ABSTRACT Schizophrenia (SCZ) is increasingly linked to neuroimmune dysregulation and impaired synaptic plasticity, yet the cellular mechanisms connecting inflammatory signaling to neural dysfunction remain poorly understood. Using human induced pluripotent stem cell (iPSC)-derived cortical spheroids (hCS) and astrocytes from patients with SCZ and matched controls, we investigated the effects of...
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...
N,N-dimethyltryptamine (DMT) is a potent endogenous hallucinogen present in the brain of humans and other mammals. Despite extensive research, its physiological role remains largely unknown. Recently, DMT has been found to activate the sigma-1 receptor (Sig-1R), an intracellular chaperone fulfilling an interface role between the endoplasmic reticulum (ER) and mitochondria. It ensures the...
