美国研究人员最近宣称,将对1例癌症患者进行新的基因疗法治疗,即将DNA直接注入体内。这例病人患有转移的恶性黑素瘤,将接受编码移植抗原HLA-B7的基因注射。美国密执安大学医学中心的Nabel说,目的是使患者的免疫系统能排斥注入肿瘤细胞的DNA,还可排斥基因上未改变的和改变的肿瘤细胞。 U.S. researchers recently announced that they will conduct a new gene therapy treatment on one cancer patient, that is, direct injection of DNA into the body. This patient has metastatic malignant melanoma and will be injected with the gene encoding the transplant antigen HLA-B7. Nabel, of the University of Michigan Medical Center, said that the goal is to make the patient’s immune system repel the DNA that invades the tumor cells and also to reject genetically unaltered and altered tumor cells.
