WebDistance isn't really the most important difference between paracrine and endocrine signaling and to my knowledge isn't clearly defined. Paracrine signaling molecules typically degrade or get absorbed very quickly, so if I had to guess I'd say they often only reach neighboring cells (e.g. in synapses) and reported can reach cells that are within a few … WebParacrine signaling acts on nearby cells, endocrine signaling uses the circulatory system to transport ligands, and autocrine signaling acts on the signaling cell.

WebAutocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell. [1] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
