Boosting T cell immunity against cytomegalovirus : a potential strategy combating human aging and age-related diseases

ItemZeitschriftenaufsatzOpen Access

Abstract

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 II (HLA-II) 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.
