core antigen

One effort has involved use of the hepatitis B core antigen.

HBcAg (core antigen) is a hepatitis B viral protein.

Antibody to hepatitis B core antigen (anti-HBc) appears 2 weeks after HBsAg and persists for life.

Low prevalence of ongoing hepatitis B viremia in HIV-positive individuals with isolated antibody to hepatitis B core antigen.

The icosahedral core particle is made of 180 or 240 copies of core protein, alternatively known as hepatitis B core antigen, or HBcAg.

Hepatitis B virus DNA in persons with isolated antibody to hepatitis B core antigen who subsequently received hepatitis B vaccine.

Prevalence of isolated antibody to hepatitis B core antigen in an area endemic for hepatitis B virus infection: implications in hepatitis B vaccination programs.

The icosahedral nucleocapsid within, is composed of the virus core antigen (DHBcAg) and surrounds the DNA genome and viral polymerase.

Response to hepatitis B vaccine in HIV-1-positive subjects who test positive for isolated antibody to hepatitis B core antigen: implications for hepatitis B vaccine strategies.

Hepatitis B core antibody (HBcAb) is an antibody to the hepatitis B core antigen that appears about 1 month after an active HBV infection.

During this 'window' in which the host remains infected but is successfully clearing the virus, IgM antibodies to the hepatitis B core antigen (anti-HBc IgM) may be the only serological evidence of disease.

The risk of reactivation varies depending on the serological profile; those with detectable HBsAg in their blood are at the greatest risk, but those with only antibodies to the core antigen are also at risk.

In particular, there was a striking morphological appearance in five infected livers in which the hepatocytes became progressively enlarged and distorted as they accumulated huge amounts of hepatitis B surface and core antigens (HBsAg, HBcAg).

Blood banks test for this antibody when screening donated blood for hepatitis B. Hepatitis B core antibody IgM (HBcAbIgM) is another antibody to the hepatitis B core antigen.

Testing laboratories and occupational health departments should find the data concerning the proportion of non-responders who have antibodies to core antigen useful in estimating the number of hepatitis B carriers likely to be revealed with use of the protocol suggested in the joint working party's paper.

If the host is able to clear the infection, eventually the HBsAg will become undetectable and will be followed by IgG antibodies to the hepatitis B surface antigen and core antigen (anti-HBs and anti HBc IgG).
