摘要:

抑郁症是一种复杂的异质性疾病,社会压力是抑郁症最关键的因素之一。脑源性神经营养因子(brain-derived neurotrophic factorBDNF)表达的改变通常被用作社会压力对大脑和系统生理影响的指标,在抑郁症的病理生理中起着关键作用。一些涉及应激处理的大脑区域已被广泛研究,包括腹侧被盖区、伏隔核、海马、前额叶皮层和杏仁核,并且在抑郁症患者和啮齿动物抑郁症模型中已经报道了这些大脑区域的功能。虽然脑源性神经营养因子在中枢神经系统情绪加工中的作用已被广泛研究,但关于脑源性神经营养因子信号的区域特异性仍缺乏全面的总结,这对于更好地理解抑郁症和社会压力有重要作用。文章综述了近年来关于不同脑区的脑源性神经营养因子作为慢性应激背景下抑郁行为的关键介质的作用。综上所述,作者总结了近年来的研究,以阐明脑源性神经营养因子表达与社会应激的关系。许多用于治疗抑郁症的药物会改变脑源性神经营养因子的表达和信号转导。暴露于压力和抑郁会降低海马和前额叶皮质中脑源性神经营养因子的表达,上调腹侧被盖区和伏隔核中的脑源性神经营养因子,但杏仁核中脑源性神经营养因子的表达在研究中的变化不一。因此,脑源性神经营养因子的变化可能对不同脑区有不同的影响,该因子可能是调节大脑各区域压力相关过程的生物指标。

Abstract: Brain-derived neurotrophic factor is a key factor in stress adaptation and avoidance of a social stress behavioral response. Recent studies have shown that brain-derived neurotrophic factor expression in stressed mice is brain region–specific, particularly involving the corticolimbic system, including the ventral tegmental area, nucleus accumbens, prefrontal cortex, amygdala, and hippocampus. Determining how brain-derived neurotrophic factor participates in stress processing in different brain regions will deepen our understanding of social stress psychopathology. In this review, we discuss the expression and regulation of brain-derived neurotrophic factor in stress-sensitive brain regions closely related to the pathophysiology of depression. We focused on associated molecular pathways and neural circuits, with special attention to the brain-derived neurotrophic factor–tropomyosin receptor kinase B signaling pathway and the ventral tegmental area–nucleus accumbens dopamine circuit. We determined that stress-induced alterations in brain-derived neurotrophic factor levels are likely related to the nature, severity, and duration of stress, especially in the above-mentioned brain regions of the corticolimbic system. Therefore, BDNF might be a biological indicator regulating stress-related processes in various brain regions.
