Subsequently, Cafri et al. performed in vitro stimulation of memory T cells isolated from two patients with KRAS-mutated solid tumors (one with endometrial cancer, one with rectal cancer) and identified CD8+ T cells specific for an HLA-A*11:01-restricted epitope from KRAS G12V and CD4+ T cells specific for an HLA-DRB1*08:01 restricted epitope from KRAS G12D (156). The gene discussed is KRAS; the disease is rectal cancer.
