概括

在类风湿性关节炎 (RA) 的小鼠模型中,介素-35 (IL-35) 治疗减少了关节损伤和炎症. 通过准骨质细胞形成,IL-35还抑制了骨质侵蚀,这表明它对RA的治疗潜力.

科学领域:

免疫学免疫学免疫学
类风湿病学类风湿病学
骨质免疫学骨质免疫学

背景情况:

类风湿性关节炎 (RA) 是一种慢性自身免疫性疾病,其特征是结膜炎,骨质侵蚀和关节损伤.
之前的研究表明,IN-35 (IL-35) 参与了RA的发病和骨质损失.

研究的目的:

在原诱导性关节炎 (CIA) 鼠标模型中评估IL-35的治疗疗效.
研究IL-35的抗关节炎机制,重点关注骨质细胞形成和炎症途径.

主要方法:

在DBA/1J小鼠中,CIA被诱导,随后每周注射IL-35.
临床关节炎,组织病理学和3D微型CT被用于体内评估.
在体外研究中使用了老鼠前骨细胞细胞系 (RAW264.7) 接受IL-35治疗,并通过JAK/STAT1通路阻塞进行评估.

主要成果:

在CIA小鼠中,IL-35治疗显著降低了突炎和骨损伤.
IL-35在体外减弱了炎症性细胞因子的产生和骨质结晶发生的标志物.
抑制JAK/STAT1通路进一步降低了IL-35治疗细胞中的骨质细胞形成标志物.

结论:

IL-35显示出抗骨质细胞形成的作用,缓解了RA中的骨损伤.
在小鼠中,IL-35有效地减轻了原诱导的关节炎.
IL-35在类风湿性关节炎治疗中具有潜在的治疗标.

T Cell Types and Functions

T Cell Types and Functions

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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

The JAK-STAT Signaling Pathway

The JAK-STAT Signaling Pathway

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...
