Mitochondrial and lipid metabolism rewiring during HEV infection.

ABSTRACT: Hepatitis E virus (HEV), a leading cause of acute and chronic viral hepatitis, poses a persistent global health challenge. A deeper mechanistic understanding of virus-host interactions is critical for identifying therapeutic targets to mitigate HEV-associated disease. In this study, we employ a systems biology framework to comprehensively map metabolic and bioenergetic alterations induced by HEV genotypes 1 and 3 in HepG2/C3a-MAVS-KD cells, a robust model of HEV infection, enabling reliable assessment of virus- and host-driven cellular changes. Our analyses reveal extensive remodelling of host metabolism, including reprogramming of the tricarboxylic acid (TCA) cycle, mitochondrial oxidative phosphorylation (OXPHOS), fatty acid metabolism, and β-oxidation-pathways that collectively sustain
