Gaba receptor downregulation
WebThe elucidation of the precise mechanisms underlying the downregulation of GABA B receptors under pathological conditions provides the opportunity to define starting points for the development of therapeutic interventions, which specifically target the receptors in the diseased neurons. WebJul 21, 2024 · This phenomenon, known as "down regulation", means that the number of "high affinity" GABA receptors decreases in response to the enhancement of GABA caused by the drug. Such homeostatic responses, which tend to reinstate the status quo despite the continued presence of drug, happen with many of the drugs that people take …
