Understanding Psychedelics and Their Mechanisms
Psychedelics are psychoactive compounds that induce effects similar to LSD and primarily function as agonists at the 5-HT2A receptor. This receptor plays a significant role in psychopharmacology, with many existing antidepressants working as antagonists. Recent reviews have proposed that psychedelics' binding to the 5-HT2A receptor activates G proteins, leading to downstream molecular changes that enhance neuroplasticity. This alteration in neuroplasticity, particularly through the TRKB receptor and brain-derived neurotrophic factor (BDNF), may provide insights into their therapeutic efficacy, especially for conditions like anxiety and depression.
