Target Cells via surface ligands

The phrase "Target Cells via surface ligands" refers to the biological mechanism in which ligands—signaling molecules in the extracellular environment—bind to specific receptors on the surface of target cells, leading to activation of signaling pathways and cellular responses. This is a fundamental concept in cell biology and pharmacology, underlying processes such as immune targeting, hormone action, and many therapeutic interventions, but it is not the name of a specific molecular target or receptor[2][3][5][8]. This entry is incorrect as a therapeutic target since it describes a targeting principle or mechanism rather than a unique, targetable molecule or receptor. If you seek structured information on a specific receptor or molecule involved in ligand-based targeting (for example, "Epidermal growth factor receptor" or "CD20"), please provide that specific name.
