However, how CD8\n            <jats:sup>+<\/jats:sup>\n            T cells adapt to chronic stimulation remains unclear. Here, we show that persistent antigen stimulation primes chromatin for regulation by the redox-sensing KEAP1-NRF2 pathway. Loss of KEAP1 in T cells impaired control of chronic viral infection.

NRF2 epigenetically derepressed BACH2 targets and opposed a stem-like program driven by BACH2. In exhausted T cells induced by tonic GD2 chimeric antigen receptor (CAR) signaling, the effects of KEAP1 deficiency were rescued by inhibiting proximal TCR signaling.
