N,N-dimethyltryptamine (DMT) is a psychoactive molecule present in the human brain. DMT is under clinical evaluation as a neuroprotective agent in poststroke recovery. Yet, its mechanism of action remains poorly understood. In a rat transient middle cerebral artery occlusion stroke model, we previously showed that DMT reduces infarct volume. Here, we demonstrate that this effect is accompanied...
Background and purposeN,N-dimethyltryptamine (DMT) is an endogenous ligand of the Sigma 1 receptor (Sig-1R) with documented in vitro cytoprotective properties against hypoxia. Our aim was to demonstrate the in vivo neuroprotective effect of DMT following ischemia-reperfusion injury in the rat brain.MethodsTransient middle cerebral occlusion (MCAO) was induced for 60 min in male Wistar rats...
