背景情况:

骨关节炎 (OA) 是一种普遍存在的退行性关节疾病.
衍生外体 (GDE) 具有抗炎性质.
对于OA,GDE的治疗潜力仍然未被探索.

研究的目的:

为了研究GDE对骨关节炎的影响.
评估GDE对软骨矩阵组件和炎症通路的影响.
评估GDE在OA的体内小鼠模型中的有效性.

主要方法:

提取和GDE的特征.
在体外研究中,使用用IL-1β和GDEs治疗的红细胞,通过西方涂抹和RNA-seq.分析.
在体内OA小鼠模型 (ACLT/DMM) 与关节内GDE注射,通过行为和本病理学分析进行评估.

主要成果:

GDEs抵消了IL-1β诱导的原II和亚格格兰的下调,以及细胞中MMP3和MMP9的上调.
GDE 抑制了 MAPK 路径酸化 (ERK,JNK,P38).
在体内,GDE改善了与OA相关的行为缺陷,并改善了没有毒性的关节破坏.

结论:

在体外和体内,GDEs都显示出对骨关节炎进展的保护作用.
GDEs可能作为一种新的疾病修饰性治疗剂用于骨关节炎.
对OA管理的GDE进行进一步的研究是有必要的.

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...
