Increased glycolytic metabolism recently emerged as an essential process driving host defense against Brucella, but little is known about how this process is regulated during infection. We have identified a critical role for nuclear factor kappa B (NF-κB) transcription factor regulation in glycolytic switching during Brucella infection for the first time. Chromatin immunoprecipitation with next-generation sequencing for NF-κB and DNA Pull-Down revealed two novel NF-κB-binding sites in the enhancer region of the Nitric oxide (NO)production-response regulator gene glucose-6-phosphate dehydrogenase (G6PD), which is important for the switch to glycolysis during a Brucella infection. These findings demonstrate that Brucella drives metabolic reprogramming by inhibiting host oxidative phosphorylation (OXPHOS) and enhancing its glycolysis via the NF-κB-G6PD-NO-pathway. These studies provide a theoretical basis for investigating drugs or vaccines to control Brucella colonization and induction of undulant by manipulating host metabolic patterns.
