Aging is associated with increased atherosclerosis risk and a changing immune landscape. In this study, the authors examined T cell changes in atherosclerotic plaques in mice with age and report an accumulation of clonally expanded effector and memory CD8+ T cells, including Gzmk+CD8+ T cells, which have cytotoxic transcriptomic signatures.
