Abstract
Apoptosis, or programmed cell death, is an essential physiological process that controls cell numbers during physiological processes, and eliminates abnormal cells that can potentially harm an organism. This review summarizes our current state of knowledge of apoptosis induction in skin by UV radiation. A review of the literature was undertaken focusing on cell death in the skin secondary to UV radiation. It is evident that a number of apoptotic pathways, both intrinsic and extrinsic, are induced following exposure to damaging UV radiation. Although our understanding of the apoptotic processes is gradually increasing, many important aspects remain obscure. These include interconnections between pathways, wavelength-specific differences and cell type differences. L’apoptose, ou mort cellulaire programmée, est un processus physiologique essentiel au contrôle du nombre de cellules durant les processus physiologiques et à l’élimination des cellules anormales qui représentent un danger potentiel pour l’organisme. Le présent article fait le point sur nos connaissances actuelles quant à l’induction de l’apoptose au niveau de la peau au moyen des rayons UV. Un examen des publications scientifiques traitant de la mort cellulaire à la suite de l’exposition de la peau aux rayons UV a été fait. Il est évident qu’un nombre de voies apoptotiques, intrinsèques et extrinsèques, sont déclenchées à la suite de l’exposition à des rayons UV néfastes. Bien que notre compréhension des processus apoptotiques augmente graduellement, nombreux restent les aspects importants qui demeurent obscurs, notamment les interconnexions entre les voies, les différences propres aux ondes et aux types de cellules.Keywords
