Release of cyclooxygenase products from primary cultures of dog or human tracheal epithelium was measured by radioimmunoassay. In both species, bradykinin, platelet-activating factor (PAF), and A23187 (a calcium ionophore) caused increases in the rate of release of prostaglandin (PG) E2 and smaller increases in PGF2 alpha, 6-keto-PGF1 alpha, and thromboxane B2 output. Isoproterenol, vasoactive intestinal peptide (VIP), methacholine, and leukotrienes C4 and D4 had no effect on release of these cyclooxygenase products. Gas chromatography-mass spectrometry showed that the ratio of PGE2 to PGD2 released from dog cells by A23187 was 30:1. Short-circuit current across dog cells was stimulated by bradykinin, A23187, PAF, VIP, methacholine, and isoproterenol. Only the responses to bradykinin and A23187 were reduced by pretreatment with indomethacin.

D001920 Bradykinin A nonapeptide messenger that is enzymatically produced from KALLIDIN in the blood where it is a potent but short-lived agent of arteriolar dilation and increased capillary permeability. Bradykinin is also released from MAST CELLS during asthma attacks, from gut walls as a gastrointestinal vasodilator, from damaged tissues as a pain signal, and may be a neurotransmitter.
