 UVB-induced apoptosis

UV-induced apoptosis 
UV-induced apoptosis is an adequate (physiological) reaction of a cell damaged by UV radiation (UVR) in a sufficiently large (lethal) dose and it prevents the disordered destruction of UV damaged cells by help necrosis.Cell elimination by apoptosis occurs when UV-induced cell damage which cannot be repaired by the intracellular repair system exceeds at it certain limit (lethal damage).
