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.

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)

For example, some drugs can block the activity of enzymes that are involved in cell migration, while others can interfere with the signaling pathways that regulate cell movement. In cancer research, cell migration inhibition is often used as a strategy to prevent the spread of cancer cells to other parts of the body, a process known as metastasis. By blocking cell migration, researchers hope to develop new treatments that can slow down or stop the progression of cancer. Overall, cell migration inhibition is an important concept in the medical field, as it can provide insights into the underlying mechanisms of various diseases and help to identify new therapeutic targets for treatment.

Intercellular signaling peptides and proteins are molecules that are secreted by cells and act as messengers to communicate with other cells. These molecules can be hormones, growth factors, cytokines, or other signaling molecules that are capable of transmitting information between cells. They play a crucial role in regulating various physiological processes, such as cell growth, differentiation, and apoptosis, as well as immune responses and inflammation. In the medical field, understanding the function and regulation of intercellular signaling peptides and proteins is important for developing new treatments for various diseases and disorders, including cancer, autoimmune diseases, and neurological disorders.

Tumor Necrosis Factor-alpha (TNF-alpha) is a cytokine, a type of signaling protein, that plays a crucial role in the immune response and inflammation. It is produced by various cells in the body, including macrophages, monocytes, and T cells, in response to infection, injury, or other stimuli. TNF-alpha has multiple functions in the body, including regulating the immune response, promoting cell growth and differentiation, and mediating inflammation. It can also induce programmed cell death, or apoptosis, in some cells, which can be beneficial in fighting cancer. However, excessive or prolonged TNF-alpha production can lead to chronic inflammation and tissue damage, which can contribute to the development of various diseases, including autoimmune disorders, inflammatory bowel disease, and certain types of cancer. In the medical field, TNF-alpha is often targeted in the treatment of these conditions. For example, drugs called TNF inhibitors, such as infliximab and adalimumab, are used to block the action of TNF-alpha and reduce inflammation in patients with rheumatoid arthritis, Crohn's disease, and other inflammatory conditions.

NF-kappa B (Nuclear Factor kappa B) is a transcription factor that plays a critical role in regulating the immune response, inflammation, and cell survival. It is a complex of proteins that is found in the cytoplasm of cells and is activated in response to various stimuli, such as cytokines, bacterial and viral infections, and stress. When activated, NF-kappa B translocates to the nucleus and binds to specific DNA sequences, promoting the expression of genes involved in immune and inflammatory responses. This includes genes encoding for cytokines, chemokines, and adhesion molecules, which help to recruit immune cells to the site of infection or injury. NF-kappa B is also involved in regulating cell survival and apoptosis (programmed cell death). Dysregulation of NF-kappa B signaling has been implicated in a variety of diseases, including cancer, autoimmune disorders, and inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease.

Chemotactic factors, eosinophil are chemical substances that attract eosinophils, a type of white blood cell, to a specific location in the body. These factors are produced by various cells, including immune cells and cells in the lining of tissues, in response to inflammation or infection. Eosinophils play a role in the immune response to parasitic infections and allergies, and they are also involved in tissue repair and remodeling. Chemotactic factors for eosinophils can be either proteinaceous or lipid-based, and they bind to specific receptors on the surface of eosinophils, guiding them to the site of inflammation or infection.

Lipopolysaccharides (LPS) are a type of complex carbohydrate found on the surface of gram-negative bacteria. They are composed of a lipid A moiety, a core polysaccharide, and an O-specific polysaccharide. LPS are important components of the bacterial cell wall and play a role in the innate immune response of the host. In the medical field, LPS are often studied in the context of sepsis, a life-threatening condition that occurs when the body's response to an infection causes widespread inflammation. LPS can trigger a strong immune response in the host, leading to the release of pro-inflammatory cytokines and other mediators that can cause tissue damage and organ failure. As a result, LPS are often used as a model for studying the pathophysiology of sepsis and for developing new treatments for this condition. LPS are also used in research as a tool for studying the immune system and for developing vaccines against bacterial infections. They can be purified from bacterial cultures and used to stimulate immune cells in vitro or in animal models, allowing researchers to study the mechanisms of immune responses to bacterial pathogens. Additionally, LPS can be used as an adjuvant in vaccines to enhance the immune response to the vaccine antigen.

