CD8A and neoplasm: In this study, when FVB mouse (MHC haplotype: H-2q) bone marrow-derived DCs (BMDCs) were co-cultured with dying H-2b tumor cells expressing ovalbumin (OVA), the H-2q BMDCs acquired the OVA peptide-H-2Kb complexes from tumor cells and subsequently activated CD8+ T cells from OT-I mice specific for OVA residues 257–264 on H-2Kb.
