Abstract

T-cell memory linked to energy metabolism CD8 T cells play a crucial role in immunity to infection and cancer. The predictable pattern of a CD8 T-cell response to infection is well established, but the underlying cellular mechanisms regulating the transition to memory remain undefined. Here, Pearce et al. show that metabolic conversion to catabolic pathways of energy generation is key to CD8 T-cell memory development in vivo. CD8 T cells switch from glucose metabolism to fatty acid metabolism as they differentiate into a 'memory' cell that can 'remember' past infections. The process is regulated by the tumour necrosis factor receptor-associated factor protein TRAF6.
