ORFV-PrCoA2/B7 encodes two HLA-B*07-restricted human immunodeficiency virus 1 (HIV-1)- and ovarian cancer (OvCa)-derived peptides and one HLA-A*02-restricted HIV-1 peptide in a minigene format (Table S1, Figure S1), and served as a control for the CD8+ T cell priming assay. Here, HLA-B is linked to ovarian cancer.