In the medical field, an amino acid sequence refers to the linear order of amino acids in a protein molecule. Proteins are made up of chains of amino acids, and the specific sequence of these amino acids determines the protein's structure and function. The amino acid sequence is determined by the genetic code, which is a set of rules that specifies how the sequence of nucleotides in DNA is translated into the sequence of amino acids in a protein. Each amino acid is represented by a three-letter code, and the sequence of these codes is the amino acid sequence of the protein. The amino acid sequence is important because it determines the protein's three-dimensional structure, which in turn determines its function. Small changes in the amino acid sequence can have significant effects on the protein's structure and function, and this can lead to diseases or disorders. For example, mutations in the amino acid sequence of a protein involved in blood clotting can lead to bleeding disorders.

Recombinant proteins are proteins that are produced by genetically engineering bacteria, yeast, or other organisms to express a specific gene. These proteins are typically used in medical research and drug development because they can be produced in large quantities and are often more pure and consistent than proteins that are extracted from natural sources. Recombinant proteins can be used for a variety of purposes in medicine, including as diagnostic tools, therapeutic agents, and research tools. For example, recombinant versions of human proteins such as insulin, growth hormones, and clotting factors are used to treat a variety of medical conditions. Recombinant proteins can also be used to study the function of specific genes and proteins, which can help researchers understand the underlying causes of diseases and develop new treatments.

Angiostatic proteins are a group of proteins that regulate blood vessel formation, also known as angiogenesis. They play a crucial role in maintaining the balance between blood vessel growth and regression, which is essential for normal tissue development, wound healing, and tumor growth. Angiostatic proteins can either promote or inhibit angiogenesis, depending on the context and the specific protein involved. Some examples of angiostatic proteins include thrombospondin-1, endostatin, and angiostatin. Thrombospondin-1 is a large extracellular matrix protein that inhibits angiogenesis by binding to and blocking the activity of several pro-angiogenic growth factors, such as vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). Endostatin is a fragment of collagen XVIII that inhibits angiogenesis by binding to and activating the receptor for VEGF, preventing it from binding to its target cells and promoting blood vessel growth. Angiostatin is a proteolytic fragment of plasminogen that inhibits angiogenesis by blocking the activity of several pro-angiogenic growth factors, including VEGF and basic fibroblast growth factor (bFGF). Overall, angiostatic proteins play a critical role in regulating blood vessel formation and are important targets for the development of anti-angiogenic therapies for various diseases, including cancer, cardiovascular disease, and age-related macular degeneration.

CD8-positive T-lymphocytes, also known as cytotoxic T-cells, are a type of white blood cell that plays a crucial role in the immune system's response to infections and diseases. These cells are a subtype of T-lymphocytes, which are a type of immune cell that plays a central role in cell-mediated immunity. CD8-positive T-lymphocytes are characterized by the presence of a protein called CD8 on their surface, which helps them to recognize and bind to infected cells or cancer cells. Once bound, these cells release toxic substances that can kill the infected or cancerous cells. CD8-positive T-lymphocytes are an important part of the immune system's response to viral infections, such as HIV and herpes, and to some types of cancer. They are also involved in the immune response to bacterial infections and in the regulation of immune responses to prevent autoimmune diseases. In the medical field, CD8-positive T-lymphocytes are often studied as a way to understand the immune system's response to infections and diseases, and to develop new treatments for these conditions.

Coculture techniques refer to the process of growing two or more different cell types together in a single culture dish or flask. This is commonly used in the medical field to study interactions between cells, such as how cancer cells affect normal cells or how immune cells respond to pathogens. Coculture techniques can be used in a variety of ways, including co-culturing cells from different tissues or organs, co-culturing cells with different cell types, or co-culturing cells with microorganisms or other foreign substances. Coculture techniques can also be used to study the effects of drugs or other treatments on cell interactions. Overall, coculture techniques are a valuable tool in the medical field for studying cell interactions and developing new treatments for diseases.
