摘要
In a recent publication in Cell,Hasegawa and colleagues reveal that cytotoxic CD4-positive cytotoxic T lymphocytes(CD4+CTLs)eliminate senescent fibroblasts with a surface expression of the immunologically important human leukocyte antigen class Il(HLA-)and the human cytomegalovirus glycoprotein B(HCMV-gB).1 This implies that a virome-immune cell interaction controls the fate of human skin cells that are linked to the aging process and associated diseases.
