| Research Abstract |
We demonstrated that HCV altered sphingolipids metabolism, performing the analysis, using MS spectrometer, of the sphingolipids content in uninfected humanized chimeric mice, HCV infected chimeric mice, and HCV infected chimeric mice treated with the inhibitor of sphingolipids biosynthesis. Furthermore, specific sphingomyelin molecular species contributed to HCV replication, and these sphigomyelin molecular species activated the polymerase of HCV.
