The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. 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. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. 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.

They generally act locally in a paracrine or autocrine rather than endocrine manner.
NIH 3T3 Cells
A continuous cell line of high contact-inhibition established from NIH Swiss mouse embryo cultures. The cells are useful for DNA transfection and transformation studies. (From ATCC [Internet]. Virginia: American Type Culture Collection; c2002 [cited 2002 Sept 26]. Available from http://www.atcc.org/)
Lymphocyte Function-Associated Antigen-1

Domesticated bovine animals of the genus Bos, usually kept on a farm or ranch and used for the production of meat or dairy products or for heavy labor.
Mesenchymal Stromal Cells
Bone-marrow-derived, non-hematopoietic cells that support HEMATOPOETIC STEM CELLS. They have also been isolated from other organs and tissues such as UMBILICAL CORD BLOOD, umbilical vein subendothelium, and WHARTON JELLY. These cells are considered to be a source of multipotent stem cells because they include subpopulations of mesenchymal stem cells.
Enzyme-Linked Immunosorbent Assay
An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
Protein Structure, Tertiary
The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.

An integrin found in FIBROBLASTS; PLATELETS; MONOCYTES, and LYMPHOCYTES. Integrin alpha5beta1 is the classical receptor for FIBRONECTIN, but it also functions as a receptor for LAMININ and several other EXTRACELLULAR MATRIX PROTEINS.
MAP Kinase Signaling System
An intracellular signaling system involving the MAP kinase cascades (three-membered protein kinase cascades). Various upstream activators, which act in response to extracellular stimuli, trigger the cascades by activating the first member of a cascade, MAP KINASE KINASE KINASES; (MAPKKKs). Activated MAPKKKs phosphorylate MITOGEN-ACTIVATED PROTEIN KINASE KINASES which in turn phosphorylate the MITOGEN-ACTIVATED PROTEIN KINASES; (MAPKs). The MAPKs then act on various downstream targets to affect gene expression. In mammals, there are several distinct MAP kinase pathways including the ERK (extracellular signal-regulated kinase) pathway, the SAPK/JNK (stress-activated protein kinase/c-jun kinase) pathway, and the p38 kinase pathway. There is some sharing of components among the pathways depending on which stimulus originates activation of the cascade.
Protein-Tyrosine Kinases
Protein kinases that catalyze the PHOSPHORYLATION of TYROSINE residues in proteins with ATP or other nucleotides as phosphate donors.
Integrin alpha4
An integrin alpha subunit that is unique in that it does not contain an I domain, and its proteolytic cleavage site is near the middle of the extracellular portion of the polypeptide rather than close to the membrane as in other integrin alpha subunits.

It is involved in both cell-cell and cell- EXTRACELLULAR MATRIX adhesion and plays a role in INFLAMMATION, hematopoietic cell homing and immune function, and has been implicated in skeletal MYOGENESIS; NEURAL CREST migration and proliferation, lymphocyte maturation and morphogenesis of the PLACENTA and HEART.
Embryo, Nonmammalian
The developmental entity of a fertilized egg (ZYGOTE) in animal species other than MAMMALS. For chickens, use CHICK EMBRYO.
Antigens, CD44
Acidic sulfated integral membrane glycoproteins expressed in several alternatively spliced and variable glycosylated forms on a wide variety of cell types including mature T-cells, B-cells, medullary thymocytes, granulocytes, macrophages, erythrocytes, and fibroblasts. CD44 antigens are the principle cell surface receptors for hyaluronate and this interaction mediates binding of lymphocytes to high endothelial venules. (From Abbas et al., Cellular and Molecular Immunology, 2d ed, p156)

Activation of protein tyrosine kinases and matrix metalloproteinases causes blood-brain barrier injury: Novel mechanism for neurodegeneration associated with alcohol abuse. (1/45)

Blood-brain barrier (BBB) formed by brain microvascular endothelial cells (BMVEC) regulates the passage of molecules and leukocytes in and out of the brain. Activation of matrix metalloproteinases (MMPs) and alteration of basement membrane (BM) associated with BBB injury was documented in stroke patients. While chronic alcoholism is a risk factor for developing stroke, underlying mechanisms are not well understood. We hypothesized that ethanol (EtOH)-induced protein tyrosine kinase (PTK) signaling resulted a loss of BBB integrity via MMPs activation and degradation of BM component, collagen IV. Treatment of BMVEC with EtOH or acetaldehyde (AA) for 2-48 h increased MMP-1, -2 and -9 activities or decreased the levels of tissue inhibitors of MMPs (TIMP-1, -2) in a PTK-dependent manner without affecting protein tyrosine phosphatase activity. Enhanced PTK activity after EtOH exposure correlated with increased phosphorylated proteins of selective receptor and nonreceptor PTKs. Up-regulation of MMPs activities and protein contents paralleled a decrease in collagen IV content, and inhibitors of EtOH metabolism, MMP-2 and -9, or PTK reversed all these effects. Using human BMVEC assembled into BBB models, we found that EtOH/AA diminished barrier tightness, augmented permeability, and monocyte migration across the BBB via activation of PTKs and MMPs. These findings suggest that alcohol associated BBB injury could be mediated by MMPs via BM protein degradation and could serve as a comorbidity factor for neurological disorders like stroke or neuroinflammation. Furthermore, our preliminary experiments indicated that human astrocytes secreted high levels of MMP-1 and -9 following exposure to EtOH, suggesting the role of BM protein degradation and BBB compromise as a result of glial activation by ethanol. These results provide better understanding of multifaceted effects of alcohol on the brain and could help develop new therapeutic interventions.  (+info)

