Immune-checkpoint blockade protects aged mice from infection

Abstract

A study demonstrates the efficacy of immune-checkpoint blockade in prolonging survival and boosting CD8+ T cell function in aged mice after pathogen exposure. These findings highlight how aging-related immune changes may lead to augmented CD8+ T cell responses to checkpoint blockade, which results in improved protection from infection. The findings also highlight the importance of understanding immune aging in future efforts to target immunotherapies to older adults.
