DMT, an endogenous agonist of the sigma-1 receptor (Sig-1R) in addition to its serotonin receptor actions, shows therapeutic potential for neuroprotection against ischemia-reperfusion injury (IRI) and neurodegenerative disorders. Sigma-1 receptors are highly expressed in the brain and spinal cord and are implicated in central nervous system disorders. Previous theoretical and experimental work suggests targeting sigma and serotonin receptors via DMT may treat conditions like stroke, global brain ischemia, Alzheimer's disease, and amyotrophic lateral sclerosis. The paper reviews Sig-1R's role in cellular bioenergetics related to IRI and summarizes preclinical DMT studies that mitigated IRI and related neuropathologies. DMT's effect may involve universal cellular protective mechanisms, positioning it as a model molecule for developing treatments for neurodegenerative disorders.
