Heterogeneity of hepatitis delta antigen

Virology, 1990
Hepatitis delta antigen (HDAg) is the only known protein encoded by the hepatitis delta virus (HDV). Two HDAg species of different sizes have been detected in the sera and livers of the infected humans, chimpanzees, and woodchucks, even though only one RNA species was previously identified in most of the HDV strains.

Hepatitis delta antigen. Antigenic structure and humoral immune response.

The Journal of Immunology, 1989
Abstract Hepatitis delta virus (HDV) is a small RNA virus that is dependent on helper functions provided by hepatitis B virus. The hepatitis delta Ag (HDAg) is the only protein known to be made from the viral genome, from an ORF with a coding capacity of 214 amino acids. The immunogenic epitopes of HDAg and the immune response to it were

Hepatitis delta virus: protein composition of delta antigen and its hepatitis B virus-derived envelope

Journal of Virology, 1986
Hepatitis delta virus (HDV)-associated particles were purified from the serum of an experimentally infected chimpanzee by size chromatography and by density centrifugation. Hepatitis delta antigen (HDAg) was detected after mild detergent treatment at a column elution volume corresponding to 36-nm particles and banded at a density of 1.25 g/ml.

Hepatitis Delta Antigen

2007
Hepatitis delta antigen (HDAg) was first detected in the nucleus of the hepatocytes of some patients infected with hepatitis B virus (HBV).68 The presence of HDAg was frequently associated with severe hepatitis. This antigen was initially thought to be a previously unrecognized HBV-encoded antigen, but later was found to be associated with a novel ...

[Delta-antigen in hepatitis B].

Schweizerische medizinische Wochenschrift, 1982
Among 571 liver biopsies delta-Ag was found in 10 of 365 HBsAg positive patients (9 with CAH, 1 with CPH). Delta-Ag was demonstrated in nuclei and cytoplasm of liver cells in both cryostat and paraffin sections. Follow-up studies revealed persistence of delta-Ag for as long as 6 years and temporary appearance or loss of Dane particle-associated ...

Immune response to synthetic peptides of hepatitis delta antigen

Journal of Clinical Microbiology, 1993
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.

Acute delta hepatitis without hepatitis B surface antigen detectable in the blood

Journal of Infection, 1992
The case is described of a 42-year-old man suffering from acute delta hepatitis without hepatitis B surface antigen (HBsAg) being detectable in his blood. Tests on the patient's blood were negative for anti-HBcIgM and HBeAg but positive for anti-HBs, anti-HBe, HDAg and anti-DIgM.
