摘要
Hepatitis C virus (HCV) antigen expression was examined by immunohistochemical staining in liver tissue taken at biopsy from 8 anti-HCV positive patients. Frozen liver sections were stained by indirect immunofluorescence for capsid, E2/NS1, NS3, NS4 and NS5 using polyclonal antibodies raised to synthetic peptides from these regions. The antigens E2 and NS3 were localised in scattered hepatocytes and also in cells within and around areas of inflammation. A weaker signal was observed for NS4 and NS5 and no signal was seen for capsid antigen. No staining was seen in liver tissue from 9 individuals, including 3 hepatitis B virus-positive and 2 hepatitis delta virus/positive patients, who were negative for serological markers of HCV. The specificity of the staining reaction was also confirmed by the lack of staining in HCV-positive liver samples, after the antisera was pre-adsorbed against the specific peptide. Collectively, the data suggests that HCV may not only be hepatotropic but also lymphotropic, and this may be an important factor in the pathogenesis of HCV infection. © 1993 The Japanese Society of Gastroenterology.
