1 ET-1 induced a very rapid (< or = 1 min) and dose-dependent release of histamine and serotonin from BMMC cultured in the presence of both IL-3 and IL-4. Histamine interleukin 4 Mus musculus
2 In BMMC, the histamine and serotonin release induced by ET-1 (10(-6) M) was inhibited by an ETA-R-specific antagonist (cyclic [D-Asp-Pro-D-Val-Leu-D-Trp]) in a dose-dependent manner, with complete inhibition at an antagonist concentration of 10(-8) M. ET-1 stimulated leukotriene C4 biosynthesis up to 4.5-fold in BMMC cultured in the presence of IL-4. Histamine interleukin 4 Mus musculus
