The clinical strategy of increasing the sensitivity of target cells and tissues to the signaling molecules, particularly hormones, growth factors, and neurotransmitters, that are present in the systemic circulation. Diminished cellular responsiveness, often due to receptor downregulation or post-receptor signaling defects, is a hallmark of aging and metabolic dysfunction, such as insulin resistance. Enhancement seeks to maximize the biological effect of endogenous and administered compounds.
Origin
This concept is central to modern endocrinology and molecular physiology, recognizing that hormone action is dictated by receptor function and intracellular signal transduction efficiency, not merely by the concentration of the hormone itself. It represents a sophisticated evolution of treatment paradigms that addresses the quality of the cellular dialogue.
Mechanism
Enhancement mechanisms often target the cellular membrane and intracellular machinery. This can involve improving membrane fluidity through essential fatty acid supplementation, upregulating specific receptor expression via exercise or nutritional signals, or improving mitochondrial health to provide sufficient energy for signal transduction. By correcting underlying cellular environment issues, the target cell is rendered more receptive to its physiological messengers, leading to a stronger and more efficient biological response to hormonal cues.
