Interaction between hepatitis delta virus-encoded proteins and hepatitis B virus envelope protein domains.
Hepatitis delta virus (HDV) packaging requires prenylation of the HDV large protein (p27), as well as a direct protein-protein interaction between HDV proteins and hepatitis B virus (HBV) envelope protein domains. To investigate this interaction, we have analysed the binding capacity of baculovirus-expressed delta p24 and p27 proteins to synthetic peptides specific for the HBV envelope. Althoug...
متن کاملThe middle hepatitis B virus envelope protein is not necessary for infectivity of hepatitis delta virus.
The hepatitis delta virus (HDV) envelope contains the large (L), middle (M), and small (S) surface proteins encoded by coinfecting hepatitis B virus. Although HDV-like particles can be assembled with only the S protein in the envelope, the L protein is essential for infectivity in vitro (C. Sureau, B. Guerra, and R. Lanford, J. Virol. 67:366-372, 1993). Here, we demonstrate that the M protein, ...
متن کاملRole of the large hepatitis B virus envelope protein in infectivity of the hepatitis delta virion.
The hepatitis delta virus (HDV) is coated with large (L), middle (M), and small (S) envelope proteins encoded by coinfecting hepatitis B virus (HBV). To study the role of the HBV envelope proteins in the assembly and infectivity of HDV, we produced three types of recombinant particles in Huh7 cells by transfection with HBV DNA and HDV cDNA: (i) particles with an envelope containing the S HBV en...
متن کاملEnvelope proteins derived from naturally integrated hepatitis B virus DNA support assembly and release of infectious hepatitis delta virus particles.
UNLABELLED A natural subviral agent of human hepatitis B virus (HBV), hepatitis delta virus (HDV), requires only the envelope proteins from HBV in order to maintain persistent infection. HBV surface antigens (HBsAgs) can be produced either by HBV replication or from integrated HBV DNA regardless of replication. The functional properties of the integrant-generated HBsAgs were examined using two ...
متن کاملHepatitis B and hepatitis delta virus infection in South America.
About 100,000 cases of acute hepatitis B virus (HBV) infection occur annually in South America. The overall prevalence of HBV infection in low risk populations ranges from 6.7% to 41%, while hepatitis B surface antigen (HBsAg) rates range from 0.4% to 13%. In high endemicity aboriginal or rural populations, perinatal transmission may play a major part in the spread of HBV. In urban populations,...
