Cellular Responsiveness Enhancement

Meaning

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.
