 63 - 67% identical to that of CINC-2α, CINC-2β and CINC-3/MIP-2. In addition, each of GROα, GROβ and GROγ is sharing 68%, 71% and 69% identity with CINC-1. This has been suggested that CINCs are the rat counterparts of human GROs. GROα/MGSA has a high homology with IL-8 in amino acid sequences. It has been reported that it also has a similar ...

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 ...

... s are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte.[1] They are protein mediators typically produced by T cells to direct the immune system response by signaling between its cells. Lymphokines have many roles, including the attraction of other immune cells, including macrophages and other lymphocytes, to an infected site and their subsequent activation to prepare them to mount an immune response. Circulating lymphocytes can detect a very small concentration of lymphokine and then move up the concentration gradient towards where the immune response is required. Lymphokines aid B cells to produce antibodies. Important lymphokines secreted by the T helper cell include:[2] ...
... binds to the death receptors DR4 (TRAIL-RI) and DR5 (TRAIL-RII). The process of apoptosis is caspase-8-dependent. Caspase-8 activates downstream effector caspases including procaspase-3, -6, and -7, leading to activation of specific kinases.[11] TRAIL also binds the receptors DcR1 and DcR2, which do not contain a cytoplasmic domain (DcR1) or contain a truncated death domain (DcR2). DcR1 functions as a TRAIL-neutralizing decoy-receptor. The cytoplasmic domain of DcR2 is functional and activates NFkappaB. In cells expressing DcR2, TRAIL binding therefore activates NFkappaB, leading to transcription of genes known to antagonize the death signaling pathway and/or to promote inflammation. Application of engineered ligands that have variable affinity for different death (DR4 and DR5) and decoy receptors (DCR1 and DCR2) may allow selective targeting of cancer cells by controlling activation of Type 1/Type 2 pathways of cell death and single cell fluctuations. Luminescent iridium complex-peptide ...
... (IL-24) is a protein that in humans is encoded by the IL24 gene. IL-24 is a cytokine belonging to the IL-10 family of cytokines that signals through two heterodimeric receptors: IL-20R1/IL-20R2 and IL-22R1/IL-20R2. This interleukin is also known as melanoma differentiation-associated 7 (mda-7) due to its discovery as a tumour suppressing protein. IL-24 appears to control in cell survival and proliferation by inducing rapid activation of particular transcription factors called STAT1 and STAT3. This cytokine is predominantly released by activated monocytes, macrophages and T helper 2 (Th2) cells[5] and acts on non-haematopoietic tissues such as skin, lung and reproductive tissues. IL-24 performs important roles in wound healing, arthritis, psoriasis and cancer.[6][7][8] Several studies have shown that cell death occurs in cancer cells/cell lines following exposure to IL-24.[9][10] The gene for IL-24 is located on chromosome 1 in humans.[11] ...

... is sometimes used interchangeably among scientists with the term cytokine.[3] Historically, cytokines were associated with hematopoietic (blood and lymph forming) cells and immune system cells (e.g., lymphocytes and tissue cells from spleen, thymus, and lymph nodes). For the circulatory system and bone marrow in which cells can occur in a liquid suspension and not bound up in solid tissue, it makes sense for them to communicate by soluble, circulating protein molecules. However, as different lines of research converged, it became clear that some of the same signaling proteins which the hematopoietic and immune systems use were also being used by all sorts of other cells and tissues, during development and in the mature organism. While growth factor implies a positive effect on cell division, cytokine is a neutral term with respect to whether a molecule affects proliferation. While some cytokines can be growth factors, such as G-CSF and GM-CSF, others have an inhibitory effect on ...
