OBJECTIVE To determine whether liver-derived hepatitis C RNA-containing particles express the E1E2 discontinuous antigenic determinant defined by unique monoclonal antibody (mAb) D32.10 which recognizes three highly conserved segments in E1 (aa297-306) and E2 (aa480-494 and aa613-621) envelope glycoproteins. METHODS Human hepatocytes were isolated from HCV-infected cirrhotic explanted livers....
hepatitis c virus (hcv) is an important agent causing chronic liver infection, which often leads to liver cirrhosis and lethal hepatocellular carcinoma (hcc). at present, there is no effective hcv vaccine for prevention of hepatic disease and the standard treatment is neither economical nor fully effective in all the patients. however, vaccination based on structural and nonstructural proteins ...
BACKGROUND Hepatitis C virus (HCV) is a main public health problem causing chronic liver infection and subsequently liver cirrhosis and lethal hepatocellular carcinoma (HCC). Vaccination based on HCV capsid proteins has attracted a special interest for prevention of viral infections.

The hepatitis C virus (HCV) envelope glycoproteins E1 and E2 form a non-covalently linked heterodimer on the viral surface that mediates viral entry. E1, E2 and the heterodimer complex E1E2 are candidate vaccine antigens, but are technically challenging to study because of difficulties in producing natively folded proteins by standard protein expression and purification methods. To better compr...
Retroviral Gag and Env glycoproteins (GPs) are expressed from distinct cellular areas and need to encounter to interact and assemble infectious particles. Retroviral particles may also incorporate GPs derived from other enveloped viruses via active or passive mechanisms, a process known as "pseudotyping." To further understand the mechanisms of pseudotyping, we have investigated the capacity of...
A recombinant strain HCV1 (hepatitis C virus [HCV] genotype 1a) gpE1/gpE2 (E1E2) vaccine candidate was previously shown by our group to protect chimpanzees and generate broad cross-neutralizing antibodies in animals and humans. In addition, recent independent studies have highlighted the importance of conserved neutralizing epitopes in HCV vaccine development that map to antigenic clusters in E...
UNLABELLED The hepatitis C virus (HCV) envelope glycoprotein E1E2 complex is a candidate vaccine antigen. Previous immunization studies of E1E2 have yielded various results on its ability to induce virus-neutralizing antibodies in animal models and humans. The murine model has become a vital tool for HCV research owing to the development of humanized mice susceptible to HCV infection. In this s...
