赛洛西宾治疗难治性抑郁症机制的研究现状

Research status of mechanism of psilocybin in the treatment of treatment-resistant depression

难治性抑郁症是一种具有药物抵抗性的重度抑郁症亚型,目前尚缺乏有效且持久的治疗方法。赛洛西宾是裸盖菇的活性物质,是一种天然的5-羟色胺能致幻剂,能够激活5-羟色胺2A受体介导抗抑郁作用的多个方面。近年来赛洛西宾因在治疗难治性抑郁症或是其他精神类疾病方面发挥出突出显著的治疗作用而重新受到关注。本文通过总结国内外文献中赛洛西宾在神经可塑性、大脑神经连接网络、神经递质、免疫因子、微生物群-肠-脑轴和临床疗效等方面的研究,探索赛洛西宾对抗难治性抑郁症作用的可能机制,以期为临床应用该药物提供理论依据。

Refractory depression is a drug-resistant subtype of major depressive disorder for which there is a lack of effective and durable treatments.Seroxibine,the active substance in the mushroom Capsicum annuum,is a natural 5-hydroxytryptamine hallucinogen that activates the 5-hydroxytryptamine 2A receptor to mediate multiple aspects of antidepressant effects.In recent years,it has received renewed attention for its outstanding therapeutic effects in the treatment of refractory depression or other psychiatric disorders.Therefore,this paper summarizes the studies on neuroplasticity,brain neural connectivity network,neurotransmitters,immune factors,microbiota-gut-brain axis,and clinical efficacy of seloxipine in domestic and international literature,and explores the possible mechanisms of seloxipine's effect on refractory depression,with a view to providing theoretical basis for the clinical application of this drug.
