    We investigated the efficacy of peptide and peptide-pulsed dendritic cell-based vaccines in a murine model of experimental MHC class I-deficient tumours (TC-1/A9), expressing E6/E7 oncogenes derived from HPV16. Peptide vaccine based on the “short” peptide E749-57 harbouring the CTL epitope and co-administered to the C57BL/6 mice with CpG oligodeoxynucleotide as adjuvant effective against MHC class I-positive but not –deficient tumours, while the “longer” peptide E744-62 (harbouring CTL and Th epitopes)-based vaccines were effective against MHC class I-deficient tumours. Further, we investigated the efficacy of dendritic cells pulsed with either E749-57 or E744-62 peptides. Treatment with dendritic cells pulsed with a “short” peptide resulted in the tumour growth inhibition, albeit weaker as compared to the immunisation with the longer peptide-containing DC. Our data demonstrate that cell-based vaccines can be designed to elicit immunity against MHC class I-deficient tumours.
