IFI16 and cytomegalovirus infection: Finally, lipids containing medium-chain fatty acid substituents with up to 2 double bonds (e.g., PC32:0, PC32:1, and PC34:0), lysoglycerophosphocholines (lysoPCs), and some diacylglycerolphosphoserines (PSs) were significantly downregulated in IFI16 KO versus WT HFFs following HCMV infection.
