What is the Origin of Receptor Desensitization?

This mechanism is a core concept in cellular pharmacology and signal transduction studies, describing how biological systems manage continuous input. In endocrinology, it explains why continuous high levels of a hormone can eventually lead to diminished cellular effect, even if circulating levels remain high. The origin is rooted in understanding cellular homeostasis limits.

What is the Mechanism of Receptor Desensitization?

Desensitization often involves post-translational modifications of the receptor protein, such as phosphorylation, which can lead to receptor internalization or decoupling from its associated G-protein or second messenger system. For instance, chronic high insulin exposure can lead to decreased translocation of GLUT4 transporters due to receptor modifications. This dampening effect requires the signaling intensity to be reduced or the ligand concentration lowered to restore full cellular sensitivity.

Receptor Desensitization

Meaning

Receptor Desensitization is a physiological process where target cells reduce their responsiveness to a signaling molecule, such as a hormone or neurotransmitter, following prolonged or excessive exposure to that ligand. This mechanism serves to protect the cell from overstimulation and maintain dynamic range within the signaling pathway. It is a fundamental form of cellular adaptation observed across the endocrine system.
