Abstrakt: We studied the effects of age and suntan on the expression of necroptosis signaling molecules (RIPK1, RIPK3, and MLKL kinases) and first TNF receptor (TNFR1) in isolated skin cells from women undergoing facelift surgery. In women above 50 years, the expression of the TNFR1, kinases RIPK1, RIPK3, and MLKL, the phosphorylated forms of these kinases was significantly (p<0.05) increased in comparison with the corresponding parameters in women under 30 years. The expression of all necroptosis proteins and TNFR1 in women with suntan was significantly (p<0.05) higher than in those without tan. Cells from the surgical material were incubated with TNFα to determine the level of induced necroptosis. In women aged >50 years and women with suntan, the expression of phosphorylated forms of kinases was significantly increased, which attested to necroptosis activation. This study allowed identifying the targets on skin cells for prevention of necrosis and inflammation after facelift surgery.
