Cell Signaling and Apoptosis Types of Signaling • A ligand is a molecule that has specificity for a given receptor, and the binding of a ligand to the given receptor causes a change. • There is a wide array of cell ligands: hormones, peptides, sugars, and even small, hydrophobic molecules. • Regardless of its type, a ligand is always specific for the target receptor. This ligand-to-receptor specificity helps to regulate responses in the target cell while not impacting non-target cell...
