receptordeszenzitizációt
Rezeptordeszenzitizierung refers to a cellular process where a cell becomes less responsive to a stimulus. This occurs when a receptor, a protein on the cell surface or within the cell that binds to specific molecules, is exposed to a particular ligand (the molecule that binds to the receptor) for an extended period or at a high concentration. In response to this prolonged or intense stimulation, the cell initiates mechanisms to reduce the number or sensitivity of its receptors.
There are several ways desensitization can happen. One common mechanism is receptor internalization, where the cell
Rezeptordeszenzitizierung is a crucial physiological regulatory mechanism. It prevents cells from being overstimulated, which could be
