Selective, α2β1 integrin-dependent secretion of il-6 by connective tissue mast cells.
Mast cells, critical mediators of inflammation and anaphylaxis, are poised as one of the first lines of defense against external assault. Mast cells release several classes of preformed and de novo synthesized mediators. Cross-linking of the high-affinity FcεRI results in degranulation and the release of preformed, proinflammatory mediators including histamine and serotonin. We previously demon...
متن کاملChondroitin sulphate inhibits connective tissue mast cells.
1. Mast cells derive from the bone marrow and are responsible for the development of allergic and possibly inflammatory reactions. Mast cells are stimulated by immunoglobulin E (IgE) and specific antigen, but also by a number of neuropeptides such as neurotensin (NT), somatostatin or substance P (SP), to secrete numerous pro-inflammatory molecules that include histamine, cytokines and proteolyt...
متن کاملIL-1 induces vesicular secretion of IL-6 without degranulation from human mast cells.
Fc epsilon RI cross-linkage in mast cells results in release of granule-associated mediators, such as histamine and proteases, as well as the production of numerous cytokines, including IL-6. Mast cells have been increasingly implicated in inflammatory processes where explosive degranulation is not commonly observed. Here, we show that IL-1 stimulates secretion of IL-6 without release of the gr...
متن کاملCloning of the cDNA and gene of mouse mast cell protease-6. Transcription by progenitor mast cells and mast cells of the connective tissue subclass.
The cDNA and gene for mouse mast cell protease-6 (MMCP-6) have been sequenced and show MMCP-6 to be translated as a prepro-enzyme with a 21-amino acid hydrophobic leader peptide, a 10-amino acid activation peptide, and a 245-amino acid mature enzyme. The mature form of the enzyme has 73% amino acid sequence identity with human and dog mast cell tryptases. The MMCP-6 gene includes 6 exons, with ...
متن کاملMast cells in the inflammatory connective tissue diseases
Objective: To detect mast cells in normal human skin and mast cell infiltration in skin biopsies in patients with systemic sclerosis, systemic lupus erythematosus, Raynaud’s phenomenon, and persons not suffering from any systemic disease. Material and methods: Paraffin histological sections were stained with toluidine blue and by immunoperoxidase method for the von Willebrand factor. Results: I...
