Popis: SEG and SEI are primordial S. aureus superantigens (SAgs) notably unaccompanied by human neutralizing antibodies that have hampered the use of classic SAgs as cancer therapeutics. Here we show SEG/SEI presented from a HLA-DQ8αβ (HLA-DQA*0301 and HLA-DQB*0302) tg platform outperform C57BL/6 mice in achieving long term survival in vaccinated and established Lewis lung carcinoma (LLC) and B16-F10 melanoma. Vaccination of DQ8 tg mice with LLC or B16-F10 melanoma followed by SEG/SEI immunization and subsequent tumor challenge resulted in 100% and 83% survival for >150 days respectively, compared to a median survival of 14 days in unvaccinated DQ8 tg controls (p
