Hepatitis B virus (HBV) infection drives macrophages toward an M2-polarized phenotype, contributing to immune evasion and viral persistence. However, the underlying mechanisms involving post-translational modifications and metabolic reprogramming remain poorly understood. This study integrates multi-omics and functional analyses to characterize lysine acetylation and lipid metabolic alterations in HBV-induced macrophages. In vitro and in vivo models confirmed HBV-promoted M2 polarization, marked by elevated CD206/CD163 expression and anti-inflammatory cytokine secretion. Acetylomic profiling identified 450 modified proteins and 432 quantifiable sites, with significant upregulation of peptides associated with chromatin remodeling and metabolic regulation. Lipidomic analysis revealed extensive reprogramming, including downregulation of phosphatidylcholines, phosphatidylinositols, and oxidized lipids, and upregulation of specific sphingolipids and triacylglycerols. Functional enrichment linked acetylated proteins to lipid metabolic processes and oxidative stress response. These findings suggest that HBV remodels macrophage acetylation and lipid metabolism, which may contribute to the development of an immunosuppressive microenvironment, providing new insights into potential therapeutic strategies targeting acetylation or lipid pathways in chronic HBV infection. SIGNIFICANCE: This study systematically characterizes lysine acetylation profiles and lipid metabolic reprogramming in HBV-induced macrophages using multi-omics and functional assays. It identifies HBV-driven acetylation changes in 450 proteins, which target chromatin remodeling and metabolic regulation, as well as distinct lipid alterations including reduced lipid storage and modified glycerophospholipids and sphingolipids. The study reveals that crosstalk between acetylation and lipid metabolism fosters an immunosuppressive microenvironment that supports HBV persistence. These findings fill critical gaps in understanding the mechanisms of HBV-induced macrophage polarization and provide novel therapeutic targets for chronic HBV infection.
