Abstract/OtherAbstract:
The localization of hepatitis B antigen (HB Ag) and the nature of the virus-like particles in hepatocytes of patients with HB antigenemia are controversial. In many reports, numerous virus-like particles have been demonstrated in hepatocytic nuclei; the few reported in the cytoplasm are insufficient in number to explain the intense cytoplasmic fluorescence after staining with fluoresceinated antibody to HB Ag (HB Ab). We found numerous tubular and circular structures, measuring 20 to 30 nm in diameter, in the cisternae of the excess smooth endoplasmic reticulum (ER) of varying numbers of hepatocytes in 13 of 16 HB Ag carriers and in 4 of 9 patients with HB Ag-positive chronic hepatitis corresponding to cytoplasmic HB Ag-specific fluorescence. Direct immunoelectronmicroscopy using peroxidase-labeled HB Ab revealed that the intracisternal bodies and the surrounding membranes contain HB antigenic determinants. These bodies are an ultrastructural correlate of cytoplasmic HB Ag. It is suggested that they are virally coded coat material rather than the mature hepatitis B virus or its core.
