Memory T cells are particularly reliant on fatty acid oxidation as a source of energy. Here the authors show this reliance is controlled by AMPK sensing of glucose deprivation that triggers SENP1-Sirt3 signalling, driving fatty acid oxidation and memory differentiation in T cells via deacetylation of YME1L1 to induce mitochondrial fusion.
