PLOS ONE:免疫相关抑郁症中的抑郁症生物标志物

2018-12-01 海北 MedSci原创

最近,研究人员进行了一项探究,目的是确定以前未被认识的生物途径和生物标志物,可能会扩大抑郁症的炎症假说。

最近,研究人员进行了一项探究,目的是确定以前未被认识的生物途径和生物标志物,可能会扩大抑郁症的炎症假说。

研究人员使用Absolute IDQ p180试剂盒进行广泛代谢组学研究,分析来自31名慢性丙型肝炎患者的血浆样本,这些患者部分患有免疫相关抑郁症。该方法是一种直接流动注射和液相色谱的靶向代谢组学方法,用于测量酰基肉碱,氨基酸,生物胺,甘油磷脂,鞘脂和糖。

测量结果显示,与非抑郁性HCV患者相比,抑郁性HCV患者中支链氨基酸异亮氨酸的平均浓度显着降低 [抑郁组:中位数51.35(43.4-60.2μmol/ L);非抑郁组中位数62.10(38.4-81.7μmol/ L); U = -2.958; p = 0.002]。所有其他氨基酸,酰基肉碱,生物胺,甘油磷脂,鞘脂,糖,肝酶和甲状腺水平均无统计学差异。

因此,该研究的结果表明,支链氨基酸异亮氨酸可能在免疫相关的重度抑郁症的病理生理学中发挥作用,这扩展了关于抑郁症炎症假说的现有知识。
