How would you define a ligand in cell-to cell signalling?

In cell-to-cell signaling, a ligand is a molecule that plays a crucial role in transmitting information between cells. Ligands are typically small molecules or proteins that can bind to specific receptors on the surface of target cells, initiating a cellular response. The binding of a ligand to its corresponding receptor is a fundamental mechanism by which cells communicate with each other in various physiological processes and signaling pathways.

Here's a more detailed breakdown of the key characteristics of ligands in cell-to-cell signaling:
