概括

在系统性硬化症 (SSc),纤维性自身免疫性疾病中发现了降低Interleukin-41 (IL-41) 的水平. 这种IL-41的减少可能会促进纤维细胞激活,从而导致SSc的病原性.

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:

系统性硬化症 (SSc) 是一种自身免疫性疾病,其特点是血管问题,炎症和纤维化.
纤维细胞激活到肌纤维细胞是SSc的核心,受到细胞因子的影响.
介素-41 (IL-41) 是一种具有免疫调节作用的细胞因子,越来越多地被认为超出了其阿迪波金起源.

研究的目的:

研究IL-41在全身性硬化症中的作用.
量化循环IL-41水平及其在SSc皮肤活检中的表达.
探索IL-41,纤维细胞激活和SSc.中相关信号通路之间的关系.

主要方法:

在SSc患者和对照人群中测量循环IL-41水平.
在SSc患者的皮肤活检中评估IL-41表达.
在SSc皮肤活检中量化哺乳动物目标拉巴胺素 (mTOR) 水平.

主要成果:

在患有扩散性SSc.的患者中,观察到IL-41循环水平显著降低.
在SSc患者的皮肤中,IL-41的表达也减少了.
在SSc皮肤中检测到mTOR的升高水平,这是IL-41的潜在下游标.

结论:

在全身性硬化症中,IL-41水平降低,这表明它可能在疾病中起作用.
减少IL-41可能会导致纤维细胞激活和SSc.中的纤维化.
提议IL-41作为一种潜在的抗纤维细胞因子,其减少可促进SSc中的纤维细胞激活.

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...

Receptor Downregulation in MVBs

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

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...
