N,N-dimethyltryptamine (DMT) is a hallucinogen found endogenously in human brain that is commonly recognized to target the 5-hydroxytryptamine 2A receptor or the trace amine-associated receptor to exert its psychedelic effect. DMT has been recently shown to bind sigma-1 receptors, which are ligand-regulated molecular chaperones whose function includes inhibiting various voltage-sensitive ion channels. Thus, it is possible that the psychedelic action of DMT might be mediated in part through sigma-1 receptors. Here, we present a hypothetical signaling scheme that might be triggered by the binding of DMT to sigma-1 receptors.
N,N-二甲基色胺(DMT)是一种在人脑中内源性发现的致幻剂,通常认为它作用于5-羟色胺2A受体或痕量胺相关受体以发挥其致幻作用。最近研究表明,DMT能与σ-1受体结合,σ-1受体是一种配体调节的分子伴侣,其功能包括抑制各种电压敏感离子通道。因此,DMT的致幻作用可能部分是通过σ-1受体介导的。在此,我们提出一种可能由DMT与σ-1受体结合触发的假设信号传导机制。
