概括
大多数接受csDMARD治疗的活跃类风湿性关节炎患者的IL-6基因表达率高于瘤亡因子α (TNF-α). 年轻的年龄预测这些类风湿性关节炎患者的IL-6水平更高.
科学领域:
- 免疫学 免疫学 免疫学
- 类风湿病学 类风湿病学
- 分子生物学分子生物学
背景情况:
- 类风湿性关节炎 (RA) 是一种自身免疫性疾病,其特征是慢性炎症.
- 瘤坏死因子-α (TNF-α) 和互白素-6 (IL-6) 是关键的促炎细胞因子,涉及RA的发病.
- 传统的合成疾病修饰药物 (csDMARDs) 是对RA的标准治疗方法,但了解这些疗法患者的细胞因子表达是至关重要的.
研究的目的:
- 在接受csDMARD治疗的活跃RA患者中比较TNF-α和IL-6的基因表达水平.
- 确定影响TNF-α和IL-6基因表达的临床和实验室因素.
主要方法:
- 这是一项涉及108名接受csDMARD治疗的活跃RA患者的横截面研究.
- 临床评估包括详细的病史,体检和疾病活动评分28 (DAS28).
- 通过qRT-PCR分析了实验室标记物 (CRP,ESR,RF) 和基因表达水平 (TNF-α,IL-6).
主要成果:
- 在TNF-α和IL-6基因表达之间存在显著的正相关性 (p<0.001,r=0.788).
- 这两种细胞因子表达与年龄和DAS28 (p<0.001) 有正相关性.
- 在81.5%的患者中观察到较高的IL-6表达;与年轻的年龄,较短的疾病持续时间,较低的DAS28和较高的CRP/RF水平相关.
结论:
- 在接受csDMARDs的活跃RA患者中,介素-6 (IL-6) 基因表达通常高于瘤亡因子-α (TNF-α).
- 与TNF-α相比,年轻年龄是相对较高的IL-6基因表达的重要预测因素.
- 疾病活动 (DAS28),CRP和RF水平与差异性细胞因子基因表达模式有关.

T Cell Types and Functions
1.1K
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.

The JAK-STAT Signaling Pathway
9.0K
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...

NF-κB-dependent Signaling Pathway
7.5K
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.
