概括
重度抑郁症与增加的17A (IL-17A) 和粒细胞巨细胞殖民地刺激因子 (GM-CSF) 水平有关. 这表明,联素-23/Th17通路在抑郁症中过度活跃,可能是治疗的目标.
科学领域:
- 神经免疫学 神经免疫学
- 精神病学是一个精神病学.
- 免疫学 免疫学 免疫学
背景情况:
- 互白素-23/T-助手17 (Th17) 免疫通路与各种炎症状况有关.
- 这种途径的失调越来越被认为是主要抑郁症 (MDD) 病理生理学的潜在因素.
- 需要对MDD中的IL-23/Th17轴进行系统评估.
研究的目的:
- 系统地评估IL-23/Th17轴与严重抑郁之间的关联.
- 在MDD患者和健康对照者之间比较Th17细胞及其细胞因子 (IL-17A,IL-22,GM-CSF) 的血/血清水平.
- 在MDD中调查Th1,Th2和Th9细胞计数及其相关细胞因子.
主要方法:
- 在四个数据库 (EMBASE,科学网,PubMed,PsycINFO) 中进行系统的文献搜索.
- 针对免疫措施的标准化平均差异 (SMD) 的随机效应元分析.
- 使用纽卡斯尔-太华尺度进行偏差风险评估.
主要成果:
- 对36项研究的元分析显示,与对照人群相比,抑郁症患者的IL-17A (SMD=0.80) 和GM-CSF (SMD=0.54) 升高.
- 在抑郁症患者中观察到更高Th17细胞计数 (SMD=0.44) 的趋势.
- 发现IL-5 (Th2-关联细胞因子) 的升高,但Th1和Th2细胞数量没有显著差异.
结论:
- 患有严重抑郁症的患者表现出IL-23/Th17免疫轴的外周过度激活.
- 这种免疫失调,特别是涉及IL-17A和GM-CSF,可能会导致抑郁症.
- IL-23/Th17途径代表了潜在的可修改的抑郁症治疗点.

T Cell Types and Functions
990
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

The JAK-STAT Signaling Pathway
8.8K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

Depression: Overview
231
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...

Stress and Mental Health
96
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.
