Common genetic variations in a particular serotonin receptor could be responsible for the varying effects psychedelic drugs have on different individuals, according to a recently published study from researchers at the University of North Carolina. The study, which comes at a time of reinvigorated research into the potential therapeutic benefits of psychedelic drugs, could shed light on why the substances seem to have dramatically positive effects for some patients with serious mental health conditions while others find little therapeutic value in the drugs.
Bryan Roth, MD, PhD, led a team of researchers at the University of North Carolina (UNC) to complete the study. The goal of the research was to explore how variations in this one serotonin receptor changes the activity of four psychedelic therapies. The laboratory research in cells showed that seven variants uniquely and differentially impact the receptor’s response to four psychedelic drugs—psilocin, LSD, 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) and mescaline. The researchers believe that the in vitro research could be useful for determining appropriate mental health therapies for patients.
“Based on our study, we expect that patients with different genetic variations will react differently to psychedelic-assisted treatments,” said Roth, who leads the National Institutes of Health Psychotropic Drug Screening Program. “We think physicians should consider the genetics of a patient’s serotonin receptors to identify which psychedelic compound is likely to be the most effective treatment in future clinical trials.”
Psychedelics and Mental Health
Research published in 2020 in the journal JAMA Psychiatry found that psilocybin-assisted psychotherapy was a quick-acting and effective treatment for a group of 24 participants with major depressive disorder. A separate study published in 2016 determined that psilocybin treatment produced substantial and sustained decreases in depression and anxiety in patients with life-threatening
