T cell differentiation into distinct functional effector and inhibitory subsets is regulated in part by the cytokine environment present at the time of antigen recognition. Here, we show that hypoxia-inducible factor 1 (HIF-1), a key metabolic sensor, regulates the balance between T regulatory (Treg) and TH17 differentiation. HIF-1α enhances TH17 development through direct transcriptional activation of RORvt, and via tertiary complex formation with RORvt and p300 recruitment to the IL17 promoter, thereby regulating TH17 signature genes. Concurrently, HIF-1α attenuates Treg development by binding Foxp3 and targeting it for proteasomal degradation. Importantly this regulation occurs under both normoxic and hypoxic conditions. Mice with HIF-1α deficient T cells are resistant to induction of TH17-dependent experimental autoimmune encephalitis associated with diminished TH17 and increased Treg cells. These findings highlight the importance of metabolic cues in T cell fate determination and suggest that metabolic modulation could ameliorate certain T cell-based immune pathologies.
