概括

系统性硬化症 (SSc) 皮肤表现出"网状化"的表型,这是由于正常WNT/β-catenin激活的丧失造成的. 恢复这种途径可能有助于修复纤维化疾病中的皮肤结构.

科学领域:

皮肤病学和分子生物学
结合组织疾病结合组织疾病
皮肤生理学皮肤生理学

背景情况:

身体成年人的皮肤完整性依赖于不太了解的机制.
系统性硬化症 (SSc) 的特征是皮肤纤维化和结构变化.
了解SSc皮肤变化的分子基础对于治疗开发至关重要.

研究的目的:

量化比较SSc患者与对照者的皮肤解剖学.
调查驱动SSc相关皮肤变化的潜在分子机制.
探索WNT/β-catenin信号传递在SSc皮肤中的作用.

主要方法:

皮肤形态的组织学评估在SSc患者,对照组和过度缩痕患者.
使用RNAscope和免疫光学对WNT/β-catenin激活的空间分析.
基因本体学和基因组丰富分析以确定纤维细胞亚群和标记基因.

主要成果:

与对照组相比,SSc皮肤表现出减少的乳头数量,面积和高度.
在SSc.中观察到, papillary/reticular标记基因向网状表达特征的转变.
在SSc皮肤中失去正常的空间WNT/β-catenin激活偏振,在皮肤中增加了AXIN2和β-catenin阳性纤维细胞.

结论:

这是一个很棒的节目,这是一个很棒的节目.

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...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
