概括
通过流动细胞计量测量酸结合性Ig-like lectin 1 (Siglec-1) 表达是检测干扰素 (IFN) 相关炎症的实用工具. 在儿科风湿病学中,Siglec-1提供了比ESR和CRP等传统炎症标志物更好的准确性.
科学领域:
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
- 流动细胞计量 (Flow Cytometry) 是一种流动细胞计.
背景情况:
- 传统的炎症标志物,如红细胞沉积率 (ESR) 和C反应蛋白 (CRP),往往不足以诊断与干扰素 (IFN) 相关的疾病.
- 已经提出了干扰素评分 (IS),测量IFN刺激的基因表达,但可能不适合常规临床使用.
- 通过流式细胞计测量可测量的酸结合性Ig样性莱克1 (Siglec-1) 表达,为评估IFN相关炎症提供了潜在的替代方案.
研究的目的:
- 评估Siglec-1表达的实用性作为干扰素 (IFN) 相关炎症的标记物在儿科风湿病学环境中.
- 将Siglec-1的诊断性能与干扰素评分 (IS) 和常规炎症标志物 (ESR,CRP) 进行比较.
- 根据炎症水平,确定测量Siglec-1 (阳性细胞百分比与平均光强度) 的最佳方法.
主要方法:
- 招募了98名受试者,包括患有免疫风湿学疾病,急性感染和骨科手术对照的患者.
- 在所有受试者中使用流细胞计测量测量Siglec-1表达.
- 记录的干扰素评分 (IS),ESR和CRP,如果可用于比较.
主要成果:
- 与IS相比,Siglec-1表达表现出很好的准确度 (86.0%),灵敏度 (85.7%) 和特异性 (72.7%).
- 在较低的IFN炎症水平下,Siglec-1-阳性细胞的百分比更具信息性,而在较高的水平上,平均光强度更好.
- 西格莱克-1表达与ESR或CRP没有相关性,即使这些标志物正常,也会升高;在急性感染中也观察到高的西格莱克-1.
结论:
- 通过流细胞计测量Siglec-1的测量是检测干扰素 (IFN) 相关炎症的实用和准确的工具.
- 即使标准炎症标志物 (ESR,CRP) 产生正常结果,Siglec-1也可以识别IFN相关的炎症.
- 这种测试在儿科风湿病学和可能涉及IFN失调的其他疾病中提供了有价值的诊断方法.

The JAK-STAT Signaling Pathway
8.8K
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...

Selectins

Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...
