Cellular Signal Fidelity

Meaning

Cellular Signal Fidelity refers to the accuracy and reliability with which a cell transduces an external stimulus, such as a hormone or nutrient signal, into a precise and appropriate intracellular response. High fidelity ensures that the intended downstream effect, like gene expression or enzyme activation, occurs exactly as dictated by the initial molecular message. Deviation from this accuracy suggests pathway interference or receptor impairment.
