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.
A counterregulatory hormone that works against the action of insulin. Most people with diabetes know that insulin is secreted by the beta cells of the pancreas. What many donât know is that other cells in the pancreas called alpha cells secrete the hormone glucagon. Glucagon is one of the counterregulatory hormones that helps the body regulate blood glucose levels. In people who donât have diabetes, when blood glucose levels fall, the beta cells secrete less insulin. In addition, the alpha cells secrete more glucagon.
