Abstract:
Objective To explore the mechanism of CTL dysfunction in HCV infected person, to provide a theoretical basis for further understanding the pathogenesis of hepatitis C and the development of HCV vaccines. Methods HCV nucleopolypeptides were selected and synthesized with the method of solid phase synthesis. BALB/c mice were immunized subcutaneously with HCV nucleopolypeptides, and CTL activity of mice was detected by LDH releasing test. Results CTL of mice could be inhibited by HCV nucleopolypeptides residues 39-74, 67-76, 71-80 and enhanced by HCV nucleopolypeptides residues 5 23,63 72,131 140. Conclusion The function of CTL can be suppressed and intensified by different HCV nucleopolypeptides.
