As the main components of the cell membrane and lipid droplets, lipids with various structures play an important role in a wide range of biological processes, such as signal transduction, transport, and the separation of biological macromolecules with different biochemical properties. With the rapid development of lipidomics in recent years, scientists have gradually separated the study of lipidomics from metabolomics. Creative Proteomics is an international contract research organization (CRO). We continue to expand our services and improve our existing resources to help our customers accelerate their research and support their projects. Since lipids play critical roles in stages of virus replication, we have established a robust platform with validated lipid coverage and stable liquid chromatography-mass spectrometry (LC-MS) system for lipidomic analysis of viral infections.

Generally, there are five phases of viral replication within the host cells, including attachment, entry/penetration, replication, maturation/assembly, and release. During the stages, viruses take advantage of a repertoire of host cell lipids to complete their life cycle. Lipids can be used as receptors or co-factors for virus entry, components or regulators of viral replication complex, and signaling factors for the distribution of viral protein in cells and the transport, assembly, and release of viral particles. It is reported that both reduced and oversupplied lipogenesis enzymes can disrupt efficient virus replication, suggesting that the intact lipid landscape induced by viral infection is necessary for optimal viral replication. Lipid profiles of host cells infected with many viruses have yet to be fully characterized.
Lipidomics is the investigation of a comprehensive map of all lipids (the lipidome) within a cell or organism. In recent years, the application of lipidomics has benefited greatly from the advances in mass spectrometry (MS) methodologies. The MS-based method enables the identification of hundreds and thousands of lipids in biological matrices. Lipidomics studies have shown that viral infection can significantly change the lipid group of the host, thus elucidating the potential pathogenic mechanism.
Applications of lipidomics analysis
Based on liquid mass spectrometry (LC-MS) technology, our experimental process of lipidomics research mainly includes sample collection, lipid extraction, LC-MS/MS detection, and data analysis. Our unbiased lipidomics approach is reliable and fast in identifying significant differences in the host lipid profiles during virus infection.