Neutrophil interactions with keratocytes during corneal epithelial wound healing: a role for CD18 integrins. (2/45)

PURPOSE: To determine the role of keratocytes and leukocyte beta(2) (CD18) integrins in neutrophil (PMN) migration through the corneal stroma after epithelial scrape injury. METHODS: Using C57BL/6 wild-type and CD18(-/-) mice, corneas were excised at 6 hours (wild-type) or 24 hours (CD18(-/-)) after central corneal epithelial abrasion, time points determined previously to have similar levels of emigrated PMNs. Corneas were prepared for ultrastructural morphometric analysis of PMNs, keratocyte networks, and collagen. RESULTS: Transmission electron microscopy revealed intact keratocyte networks within the paralimbus that were morphometrically similar, regardless of epithelial injury or mouse genotype. Secondary to epithelial abrasion, extravasated PMNs within the paralimbus developed close contacts with keratocytes and collagen. In wild-type mice, 40% of the PMN surface was in contact with the keratocyte surface, and this value decreased to 10% in CD18(-/-) mice. PMN contact with collagen was similar in wild-type and CD18(-/-) mice, with approximately 50% of the PMN surface contacting the collagen fibrils. Since corneal edema resulting from scrape injury was similar, regardless of genotype and did not involve structural changes in collagen fibrils, these data favor a direct role for CD18 in mediating PMN contact with keratocytes. CONCLUSIONS: The data show that in response to epithelial scrape injury, PMN migration in the corneal stroma involves close contact between keratocytes and collagen. Although PMN-keratocyte contacts require CD18 integrins, contact with collagen is CD18 independent. Fundamentally, PMN migration along keratocyte networks constitutes the beginning of a new experimental concept for understanding leukocyte migration within the wounded cornea.  (+info)

STAT1 signaling modulates HIV-1-induced inflammatory responses and leukocyte transmigration across the blood-brain barrier. (3/45)

The relationship among neuroinflammation, blood-brain barrier (BBB) dysfunction, and progressive HIV-1 infection as they affect the onset and development of neuroAIDS is incompletely understood. One possible link is signal transducers and activators of transcription (STATs) pathways. These respond to proinflammatory and regulatory factors and could affect neuroinflammatory responses induced from infected cells and disease-affected brain tissue. Our previous works demonstrated that HIV-1 activates pro-inflammatory and interferon-alpha-inducible genes in human brain microvascular endothelial cells (HBMECs) and that these genes are linked to the Janus kinase (JAK)/STAT pathway. We now demonstrate that HIV-1 activates STAT1, induces IL-6 expression, and diminishes expression of claudin-5, ZO-1, and ZO-2 in HBMECs. The STAT1 inhibitor, fludarabine, blocked HIV-1-induced IL-6, diminished HIV-1-induced claudin-5 and ZO-1 down-regulation, and blocked HIV-1- and IL-6-induced monocyte migration across a BBB model. Enhanced expression and activation of STAT1 and decreased claudin-5 were observed in microvessels from autopsied brains of patients with HIV-1-associated dementia. These data support the notion that STAT1 plays an integral role in HIV-1-induced BBB damage and is relevant to viral neuropathogenesis. Inhibition of STAT1 activation could provide a unique therapeutic strategy to attenuate HIV-1-induced BBB compromise and as such improve clinical outcomes.  (+info)

Immunomodulation by alpha(1)-proteinase inhibitor: lack of chemotactic effects of recombinant human alpha(1)-proteinase inhibitor from yeast on human peripheral blood granulocytes. (4/45)

INTRODUCTION: Recombinant alpha(1)-proteinase inhibitor, clinically developed for inhalative augmentation therapy in patients with alpha(1)-proteinase inhibitor deficiency or cystic fibrosis, may directly contribute to leukocyte accumulation as it may function as a chemoattractant. The migratory effects of yeast-derived human recombinant alpha(1)-proteinase inhibitor on human peripheral blood neutrophils and eosinophils were therefore tested in vitro. MATERIALS AND METHODS: Human peripheral blood leukocytes were prepared from forearm venous blood and tested for migration toward various preparations of yeast-derived recombinant alpha(1)-proteinase inhibitor in modified Boyden-chamber micropore filter assays. RESULTS: No direct effects of yeast-derived recombinant human alpha(1)-proteinase inhibitor on in vitro migration of isolated neutrophils or eosinophils were seen. CONCLUSIONS: The lack of direct chemotactic effects of recombinant human alpha(1)-proteinase inhibitor despite anti-inflammatory effects in other biological activities of leukocytes may contribute to the preserved antibacterial defense mechanisms observed in patients under experimental augmentation therapy with inhaled alpha(1)-proteinase inhibitor.  (+info)

