概括

在全身性红斑狼 (SLE) 患者中,介素16 (IL16) 水平发生变化,淋巴细胞中的细胞内IL16减少,细胞外IL16增加,导致T细胞迁移和器官炎症. 阻断IL16显示了治疗潜力.

科学领域:

免疫学免疫学免疫学
类风湿病学类风湿病学

背景情况:

干白素16 (IL16) 失调与系统性红斑狼 (SLE) 病原发生有关.
在SLE中IL16的确切细胞起源和功能仍然不完全理解.

研究的目的:

为了研究IL16在SLE患者中的细胞来源和作用.
评估IL16水平与疾病活性和临床变量之间的相关性.
为了探索IL16阻断的治疗潜力.

主要方法:

40名SLE患者的循环IL16+免疫细胞的光谱流细胞测量分析.
测量血 (pIL16) 和尿液IL16 (uIL16) 的水平.
关于IL16对T细胞迁移和阻断的影响的体外研究.

主要成果:

活跃的SLE患者表现出IL16表达性免疫细胞的比例降低,特别是在Th1-样细胞和血质细胞中.
狼性炎 (LN) 患者在特定细胞子集中显著降低IL16表达,并增加uIL16,与疾病活性相关.
在体外,IL16促进了T细胞迁移,该迁移被IL16阻断部分抑制.

结论:

在SLE淋巴细胞,特别是LN中,细胞内IL16表达的减少与细胞外IL16的增加有关.
细胞外IL16通过驱动T细胞透,可能导致与SLE相关的器官炎症.
准IL16为SLE提供了一个潜在的治疗策略.

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...
