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.
Glucose-dependent insulinotropic peptide is a hormone released from the small intestine that enhances the release of insulin following the intake of food. It is a member of the family of hormones known as the incretins of which the other main member is the hormone glucagon-like peptide 1. Glucose-dependent insulinotropic peptide is made and secreted mainly from the upper section of the small intestine from a specific type of cell known as the K cell. Its main action occurs in the pancreas where it targets beta cells which produce insulin. Glucose-dependent insulinotropic peptide stimulates the release of insulin from the beta cells in the pancreas in order to maintain low blood sugar levels after eating.
