Research Abstract

The hepatitis C virus (HCV) is affecting a host's lipid metabolism, and there isa possibility of raising the efficiency of infection and multiplicationby HCV protein. We showed that especially HCV protein controlled the hepatic triglyceride lipase (HTGL) which metabolizes very-low density lipoprotein (VLDL). This phenomenon was similarly approved in a host's liver. In conclusion,the substance, which could increase theHTGLexpression,could be anew therapeutictarget forHCV.
