来自治疗耐药精神分裂症 (TRS) 患者的细胞外囊泡 (EV) 显示了新陈代谢的改变,增加了乳酸. 通过二乙酸盐 (DCA) 抑制乳酸生产,在小鼠中逆转了类似精神分裂症的缺陷,这表明了新的治疗点.
科学领域:
- 神经科学是一个神经科学.
- 生物化学 生物化学
- 遗传学 是一个遗传学.
背景情况:
- 精神分裂症影响着数百万人,其中约30%的人发展出治疗耐药性.
- 了解耐治疗精神分裂症 (TRS) 病理生理学对于新疗法至关重要.
研究的目的:
- 研究血衍生细胞外囊泡 (EVs) 在TRS病理生理学中的作用.
- 确定TRS.的分子机制和潜在的治疗点.
主要方法:
- 来自TRS患者,非TRS患者和健康对照的EV的比较蛋白质组分析.
- 在小鼠体内行为研究和体外细胞培养实验.
- 使用二乙酸盐 (DCA) 的药理干预.
主要成果:
- 在小鼠中,TRS-EV诱导了类似精神分裂症的行为和神经元/星细胞异常.
- 蛋白质组分析揭示了TRS-EVs的代谢转变,抗氧化剂减少和糖分酶增加.
- 在TRS患者中,血乳酸的增加和PRDX2的减少与临床严重程度相关.
结论:
- 电动车中的代谢失调在TRS中起着关键作用.
- 通过DCA进行乳酸调制显示出作为TRS.治疗策略的前景.
