Study Details How General Anesthetics And ‘Benzos’ Act on Receptors in The Brain

September 2, 2020 sarah JonasResearch Results

As you drift into unconsciousness before a surgery, general anesthetic drugs flowing through your blood are putting you to sleep by binding mainly to a protein in the brain called the ɣ-aminobutyric acid type A (GABAA) receptor. Now UT Southwestern scientists have shown exactly how anesthetics attach to the GABAA receptor and alter its three-dimensional structure, and how the brain can tell the difference between anesthetics and the psychoactive drugs known as benzodiazepines – which also bind to the GABAA receptor. The findings were published online today in the journal Nature.
