概括
具有自杀念头或行为的人显示白细胞和中性粒细胞数量升高,表明炎症. 免疫细胞比率,如中性粒细胞对淋巴细胞的比率,可以作为抑郁症以外的自杀倾向的潜在生物标志物.
科学领域:
- 神经科学是一个神经科学.
- 免疫学 免疫学 免疫学
- 精神病学是一个精神病学.
背景情况:
- 之前的研究将免疫-炎症通路与重大抑郁发作 (MDE) 病理生理学联系起来.
- 目前尚不清楚自杀念头 (SI) 或自杀行为 (SB) 的免疫变化是否与MDE不同.
- 这项研究研究了SI/SB患者的外周免疫细胞概况.
研究的目的:
- 系统地审查和元分析SI/SB患者的外周免疫细胞概况.
- 为了比较SI/SB个体与健康对照组或MDE患者之间的免疫细胞概况.
- 识别与SI/SB相关的潜在免疫标记物.
主要方法:
- 在 MEDLINE,Embase 和 PsycINFO 中进行系统的文献搜索.
- 使用随机效应模型来计算标准化平均差异 (SMD) 的元分析.
- 包括30项研究,包括19项研究的元分析 (139项比较).
主要成果:
- 在SI/SB患者中,白细胞 (WBC) 和中性粒细胞数量升高,暗示着炎症.
- 在SI/SB组中增加了中性粒细胞与淋巴细胞的比率 (NLR) (SMD = 0.695).
- 即使在比较具有和没有SI/SB的MDE个体时,也观察到免疫变化.
结论:
- 周边免疫细胞种群的广泛变化表明SI/SB中的免疫激活或功能障碍.
- 与自杀倾向相关的免疫功能障碍不仅仅是由抑郁症状解释的.
- NLR,MLR和PLR比率显示出作为理解和监测SI/SB的生物标志物的潜力.

Regulation of Hematopoietic Stem Cells
3.2K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Borderline Personality Disorder is a complex and multifaceted mental health condition characterized by pervasive instability in interpersonal relationships, self-image, emotions, and impulse control. This instability manifests in extreme emotional reactions, fear of abandonment, and self-destructive behaviors. The disorder significantly impacts daily functioning, often leading to distress in both personal and professional domains.
