概括

研究人员在患有全身性红斑狼 (SLE) 的患者中发现了较高水平的CD4+CD40+T细胞 (Th40细胞). Th40细胞水平与SLE疾病活性相关,表明它们作为SLE严重程度和治疗反应的生物标志物的潜力.

科学领域:

免疫学免疫学免疫学
类风湿病学类风湿病学
细胞生物学细胞生物学

背景情况:

系统性红斑狼 (SLE) 是一种复杂的自身免疫性疾病,其特征是免疫系统失调.
特定的T细胞子集,如CD4+CD40+T细胞 (Th40细胞) 在SLE病变发生中的作用需要进一步阐明.

研究的目的:

调查SLE.中国患者Th40细胞的患病率和特征.
探索Th40细胞水平与SLE疾病活动,器官参与和治疗疗效之间的关联.

主要方法:

使用流细胞计量,量化SLE患者和健康对照者的外周血液中的Th40细胞百分比.
血清细胞因子水平 (IL-2,IL-4,IL-6,IL-10,IFN-γ,TNF-α) 和SLE疾病活性 (SLEDAI-2000) 被评估.
分析了Th40细胞百分比,临床参数和治疗结果之间的相关性.

主要成果:

与健康个体相比,SLE患者的Th40细胞百分比显著更高 (19.37%与4.52%,P<0.001).
Th40细胞的百分比与SLEDAI-2000分数正相关 (P = 0.001),与补充C3水平负相关 (P = 0.007).
在狼血清炎和狼肺炎患者中观察到Th40细胞的升高,治疗后水平显著下降 (P = 0.005).

结论:

在SLE患者中,Th40细胞显著增加,与疾病活动和严重程度有关.
Th40细胞水平可以作为SLE疾病活动和治疗反应的有价值的预测生物标志物.
需要进行进一步的研究,以探索Th40细胞参与SLE的确切机制.

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...

T Cell Activation and Clonal Selection

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...
