从用重组金丝雀痘病毒(ALVAC-gp 100)免疫的HLA-A*0201/Kb(A2/Kb)转基因小鼠中,分离出HLA-A*0201限制性CTL。在嵌合A2/Kb和野生型HLA-A*0201−分子的背景下,这些CTL强烈响应gp 100154 -162表位,并在体外有效裂解人HLA-A*0201+,gp 100+黑素瘤细胞。在A2/Kb转基因小鼠中分析了CTL在体内根除这些肿瘤的能力,所述转基因小鼠在眼前房中接受了致瘤剂量的人葡萄膜黑素瘤细胞。这种免疫豁免位点提供了将异种肿瘤移植到免疫活性A2/Kb转基因小鼠中的独特机会,否则它们将不会在宿主中生长。重要的是,全身(i. v.)A2/Kb转基因gp 100154 -162特异性CTL的施用导致眼内葡萄膜黑素瘤的快速消除,表明抗肿瘤CTL能够归巢到眼睛并发挥其杀肿瘤效应子功能。用流式细胞术分析含有HLA-A*0201-gp 100154 -162四聚体复合物的眼细胞悬液证实了过继转移的CTL的归巢。因此,眼睛的免疫豁免状态允许异种葡萄膜黑色素瘤细胞的生长,但不能保护这些肿瘤免受高效抗肿瘤CTL的过继免疫治疗。这些数据构成了人类葡萄膜黑色素瘤的免疫治疗可能是可行的第一个直接迹象。
HLA-A*0201-restricted CTL against human gp100 were isolated from HLA-A*0201/Kb (A2/Kb)-transgenic mice immunized with recombinant canarypox virus (ALVAC-gp100). These CTL strongly responded to the gp100154–162 epitope, in the context of both the chimeric A2/Kb and the wild-type HLA-A*0201− molecule, and efficiently lysed human HLA-A*0201+, gp100+ melanoma cells in vitro. The capacity of the CTL to eradicate these tumors in vivo was analyzed in A2/Kb-transgenic transgenic mice that had received a tumorigenic dose of human uveal melanoma cells in the anterior chamber of the eye. This immune-privileged site offered the unique opportunity to graft xenogeneic tumors into immunocompetent A2/Kb-transgenic mice, a host in which they otherwise would not grow. Importantly, systemic (i.v.) administration of the A2/Kb-transgenic gp100154–162-specific CTL resulted in rapid elimination of the intraocular uveal melanomas, indicating that anti-tumor CTL are capable of homing to the eye and exerting their tumoricidal effector function. Flow cytometry analysis of ocular cell suspensions with HLA-A*0201-gp100154–162 tetrameric complexes confirmed the homing of adoptively transferred CTL. Therefore, the immune-privileged state of the eye permitted the outgrowth of xenogeneic uveal melanoma cells, but did not protect these tumors against adoptive immunotherapy with highly potent anti-tumor CTL. These data constitute the first direct indication that immunotherapy of human uveal melanoma may be feasible.
