Pharmacological stabilization of hypoxia-inducible factor 1-α dampens the interferon response and promotes glycolysis in Aicardi-Goutières syndrome
Aicardi-Goutières syndrome (AGS) is a genetic type I interferon (IFN)-mediated disease characterized by neurological involvement with onset in utero or in childhood. Here, we analyze peripheral blood samples from patients bearing AGS-causing mutations in ADAR1, RNASEH2B or SAMHD1 using single-cell transcriptomics and targeted metabolomics. Using machine-learning approaches and differential gene expression analysis, we identified a loss of transcription factor hypoxia induced factor 1 α (HIF-1α) expression and activity associated with features of a metabolic switch favoring oxidative phosphorylation and glutathione metabolism over glycolysis in monocytes and dendritic cells. Evidences of mitochondrial stress and accumulation of cytosolic double-stranded DNA and RNA were also found. The energy metabolic switch was confirmed at the metabolic level in primary peripheral blood mononuclear cells of AGS patients. Chemical stabilization of HIF-1α using a synthetic drug in in vitro cellular models of AGS, reversed the energy metabolic switch towards glycolysis, attenuated mitochondrial stress, and markedly reduced the IFN response and IP-10 production. We therefore propose that an energy metabolic switch contributes to chronic inflammation in AGS and that targeting this pathway might represent a potential therapeutic approach.
