How Does Paracrine Signaling Work?

Paracrine signaling involves the secretion of chemical messengers, such as cytokines, growth factors, and neurotransmitters, into the extracellular space. These molecules travel short distances to interact with receptors on adjacent cells, initiating a cascade of intracellular events. This process is crucial in tissues where cells need to communicate rapidly and efficiently, such as in the immune system or during wound healing.
