Abstract:T cells often encounter oxidative phosphorylation (OXPHOS) insufficiency upon activation, due to increased demands for ATP and NAD+ to fuel anabolic reactions. To explore how T cells overcome this insufficiency, we indirectly restricted OXPHOS by limiting mitochondrial ATP transfer to the cytosol using a T-cell-specific ADP/ATP translocase-2 knockout (Ant2-/-) mouse. Surprisingly, these naive T cells displayed heightened responsiveness to activation, increased proliferation, elevated IFNγ production and cytoto… Show more
