Glucose and carbachol synergistically stimulate phosphatidic acid accumulation in pancreatic islets

Phosphatidic acid has been previously implicated as an intracellular mediator of insulin secretion. Very little is known, however, about endogenous phosphatidic acid levels in islets. We now show, for the first time, that glucose and carbachol, at concentrations which stimulate insulin secretion, si...
