细胞生物学细胞生物学

背景情况:

Vitiligo 是一种复杂的皮肤疾病,具有遗传和免疫成分.
最近的研究表明,白风明显没有影响的皮肤也会显示细胞异常.
这些亚临床变化对于了解疾病进展至关重要.

研究的目的:

审查白病患者的非损伤性皮肤中存在的细胞变化.
要突出黑色素细胞,角质素细胞和纤维细胞的功能和结构变化.
讨论这些变化对免疫反应和疾病发病的影响.

主要方法:

审查关于白风病源的现有科学文献.
在非损伤性皮肤样本中分析细胞和分子变化.
检查线粒体功能,氧化应激和免疫信号通路.

主要成果:

非损伤性黑色素细胞表现出线粒体功能障碍和氧化应激增加,影响它们的粘附和功能.
角质细胞和纤维细胞表现出结构和功能异常,阻碍了黑色素细胞的支持和分化.
这些细胞分泌有助于炎症的化学基因,导致免疫微环境的改变.

结论:

非损伤性白风皮肤的细胞异常很普遍,影响黑色素细胞,角质细胞和纤维细胞.
这些变化有助于免疫激活,尽管调节机制保持亚临床状态.

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
