Catecholamines 158-172 vasoactive intestinal peptide Gallus gallus 52-55 10974664-5 2000 Thus, this is the first study to demonstrate a direct stimulatory role for VIP or PACAP in catecholamine secretion from piscine chromaffin cells. Catecholamines 91-104 vasoactive intestinal peptide Gallus gallus 75-78
