Unraveling virus-host interactions: Current advances in viral lipidomics.

Viruses significantly alter host lipid metabolism to facilitate their replication, assembly, and immune evasion. Lipidomics, a mass spectrometry-driven field, enables the comprehensive profiling of virus-induced lipid remodeling and provides crucial insights into host-pathogen interactions. This review provides a comprehensive overview of cutting-edge lipidomic research in viral infections, focusing on studies published from January 2023 onwards. Emphasis is placed on recent advancements in understanding key respiratory viruses (e.g., SARS-CoV-2), bloodborne pathogens (HIV, HCV), and emerging viral threats such as West Nile or the Dengue viruses. We examine the latest analytical platforms, annotation techniques, and biological findings, highlighting how specific alterations in glycerophospholipid, sphingolipid, and sterol pathways reveal novel diagnostic and therapeutic opportunities. While challenges in standardization, isomer annotation, and clinical translation persist, emerging MS technologies and computational strategies promise to overcome these limitations. Integrating lipidomics with systems biology approaches will be crucial for advancing precision virology and developing next-generation antiviral therapies.
