Melatonin excitotoxicity kinate receptors
Web11 dec. 2024 · NMDA receptors also appear to have involvement in a process called excitotoxicity. Excitotoxicity may play a role in the pathophysiology of a variety of diseases such as epilepsy or Alzheimer disease. Many drugs inhibit NMDA receptors, including ketamine and phencyclidine, two common drugs of abuse. Go to: Cellular Level
