{wiki=Ligand_dependent_pathway}
A ligand-dependent pathway refers to a signaling mechanism in which the binding of a specific ligand (usually a molecule such as a hormone, neurotransmitter, or other signaling substance) to its corresponding receptor triggers a cascade of biological responses within a cell. This pathway is characterized by the requirement for the ligand to bind to the receptor in order for the signaling event to occur.
