Autocrine Signaling
Definition
Autocrine signaling is a form of cell communication in which a cell produces and releases signals that bind to receptors on its own surface, leading to changes within the same cell.
Analogy
Think of autocrine signaling like writing yourself a reminder note. You're both the sender (writing the note) and receiver (reading and acting upon it).
