Histamine secretion from mast cells stimulated with bradykinin
- 81 Downloads
Bradykinin and a range of peptide analogues induced a dose-dependent release of histamine from rat peritoneal mast cells. The characteristics of the release were not consistent with the involvement of defined bradykinin receptors but indicated that the peptide acted through the putative mast cell polyamine receptor. Consistently, the effect of bradykinin was largely confined to serosal mast cells of the rat and hamster, while human histaminocytes were essentially unresponsive. These data do then not support a general role for kinin-induced activation of mast cells in human allergic disease.
