概括

骨关节炎 (OA) 化,特别是来自酸铁 (CPP) 晶体的化,与突液中炎症媒介的升高相关. 这表明CPP沉积和OA炎症之间存在联系.

科学领域:

生物化学生物化学
免疫学免疫学免疫学
整形外科整形外科整形外科

背景情况:

关节组织化在晚期骨关节炎 (OA) 中很常见.
化可能是由于基本酸 (BCP) 或酸盐 (CPP) 晶体沉积而产生的.
在OA中,CPP沉积越来越与炎症和细胞衰老有关.

研究的目的:

调查OA化和炎症调解剂之间的关联.
分析关于晶体类型 (BCP与CPP) 的突液和膜中的炎症媒介度.

主要方法:

从接受关节置换的OA患者收集的突流体.
使用多重测定 (Luminex®技术) 测量的细胞因子度.
放射学评估了化;拉曼光谱识别了水晶类型.

主要成果:

在OA患者的放射性化与突液细胞因子 (IL-10,IL-15,IL-1ra,GM-CSF),化学因子 (IL-8,MCP-1,MIP-1b) 和生长因子 (PDGF-AB/BB,VEGF) 的升高相关.
与BCP化患者相比,患有CPP化的患者显示IL-15,IL-1ra,IL-10,GM-CSF,PDGF-AB/BB和MIP-1b的度更高.

结论:

在OA突流体中增加的细胞因子概况与放射性化有关.
这些发现表明,CPP沉积与OA软骨中观察到的炎症概况之间存在潜在的联系.

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...
