Receptor Dynamics

Meaning

Receptor dynamics describes the continuous, adaptive process involving the synthesis, insertion, trafficking, internalization, and degradation of cellular receptors in response to internal and external stimuli. This regulatory process dictates the sensitivity of a target cell to a specific hormone or neurotransmitter signal at any given moment. Alterations in receptor dynamics, such as down-regulation due to chronic overstimulation, are a common cause of cellular resistance and hormonal imbalance, profoundly impacting therapeutic outcomes.
