概括
炎症驱动的血管生成会影响精神分裂症和双相情感障碍的血脑屏障. 中脑血管新生变化,特别是精神分裂症中的SERPINE1,表明神经炎症的作用.
科学领域:
- 神经科学是一个神经科学.
- 病理学 病理学 病理学
- 分子生物学分子生物学
背景情况:
- 炎症增加了血脑屏障 (BBB) 的透性和巨细胞的传播.
- 之前的研究已经确定了BBB分子改变中脑神经炎症在精神分裂症和双相情感障碍.
- 在这些条件下,中脑的血管生成变化尚未报告.
研究的目的:
- 调查精神分裂症和双相情感障碍患者中脑中血管发生变化的分子证据.
- 为了比较患者组和对照组之间的血管新生变化,以及精神分裂症内的炎症水平.
主要方法:
- 从精神分裂症 (n=35),双相情感障碍 (n=35) 和对照 (n=33) 的死后腹腔中脑组织的病例控制研究.
- 血管生成相关分子mRNA (RT-PCR) 和蛋白质 (多重免疫试验) 的量化.
- 免疫组织化学被用来确定这些分子的解剖分布.
主要成果:
- 在双相情感障碍中,高炎症子组显示血管蛋白-2和SERPINE1mRNA增加,但血管蛋白-1,血管蛋白-2和TEK受体蛋白减少.
- 在精神分裂症中,高炎症亚组显示 SERPINE1 mRNA 和蛋白质显著增加.
- 在高炎症精神分裂症中,VEGFA mRNA增加,但与所有低炎症子组相比,没有达到统计学意义.
结论:
- 血管新生信号通路与精神分裂症和双相情感障碍中中脑炎症相关的BBB变化有关.
- 高炎症精神分裂症中SERPINE1的升高和高炎症双相情感障碍中抑制的血管蛋白信号传递表明有不同的作用.
- 这些发现强调了血管新生在这些神经炎症疾病的病理生理学的参与.

Biological Causes of Schizophrenia
46
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
