Immune response to synthetic peptides of hepatitis delta antigen.
Hepatitis delta antigen (HDAg) is the only viral protein known to be expressed during hepatitis delta virus (HDV) infection. Detection of antibody to HDAg (anti-HD) is the usual method for diagnosis of HDV infection since viremia lasts only a few weeks. In an effort to identify the major epitopes recognized by humans during natural infection, four oligopeptides including residues 2 to 17 (SP1),...
متن کاملConstruction and Eukaryotic Expression of Recombinant Large Hepatitis Delta Antigen
Background: Hepatitis delta virus (HDV) is a subviral human pathogen that exploits host RNA editing activity to produce two essential forms of the sole viral protein, hepatitis delta antigen (HDAg). Editing at the amber/W site of HDV antigenomic RNA leads to the production of the large form (L-HDAg), which is required for RNA packaging. Methods: In this study, PCR-based site-directed mutagen...

do not know whether it is due to the effects of toxic compounds or whether it is a genetic association. Whether dietary manipulation will affect the development of obstructive cardiomyopathy remains to be seen; if it does, diagnosis would need to be made early in life. Whatever the aetiology of the cardiomyopathy, the association with tyrosinaemia suggests that caution should be expressed in co...
متن کاملThe factors influencing the immune response to hepatitis B vaccine and persistence of the protection.
Hepatitis B virus (HBV) infection and its sequelae which include cirrhosis and hepatocellular carcinoma is a major public health problem throught the world.The WHO strategy for effective control of HBV infection is vaccination with the surface antigen of virus(HBsAg).The results obtained from a large number of studies demonstrated that the vaccine induces a protective antibody resonse (anti-HB...
متن کاملRelating structure to function in the hepatitis delta virus antigen.
Hepatitis delta virus expresses two forms of a single protein, the small (delta Ag-S) and large (delta Ag-L) antigens, which are identical except for an additional 19 residues present at the C terminus of delta Ag-L. While delta Ag-S is required to promote genome replication, delta Ag-L potently inhibits this process and also facilitates packaging of the viral genome by envelope proteins of the...
