Abstract:
The effects of the cholecystokinin A (CCKA) receptor antagonist, L-364,718, and the CCKB receptor antagonist, L-365,260, on CCK-8-stimulated insulin secretion were studied in vivo in the mouse. It was found that CCK-8-stimulated insulin secretion was suppressed by L-364,718 at a low dose level (0.078 mumol/kg). In contrast, L-365,260 caused a partial inhibition of CCK-8-stimulated insulin release only at the high dose level (24 mumol/kg). It is concluded that the CCK-8-stimulated insulin release in vivo is mediated by CCK receptors of the CCKA subtype.
