Dengue virus and lipid metabolism: unravelling the interplay for future therapeutic approaches

In recent years, Dengue virus (DENV) has continued to pose significant health risks in tropical and subtropical areas worldwide, raising health alerts worldwide. It can cause hyperviremia in humans and can even lead to fatal clinical diseases. The life cycle of DENV is intricately linked to cellular lipids, and the virus selectively utilizes relevant enzymes involved in lipid metabolism to modulate the existing metabolic system in host cells during entry, replication, assembly, and other stages, thereby creating an environment conducive to its complete replication cycle. At present, there is a lack of effective and specific anti-DENV treatment measures. This review summarizes the recently identified lipid metabolism molecules and metabolic related diseases that affect DENV infection, explores the dependence of DENV on lipid metabolism and provides potential targets for the treatment of dengue fever (DF).
