概括

系统性硬化症患者表现出互白蛋白 (IL-21) 和IL-22.2的水平发生变化. 升高的IL-21可能表明这种罕见的自身免疫性疾病的疾病严重程度和肺部并发症.

科学领域:

免疫学免疫学免疫学
类风湿病学类风湿病学
遗传学遗传学是一个

背景情况:

系统性硬化症 (SSc) 是一种罕见的,致命的自身免疫性疾病,具有多种不同的临床表现.
识别特定的生物标志物对于改善患者护理至关重要,特别是在罕见疾病中.
了解SSc中的细胞因子概况对于阐明疾病机制至关重要.

研究的目的:

在突尼斯系统性硬化症患者中识别潜在的生物标志物.
为了研究SSc.中IL-21和IL-22之间的表达.
为了将细胞因子表达与临床表现相关联,特别是肺部并发症.

主要方法:

定量实时聚合酶链反应 (qRT-PCR) 用于分析IL-21和IL-22的基因表达.
流细胞测量以评估Th17细胞群.
分析RNA测序数据以进一步验证.
对IL-17A和RORγt基因表达的qRT-PCR分析.

主要成果:

与健康对照组相比,在SSc患者中观察到上调的IL-21和下调的IL-22表达.
增加的IL-21水平与SSc患者的肺部并发症显著相关.
在SSc患者和对照人群之间没有发现Th17细胞计数的显著差异.
基因表达分析支持观察到的细胞因子失调.

结论:

在突尼斯SSc患者中存在涉及IL-21和IL-22的明显细胞因子失调.
IL-21可能作为一种潜在的生物标志物,用于SSc.的疾病严重程度和肺部参与.
Th17细胞可能不是SSc.中观察到的细胞因子失衡的主要驱动因素.

T Cell Types and Functions

T Cell Types and Functions

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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

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...
