Summary: Sigma-1 receptors subdue systemic inflammation, which can be lethal, as in the case of septic shock. Mice lacking the endoplasmic reticulum sigma-1 receptor had exacerbated responses to LPS (lipopolysaccharides) or fecal slurry. The antidepressant fluvoxamine can bind sigma-1 and … Continue reading

Abstract: “Selective serotonin reuptake inhibitors (SSRIs) are the most prescribed antidepressants. They regulate serotonergic neurotransmission, but it remains unclear how altered serotonergic neurotransmission may contribute to the SSRI resistance observed in approximately 30% of major depressive disorder (MDD) patients. Patient stratification based on pharmacological responsiveness and the … Continue reading
