概括
类风湿性关节炎 (RA) 患者表现出大脑连接的改变,与炎症和神经精神问题有关. 这些动态的功能连接性变化可以作为RA病理学的生物标志物.
科学领域:
- 神经成像是一种神经成像.
- 类风湿病学 类风湿病学
- 精神病学是一个精神病学.
背景情况:
- 类风湿性关节炎 (RA) 是一种全身性自身免疫性疾病,已知具有关节外表现,包括神经精神病症状.
- 在RA患者中观察到大脑的功能连接性改变,但动态变化不太了解.
研究的目的:
- 探索类风湿性关节炎 (RA) 患者的动态功能连接 (DFC) 改变.
- 在RA患者中调查DFC变化,神经精神症状 (认知功能,焦虑,抑郁) 和外周炎症标志物之间的相关性.
主要方法:
- 休息状态功能性MRI (fMRI) 用于分析30名RA患者和30名健康对照 (HCs) 的DFC,通过空间独立组件分析和滑动窗口方法.
- 斯皮尔曼相关性被用来评估DFC,蒙特利尔认知评估 (MoCA),医院焦虑和抑郁量表 (HAD),C反应蛋白 (CRP) 和红细胞沉积率 (ESR) 之间的关系.
- 进行了接收器操作特征 (ROC) 分析,以评估已识别的指标的诊断效果.
主要成果:
- 确定了三种不同的动态功能状态.
- 与HC相比,RA患者在感官处理网络 (连接感官运动网络与insula和轨道前皮层) 中表现出功能连接 (FC) 变异性的减少.
- 这些FC变异与MoCA,HAD,CRP和ESR有显著的相关性. CRP和ESR与MoCA呈现负相关性,与HAD呈现正相关性.
- ROC分析表明,MoCA,HAD和感官处理网络FC的变异性可以将RA患者与HC区分开来,并确定RA患者的ESR升高.
结论:
- 感官处理网络中的异常DFC模式与RA中的外周炎症和神经精神症状密切相关.
- 大脑功能网络的动态时间特征代表了潜在的神经成像生物标志物,以了解RA的病理机制.
- 这些发现强调了DFC分析在表征系统性炎症,大脑功能和RA的临床表现之间的复杂相互作用方面的实用性.

T Cell Types and Functions
1.0K
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
8.9K
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...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
