摘要: 【摘要】 衰老是年龄相关的机体退行性变,皮肤改变是其最直观的表现之一。细胞老化源于细胞周期的持久性阻滞,它既是衰老的重要标志,也是衰老发生发展的重要机制。随着皮肤的衰老,在表皮和真皮中老化细胞均逐渐累积并进一步加剧衰老,而清除老化细胞则可使皮肤年轻化。细胞老化参与衰老进程可能与激活DNA损伤反应通路、上调阻滞细胞周期的调节蛋白、分泌衰老相关表型增多等机制有关。干预细胞老化有望在将来成为临床抗衰老的新思路和新手段。

Abstract: 【Abstract】 Aging is age-related degeneration of the whole body, and skin aging is one of the most visualized changes in aging. Cellular senescence is a stress response to stable cell cycle arrest, and it is both the hallmark of aging and the important mechanism of the occurrence and development of aging. With the development of skin aging, senescent cells gradually accumulate in both the epidermis and dermis, and further exacerbate aging. Thus, when these senescent cells are eliminated, the aging skin seems to be rejuvenated. Cellular senescence is involved in the process of skin aging, which may be related to activation of DNA damage response pathway, up-regulation of regulatory proteins blocking cell cycle, and increase of senescence-associated secretory phenotypes. Cellular senescence is expected to be a novel target for preventing skin aging in the future.

Key words: Skin aging, Cell aging, Senescence?associated secretory phenotype
