据《新科学家》报道,貌似人类抗体的小鼠抗体也许会成为同肺癌、白血病作战的新一代武士,目前正在美国用于临床试验。科学工作者利用遗传工程技术对小鼠抗体进行伪装,使它们表面的氨基酸同人体抗体表面的氨基酸一个样,这就使患者的免疫系统不会视之为“异物”而攻击之。这样的抗体还可以用来运载蓖麻蛋白这类烈性毒物,用作攻击肿瘤细胞 According to “New Scientist,” mouse antibodies that look like human antibodies may become a new generation of warriors fighting lung cancer and leukemia. They are currently being used in clinical trials in the United States. Scientists use genetic engineering techniques to camouflage mouse antibodies so that their surface amino acids are the same as the amino acids on the surface of human antibodies. This prevents the patient’s immune system from attacking them as foreign objects. Such antibodies can also be used to carry such potent poisons as ricin to attack tumor cells.
