Sigma-1 receptor activation mediates a faster antidepressant-like effect through disinhibition of the DRN5-HT-mPFCpyr neural circuit via S1R/5-HT1AR heterocomplex.
BACKGROUND The Sigma-1 receptor (S1R) represents a promising target for faster-onset antidepressants. Nevertheless, the mechanism underlying the delayed onset of therapeutic action exhibited by S1R-activating selective serotonin reuptake inhibitors (SSRIs) remains unclear. Thus, elucidating the role of S1R in mediating...
