We review here the seminal findings of Desdin-Mico et al. showing that T cells with dysfunctional mitochondria induce multimorbity and premature senescence, due to mitochondrial transcription factor A (TFAM). They add further weight to the idea that targeting immunometabolism could be beneficial in combating the detrimental effects of age-related disease.
