The present invention is directed toward the delivery of a toxic protein to pathogenic cells, particularly cancer cells. In preferred embodiments, the toxic protein is a ribonuclease that has been modified to make it toxic to target cells and that can be conjugated to a target cell-specific delivery vector, such as an antibody, for delivery to pathogenic cells.
本发明的目的是向致病细胞,特别是癌细胞输送毒性蛋白质。在优选的实施方案中,毒性蛋白是一种
核糖核酸酶,经过修饰使其对靶细胞具有毒性,并可与靶细胞特异性递送载体(如
抗体)连接,以递送至致病细胞。
