What is the Meaning of Receptor Upregulation?

Receptor Upregulation is the biological process where a cell increases the number of specific hormone receptors expressed on its surface or within the cytoplasm in response to prolonged exposure to low concentrations of the ligand or following chronic blockade of the receptor. This compensatory mechanism aims to restore cellular sensitivity to the signaling molecule. It reflects cellular adaptation to altered hormonal milieu.

What is the Origin of Receptor Upregulation?

Combining receptor with up and regulare (to guide), signifying an increase in the regulatory reception machinery.

What is the Mechanism of Receptor Upregulation?

This involves increased gene transcription and translation rates for the receptor protein, often mediated by intracellular signaling pathways responding to low agonist presence. If a target tissue experiences chronic low levels of a vital hormone, the cell attempts to maximize signal capture by synthesizing more docking sites. Conversely, chronic high ligand exposure typically leads to downregulation.
