Furthermore, this patient is positive for human leukocyte antigen (HLA)-A2, allowing us to characterize CD8+ T cell immune response against well-characterized HLA-A2-restricted GAA-epitopes, such as EphA2 883–891 [18] and IL-13Rα 2 345–353 [19], both of which were expressed in this patient's tumor. This evidence concerns the gene CD8A and neoplasm.
