Psychedelics May Improve Mental Health by Targeting Inflammation, Study Suggests
A new study from the University of California, San Francisco provides a possible explanation for how psychedelics like LSD and psilocybin may ease symptoms of depression and anxiety. Researchers found that psychedelics may reduce inflammation in the brain and body by altering gene activity in immune cells. These findings open a window into how psychedelics might act as both neurological and immunological agents.

Investigating the Immune Connection
The study looked at two powerful psychedelics: lysergic acid diethylamide (LSD) and psilocybin, the active compound in magic mushrooms. Researchers exposed human immune cells to each compound in the lab. They then tracked changes in gene expression using single-cell RNA sequencing. This method allowed the team to measure how specific immune cells reacted at the genetic level.
What they found was striking. Both psychedelics changed the activity of hundreds of genes. Many of the affected genes were linked to inflammation, a known contributor to many mental health disorders. When the psychedelics reduced this activity, researchers began to understand a new mechanism that could be at play.

Beyond the Brain
Much of the public discussion around psychedelics focuses on their effect on brain function. This study adds a new layer by showing that the body’s immune system also plays a role. The compounds did not just dampen inflammation directly. They reprogrammed how immune cells responded to stress and environmental signals.
While this was an in vitro study—meaning it took place outside the human body—the researchers believe their findings support the idea that psychedelics may help restore balance across brain and body systems. Future clinical studies will be needed to confirm these effects in patients.
A Promising Path Forward
Psychedelics remain controversial. But with this kind of cellular-level research, the scientific community continues to gain insight into their potential. These findings suggest that anti-inflammatory pathways may be just as important as the hallucinogenic experience in explaining why psychedelics are showing promise in mental health treatment.
