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.
Best Answer: Paracrine signaling is a form of cell signaling in which the target cell is close to (para = alongside of or next to, but this strict prefix definition is not meticulously followed here) the signal releasing cell. The signal chemical is called the paracrine agent or paracrine hormone. The distinction is sometimes made between paracrine and autocrine signaling. In both types of signalling, the signal is limited to other cells in the local area.
