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...
Post-traumatic stress disorder (PTSD) is associated with cognitive deficits, oxidative stress, and inflammation. Animal models have recapitulated features of PTSD, but no comparative RNA sequencing analysis of differentially expressed genes (DEGs) in the brain between PTSD and animal models of traumatic stress has been carried out. We compared DEGs from the prefrontal cortex (PFC) of an...
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...