C-terminal repeats of Clostridium difficile toxin A induce production of chemokine and adhesion molecules in endothelial cells and promote migration of leukocytes. (5/45)

The C-terminal repeating sequences of Clostridium difficile toxin A (designated ARU) are homologous to the carbohydrate-binding domain of streptococcal glucosyltransferases (GTFs) that were recently identified as potent modulins. To test the hypothesis that ARU might exert a similar biological activity on endothelial cells, recombinant ARU (rARU), which was noncytotoxic to cell cultures, was analyzed using human umbilical vein endothelial cells. The rARU could bind directly to endothelial cells in a serum- and calcium-dependent manner and induce the production of interleukin-6 (IL-6), IL-8, and monocyte chemoattractant protein 1 in a dose-dependent manner. An oligosaccharide binding assay indicated that rARU, but not GTFC, binds preferentially to Lewis antigens and 3'HSO3-containing oligosaccharides. Binding of rARU to human endothelial or intestinal cells correlated directly with the expression of Lewis Y antigen. Bound rARU directly activated mitogen-activated protein kinases and the NF-kappaB signaling pathway in endothelial cells to release biologically active chemokines and adhesion molecules that promoted migration in a transwell assay and the adherence of polymorphonuclear and mononuclear cells to the endothelial cells. These results suggest that ARU may bind to multiple carbohydrate motifs to exert its biological activity on human endothelial cells.  (+info)

Comparative study of the usefulness of the drug-induced lymphocyte stimulation test and the leukocyte migration test in drug allergies. (8/45)

In 133 patients suspected of hypersensitivity to drugs and 102 control patients without hypersensitivity to drugs, the identification of allergenic drugs was performed by the drug-induced lymphocyte stimulation test (DLST) and the leukocyte migration test (LMT) to compare their usefulness in identifying drug allergies. In the 133 subject patients, the positive rate was 24.8% on the DLST and 60.9% on the LMT (agreement rate; 77.4%); thus, the LMT showed a significantly higher positive rate than the DLST (p<0.000001, chi(2)-test). In the 102 control patients, the positive rates on the DLST and LMT were 6.9%. In addition, the LMT showed a higher positive rate than the DLST for many hypersensitivity symptoms such as skin eruptions and hepatic injury, and for many drug efficacy categories of the suspected drugs such as antibacterial drugs, etc. Furthermore, the positive rate of the DLST did not change when adjusted for the patients' serum and sex, while that of the LMT increased when adjusted for the patients' serum and was found to be higher in females than in males. Our findings indicate that the LMT may be more useful than the DLST in identifying the causative drug in drug allergies and that its interpretation is influenced by the patient's serum and sex.  (+info)

N2 - The aim of this paper is to track transmigrating leukocytes via TGV flow estimation. Recent results have shown the advantages of the nonlinear and higher order terms of TGV regularizers, especially in static models for denoising and medical reconstruction. We present TGV-based models for flow estimation with the goal to get an exact recovery of simple intracellular and extracellular flows, as well as its implication on realistic tracking situations for transmigration through barriers. To study and quantify different pathways of transmigrating leukocytes, we use large scale 4D fluorescence live microscopy data in vivo..

Drug Allergies/Sensitivities - swollen, symptoms, Definition, Description, Demographics, Causes and symptoms, DiagnosisDrug Allergies/Sensitivities - swollen, symptoms, Definition, Description, Demographics, Causes and symptoms, Diagnosis
Unlike most other allergens, such as pollen or mold spores, drug molecules often are too small to be detected by the immune system. Smaller drugs such as antibiotics cannot induce an immune response unless they combine with a body cell or a carrier protein in the blood. Furthermore, drug allergies often are caused by the breakdown products or metabolites of the drug rather than by the drug itself. Sometimes the same drug, such as penicillin, can induce different types of allergic reactions. IGE-MEDIATED ALLERGIES Most allergies, including most drug allergies, occur because of a reaction with an immune system antibody called immunoglobulin E (IgE). The first exposure to the drug sensitizes the childs immune system by inducing specialized white blood cells to produce IgE that recognizes the specific drug. On subsequent exposure to the drug, the drug-specific IgE antibodies bind to the drug on the surfaces of certain cells of the immune system. This binding activates the cells to release histamine ...

A Practical Approach to Demystifying Drug Allergy in the Intensive Care Unit. A Review ArticleA Practical Approach to Demystifying Drug Allergy in the Intensive Care Unit. A Review Article
Drug hypersensitivity reaction (DHR) is defined as an immunologically mediated response to a pharmacology agent. Some reactions require prior sensitization and some do not. The interactions between different drugs and the immune system occur by different mechanisms leading to variable clinical features. Some reactions are simple and do not alter patient quality of life. Some are life threatening and require immediate recognition and appropriate therapy. Confirming the diagnosis of DHR is often challenging. The environment in the Intensive care units (ICU) is considered high risk place for DHR development as it offers most of the risk factors. In this review, we offer a delicate combined approach that allows an accurate diagnosis of most of the DHRs encountered in the ICU.
