Hormone Receptor Saturation

Meaning

Hormone Receptor Saturation is the physiological state in which a maximum number of specific hormone receptors on the surface or within a target cell are occupied by their corresponding hormone ligands. Once saturation is achieved, increasing the concentration of the hormone will no longer elicit a greater biological response, defining a ceiling effect for that particular signal transduction pathway. Clinically, this parameter informs the effective therapeutic dose limit.
