Cellular Responsiveness

Meaning

Cellular responsiveness is the comprehensive term for the final biological outcome a cell produces after receiving and processing a signal, integrating both receptor binding and the subsequent intracellular signaling cascade. It represents the overall physiological change—such as gene expression, protein synthesis, or glucose uptake—that occurs in reaction to a hormonal stimulus. This is the ultimate metric of a cell’s ability to participate in endocrine communication and maintain systemic balance. Impaired responsiveness signifies a failure to translate a message into action, often contributing to the pathology of hormonal disorders.
