RESUMEN
Ojbective To predicte the HLAⅠrestricted CTL epitopes and B cell antigen epitopes derived from tumor antigen SCCAg. Methods The linear B cell epitopes and conformational B cell epitopes of tumor antigen SCCAg were predicted by Ellipro program. In addition, the HLAⅠrestricted CTL epitopes of SCCAg were predicted by NetCTL, Prot-Param and so on. Results B cell epitopes analysis revealed that SCCAg had 10 potential linear B cell epitopes and 5 conformational B cell epitopes; Combined with peptide HLAⅠbinding, proteasomal C - terminal cleavage and TAP transport efficiency, the NetCTL predicts that multiple HLAⅠrestricted CTL epitopes were present in the tumor antigen SCCAg. Conclusion The B cell epitopes and HLAⅠrestricted CTL epitopes can be predicted by multiple methods, which may lay the foundation for the further research on immunotherapy for targeting SCCAg.
