Abstract
A radiolabeled probe specific for hepatitis B virus (HBV) nucleotide sequences was hybridized in situ to liver tissue from 3 patients with chronic hepatitis B. The HBV genome was detected not only in infected hepatocytes but also in bile duct epithelial cells, endothelial cells and smooth muscle cells. These findings extend the known host cell range for HBV, suggest new mechanisms of viral dissemination and illustrate the usefulness of in situ hybridization in the study of pathogenesis of HBV infection.
