1955-P: Interleukin-1ß Orchestrates Non–Glucose Dependent Cephalic Phase Insulin Release in Health and Obesity

The non-glucose dependent spike in insulin levels immediately following the beginning of a meal is called the cephalic or pre-absorptive phase of insulin secretion. Even though this early insulin response is of marked consequence for overall postprandial insulin release, its basic mechanisms remain largely unexplored. Here, we show that both genetic and pharmacologic blockade of interleukin-1β (IL-1β) leads to a pronounced reduction in cephalic...
