Question

Quizplus · Accepted Answer

Paracrine signaling involves local mediators, which are molecules that are released by one cell that act on nearby cells. Examples include growth factors and cytokines. Autocrine signaling also involves local mediators, but they act on the same cell that released them. Endocrine signaling involves hormones that travel through the bloodstream to act on distant target cells. Juxtacrine signaling involves cell-to-cell contact, where molecules on one cell's surface interact with receptors on another cell's surface. Synaptic signaling involves neurotransmitters that are released from neurons to act on adjacent cells.
