Abstract:
Objective To explore the distribution and clinical significance of hepatitis B core antigen( HBcAg) in the hepatocytes of chronic hepatitis B virus infected patients. Methods Paraffin sections were made from 41 liver biopsy samples obtained from chronic hepatitis B virus infected patients. The immuno-fluorescence confocal technique was utilized to analyze the expression level and localization of HBcAg in hepatocytes. The data were analyzed by using Kruskal Wallis test and chisquare test. Results HBcAg expression were detected in 36 (87. 8%) patients, among whom 23 cases had moderate abnormal liver function, 10 with mild abnormal liver function and 3 with normal liver function. Among the cases with moderate abnormal liver function, 6 cases showed the simple membrane-type HBcAg expression, 17 cases showed mixed cytosolic-type and membrane-type HBcAg expression without the nuclear-type expression. Twelve cases with mild abnormal liver function only showed simple cytosolic-type HBcAg expression without membrane-type or nuclear-type expression. In the three patients with normal liver function, HBcAg was expressed in cytoplasm and nuclear but not on membrane. The correlation between HBcAg expression pattern and liver function was statistically significant (χ2 =10. 60, P<0.01). Conclusion HBcAg expression is directly correlated with liver injury in chronic hepatitis B virus infected patients, which indicates that membrane expressed HBcAg is the target antigen during the immuno-attack of liver.
