![]() Target cells are the signal-producing cellsĬell differentiation during early organ development in the embryonic stage Table 1: Difference between Autocrine and Paracrine signalingĭefine autocrine signaling: It refers to self-targeting, i.e., the cell signals produced by the cells bind to the receptors of the same cellsĭefine paracrine signaling: Paracrine signaling is between cells that are closely associated or in the vicinity. Table 1: Differences between Paracrine signaling and autocrine signaling Let us further understand the difference between paracrine signaling and autocrine signaling in depth. This is the primary difference between autocrine and paracrine signaling. In biology, autocrine signaling is when the cell signals (hormones, cytokines, etc.) produced and released by the cell bind to the target receptors present on the same cell. Synaptic signaling is a type of paracrine signaling wherein nerve cells communicate with each other at synapses through neurotransmitters (Figure 1). The signal diffuses out of the cell and travels through an extracellular matrix to reach the target cell. Essentially, two closely associated cells communicate via paracrine signaling. In paracrine signaling, the cell signals travel a shorter distance to reach the receptors present on the neighboring cell surface.
