MLKL, a New Actor of UVB-Induced Apoptosis in Human Diploid Dermal Fibroblasts

Investigators evaluated the implication of receptor-interacting serine/threonine-protein kinase 3 (RIPK3) and mixed lineage kinase domain-like (MLKL) in ultraviolet radiation (UV) B-induced cell death in human diploid dermal fibroblasts, and reported that RIPK3 and MLKL played opposite roles in UVB-induced cell death, in a necroptosis independent pathway.
