Figure 1 Hepatitis C virus viral life cycle.
Hepatitis C virus (HCV) entry into human hepatocytes is a complex, multi-step process that takes place at the basolateral region of polarized hepatocytes. It begins when the viral particle binds surface glycosaminoglycans (GAGs) and the low-density lipoprotein receptor (LDLR) via apolipoprotein E. This is followed by a complex series of interactions mediated by cellular factors including scavenger receptor class B type I (SR-BI), the tetraspanin CD81, claudin-1 (CLDN1), occludin (OCLN), the Niemann-Pick C1-like 1 (NPC1L1) receptor, as well as receptor tyrosine kinases (RTKs) that promote CD81-CLDN1 association and membrane fusion. The HCV particle is then internalized into the hepatocyte by clathrin-mediated endocytosis.
