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.
Glucagon and insulin are the two primary hormones â both produced by the pancreas â that stimulate or depress the level of sugar (glucose) in the blood. Insulin is apparently the less robust of the two, as more than 350 million people suffer from type 2 diabetes alone.
