Mechanism of Peptide-induced Mast Cell Degranulation
Substance P and other polycationic peptides are thought to stimulate mast cell degranulation via direct activation of G proteins. We investigated the ability of extracellularly applied substance P to translocate into mast cells and the ability of intracellularly applied substance P to stimulate degranulation. In addition, we studied by reverse transcription--PCR whether substance P-specific rec...
متن کاملRIII-dependent Mast Cell Degranulation and Anaphylaxis
In mouse mast cells, both Fc e RI and Fc g RIII are abg 2 tetrameric complexes in which different a chains confer IgE or IgG ligand recognition while the signaling FcR b and g chains are identical. We used primarily noninvasive techniques (changes in body temperature, dye extravasation) to assess systemic anaphylactic responses in nonanesthetized wild-type, Fc e RI a chain 2 / 2 and FcR g chain...
متن کاملInosine Binding Stimulates Mast Cell Degranulation
We investigated the mechanism by which inosine, a metabolite of adenosine that accumulates to . 1 mM levels in ischemic tissues, triggers mast cell degranulation. Inosine was found to do the following: ( a ) compete for [ 125 I] N 6 -aminobenzyladenosine binding to recombinant rat A 3 adenosine receptors (A 3 AR) with an IC 50 of 25 6 6 m M; ( b ) not bind to A 1 or A 2A ARs; ( c ) bind to newl...
متن کاملMast cell degranulation induced by type 1 fimbriated Escherichia coli in mice.
The strategic location of mast cells at the host-environment interface and their ability to release potent mediators of inflammation have suggested that these cells may play a pivotal role in host defense against bacterial infection. The ability of the opportunistic pathogen, Escherichia coli, to induce degranulation of mast cells obtained from the mouse peritoneum was investigated. We determin...
