Persistent DNA damage and accumulation of senescent cells are associated with the progression of radiation-induced injury. Atopic dermatitis and RSI have similar inflammatory symptoms. The treatment of tacrolimus (TAC) in atopic dermatitis may be associated with premature cellular senescence. TAC can prevent the onset of cellular senescence by inactivating the p38 mitogen-activated protein kinase (p38 ​MAPK). The activation of p38 ​MAPK can induce the senescence-associated secretory phenotype (SASP) by enhancing the transcriptional activity of nuclear factor kappa-B (NF-κB), which ultimately leads to premature cellular senescence. FK506 binding protein 51 (FKBP51) exhibits resistance to ionizing radiation, but the mechanism of TAC regulation of ionizing radiation-induced premature senescence still needs further study.
