概括

在男性和女性中,炎症对多巴胺神经元的影响不同. 互乐金-6会损害女性神经元,而男性神经元则通过MIAT产生补偿作用,而巴里西提尼布可以逆转这种作用.

科学领域:

神经科学是一个神经科学.
细胞生物学细胞生物学
精神病学是一个精神病学.

背景情况:

炎症增加与抑郁症的发病有关.
炎症可以通过减少多巴胺 (DA) 释放和腹状条纹体激活来导致动机缺陷.
炎症诱导的DA功能障碍的机制尚未完全理解.

研究的目的:

为了研究介质素-6 (IL-6) 在体外对人类诱导多能干细胞 (iPSC) 衍生的DAergic神经元的影响,来自两性.
探索长非编码RNA (lncRNA) MIAT在对IL-6的性别特异性反应中的作用.
为了确定与炎症相关的抑郁症的潜在治疗点.

主要方法:

在实验室中研究了来自健康男性和女性的人类iPSC衍生的DAergic神经元.
管理IL-6并分析了DA释放,神经元发射和突触囊泡 (SV) 运输.
进行了转录基因分析和基因淘汰 (MIAT).
测试了Janus激酶 (JAK) 抑制剂巴里丁的作用.

主要成果:

在女性DA神经元中,IL-6减少了DA释放,发射和SV运输/对接.
男性的DA神经元显示了SV速度/密度和突触前终端密度的补偿性增加.
这种IncRNAMIAT调解了性别差异;它在男性中被淘汰导致IL-6缺陷.
巴里西替尼在女性DA神经元中逆转了IL-6抑制作用.

结论:

IL-6不同影响男性和女性DA神经元,突出显著的性别差异在对炎症的反应.
在这些性别特异性反应中,IncRNA MIAT在中介起着至关重要的作用.
抑制JAK (例如,巴里西提尼布) 可能为抑郁症中与炎症相关的DA功能障碍提供治疗策略.

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
