HLA-A and neoplasm: As shown in Figure 7, CTLs stimulated by ERBB2, BIRC5 and CD99 peptide-pulsed DCs could recognize these three peptides and produce IFN-γ when the peptides were naturally presented by glioblastoma cell lines and primary glioblastoma cells in the context of HLA-A*0201, and could kill ERBB2-, BIRC5- and CD99-positive tumor cells in the LDH cytotoxicity assay.
