Physiological Signaling Fidelity

Meaning

Physiological Signaling Fidelity refers to the accuracy, precision, and clarity with which chemical messengers, such as hormones, neurotransmitters, and cytokines, transmit information between cells and organ systems throughout the body. High fidelity ensures that the intended biological signal is received and correctly interpreted by the target cell, leading to the appropriate and robust physiological response. Loss of fidelity, often due to receptor down-regulation, chronic inflammation, or metabolic clutter, results in impaired communication and is a core driver of systemic dysfunction and age-related decline. Maintaining this fidelity is paramount for effective homeostatic control.
