Abstract

Sigma-1 receptors (Sig-1Rs) have been implicated in many neurological and psychiatric conditions. Sig-1Rs are intracellular chaperones that reside specifically at the endoplasmic reticulum (ER)-mitochondrion interface, referred to as the mitochondrion-associated ER membrane (MAM). Here, Sig-1Rs regulate ER-mitochondrion Ca(2+) signaling. In this review, we discuss the current understanding of Sig-1R functions. Based on this, we suggest that the key cellular mechanisms linking Sig-1Rs to neurological disorders involve the translocation of Sig-1Rs from the MAM to other parts of the cell, whereby Sig-1Rs bind and modulate the activities of various ion channels, receptors, or kinases. Thus, Sig-1Rs and their associated ligands may represent new avenues for treating aspects of neurological and psychiatric diseases.

  • Activation of S1R by DMT has been suggested to stimulate synaptic plasticity in addition to 5-HT2AR-induced modulation and is likely responsible for ayahuasca's antidepressant effects.

    “Activation of S1R by DMT has been suggested to stimulate synaptic plasticity in addition to 5-HT2AR-induced modulation and is likely responsible for ayahuasca's antidepressant effects (64, 102).”

    From Psychedelics and Neuroplasticity: A Systematic Review Unraveling the Biological Underpinnings of Psychedelics. (2021) · cites this paper as [64]

    The Voltage-gated Na+ channels section identifies DMT as a sigma-1 receptor ligand, and the Ligand-gated channels section describes sigma-1 receptor modulation of synaptic transmission and plasticity. But these passages do not show that DMT stimulates synaptic plasticity through that receptor. The cited paper also does not connect this mechanism to 5-HT2A modulation or attribute ayahuasca’s antidepressant effects to it (page numbers unavailable). (LLM, conf=0.87)

  • Selective silencing of the sigma-1 receptor decreased the survival of iPSCs by 93%, indicating that the S1R mediated the DMT-induced survival.

    “Moreover, selective silencing of the plasticity-promoting intracellular sigma-1 receptor (S1R) (64) decreased the survival of iPSCs by 93%, indicating that the S1R mediated the DMT-induced survival (42).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
