概括
从类风湿性关节炎 (RA) 患者的单细胞中微RNA (miRNA) 表达与健康对照没有区别. 然而,特定的miRNAs (miR-194-5p,miR-9-5p) 显示出基于普得尼松使用的水平变化,与NFKB1和TRAF6基因表达相关.
科学领域:
- 免疫学 免疫学 免疫学

背景情况:
- 类风湿性关节炎 (RA) 是一种由慢性炎症为特征的自身免疫性疾病.
- NFKB1和TRAF6是参与炎症途径的关键基因,可能由microRNAs (miRNAs) 调节.
- 了解miRNA参与RA病变可能会揭示新的治疗点.
研究的目的:
- 研究RA患者单细胞中特定miRNAs (miR-194-5p,miR-124-3p,miR-9-5p,miR-340-5p) 和它们的基因 (NFKB1,TRAF6) 的表达.
- 评估miRNA/基因表达和RA患者的细胞因子水平之间的相关性.
- 评估RA治疗,特别是普得尼松对miRNA和基因表达的影响.
主要方法:

T Cell Types and Functions
967
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.

NF-κB-dependent Signaling Pathway
7.4K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
124
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...
