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.
In this type of signaling, messages are passed directly from one adjacent cell to another through contact or shared junctions. It's like passing a note hand-to-hand in class.
