Mammalian cells communicate through various mechanisms to coordinate activities and maintain homeostasis:
- Gap Junctions: Allow direct cytoplasmic connections between adjacent cells for the transfer of ions and small molecules. - Paracrine Signaling: Cells release signaling molecules that affect nearby cells. - Endocrine Signaling: Hormones are released into the bloodstream and affect distant target cells. - Autocrine Signaling: Cells respond to signaling molecules they release themselves.
