Degranulation of rat peritoneal mast cells expressed as percentage of PACAP1–38, which is the strongest mast cell degranulator tested. a Shows the effect of the endogenous peptides PACAP1–38, PACAP1–27, and VIP. b Shows the effect of PACAP1–38 and the fragments PACAP6–38, PACAP16–38, and PACAP28–38. Values are given as means ± SEM of 4–8 experiments. From Baun et al. [82]
