Serotonergic psychedelics are promising treatments for neuropsychiatric disorders, and their immunomodulatory effects may contribute to their clinical efficacy. However, we lack a systematic review and meta-analysis of these effects across in vitro, in vivo non-human, and human studies. We systematically searched PubMed, EMBASE, Web of Science, PsycINFO, LILACS and ClinicalTrials.gov for all...

Serotonergic psychedelics produce therapeutic effects in clinical trials of diverse neuropsychiatric disorders, and preclinical models of inflammatory, cardiometabolic, and neuropsychiatric diseases. These effects appear largely mediated by the serotonin 5-HT2A receptor (5-HT2AR). How could psychedelics elicit transdiagnostic therapeutic effects through a single receptor across tissues as...

There is unprecedented clinician, industry, and patient interest in the therapeutic development of psychedelic drugs. This is due to a combination of promising clinical trial results, positive media coverage, and the lack of novel pharmacologic treatments for psychiatric disorders in recent decades. However, the field faces a key methodological challenge: masking participants to treatment...

Treatments with the serotonergic psychedelic psilocybin are being investigated for multiple neuropsychiatric disorders. Because many patients with these disorders use selective serotonin reuptake inhibitors (SSRIs), understanding interactions between psilocybin and SSRIs is critical for evaluating the safety, efficacy, and scalability of psilocybin-based treatments. Current knowledge about...

Abstract Post-traumatic stress disorder (PTSD) is associated with cognitive deficits, oxidative stress and inflammation. N,N-dimethyltryptamine (DMT) is a known neuroprotective, antioxidant, anti-inflammatory, and psychoplastogen with antidepressant effects. Therefore, we tested the capacity of DMT, the monoamine oxidase inhibitor (MAOI) harmaline, and “pharmahuasca” (DMT + harmaline) to reduce...
