Psychedelics can reverse neuroimmune interactions that boost fear

A new study suggests that fear and the immune system are connected in previously unknown ways. Researchers found that the immune system can influence stress and fear behaviors by changing how brain cells communicate.

Psychedelics May Reverse Effects of Neuroimmune Interactions That Drive Fear Responses

A newly reported study suggests that fear and the immune system are connected in previously unknown ways. Results from the preclinical research, headed by scientists at Mass General Brigham, showed that interactions between immune and brain cells drive fear responses, and suggest that treatment with psychedelics such as 3,4-methylenedioxymethamphetamine (MDMA), or psilocybin, may reverse these effects. Collective findings from the study, includi…

Study Reveals Psychedelics Can Reverse Neuroimmune Mechanisms That Amplify

Groundbreaking research from Mass General Brigham has illuminated a fascinating new dimension in the interplay between the immune system and the brain, revealing how this communication network profoundly influences fear and stress responses. The study, recently published in Nature, delves into previously uncharted territory, suggesting that immune cell activity within the brain can modulate emotional behaviors associated with fear—and, crucially…

Harvard Study: Psychedelics Can Reverse Fear Behavior by Targeting Brain-Immune Pathways

The Marijuana Herald - Marijuana news and information A new study published in Nature by researchers at Harvard Medical School has found that psychedelic compounds can reduce stress-induced fear responses by altering neuroimmune activity in the brain. The research highlights a mechanism in which astrocytes—cells in the amygdala involved in emotional processing—help regulate fear through the epidermal growth factor receptor (EGFR). The study foun…
