Structural and Antigenic Definition of Hepatitis C Virus E2 Glycoprotein Epitopes Targeted by Monoclonal Antibodies

Table 1

Schematic representation of the regions targeted by anti-HCV/E2 mAbs. Involved domains (DI, DII and DIII as well as the stem region) of HCV/E2 have been evidenced. In particular, DI has been described to be a discontinuous region containing the CD81 binding site; DII is predicted to possess the fusion peptide and DIII has been recently described to contain antigenic neutralization epitopes and to be involved in heterodimerization with E1.
