These results confirmed that both HPV-18 E781–95 (#21) and E789–103 (#23) epitopes were naturally processed in both HTB-34 and SNU-1160 cervical cancer cell lines and were to be useful as the HLA-A*02:01 and HLA-A*24:02 immunogenic epitopes within the HPV18 E7 protein. This evidence concerns the gene HLA-A and cervical carcinoma.
