 For keratinocytes, the proportion of cells that have elimination by help apoptosis, with an increase in UVR dose can reach to achieve 45%, but with a further increase in the dose of UVR (due to the shutdown of the mechanism of apoptosis), destruction of damaged cells by help necrosis and the part of cells that eliminated by apoptosis begins to decrease (non-monotonous dose dependence of UV-induced apoptosis) [4, 11].In the dose range of UVR from “lethal” to “super-lethal”, “pro-inflammatory” apoptosis can be manifested, which was experimentally discovered in 2003 [5].This may be the result of partial damage to the apoptosis mechanism by UV radiation [1].
