Paracrine signaling's a form of cell signaling in which the target cell's near ("para" = near) the signal-releasing cell. A distinction's sometimes made between paracrine and autocrine signaling. Both affect neighboring cells; but, whereas autocrine signaling occurs among the same cell, paracrine signaling affects other cells. Two neurons would be an example of a paracrine signal. Local action Some signaling molecules degrade very quickly, limiting the scope of their effectiveness to the immedia… (More on Paracrine)
