Did you mean Paracrine Function?

GlossaryParacrine Function

cells communicate by releasing signals to nearby cells

Paracrine function refers to a type of cell signaling where a cell produces a signal to induce changes in nearby cells, affecting their behavior or function. Unlike hormones that travel through the bloodstream to distant targets, paracrine signals act locally, ensuring that the response is limited to the immediate cellular environment. This is crucial in processes like wound healing and immune responses.
