Insulin secretion is modified by other nutrients, circulating hormones and the autonomic nervous system, as well as local paracrine and autocrine signals. Autocrine signalling involves diffusible molecules that bind to receptors on the same cell from which they have been released.
Insulin is a hormone that helps regulate blood sugar. Together with leptin, it regulates food intake and metabolism, according to a review that appeared in the 2004 issue of the journal Endocrinology. When you eat a carbohydrate-containing meal, your blood sugar rises, signaling your pancreas to release insulin.
