High Fidelity Messenger Molecules

Meaning

High Fidelity Messenger Molecules refers to signaling compounds, such as specific hormones or neurotransmitters, that transmit biological information with minimal degradation or alteration across the signaling cascade. This fidelity ensures that the intended physiological response at the target cell accurately reflects the initial stimulus from the endocrine gland or neural center. Maintaining this high quality of signaling is essential for precise homeostatic control and appropriate physiological adaptation. When fidelity drops, downstream responses become noisy or inaccurate, mimicking dysfunction.
