Writing in Science, Al Habsi et al. show that spermidine boosts the efficacy of monoclonal antibodies targeting PD-L1 in aged tumor-bearing mice by enhancing fatty acid oxidation in CD8 T cells. These results open new therapeutic avenues to improve the effectiveness of anticancer immunotherapies in aged patients.
