IL-2-PE40 is a chimeric molecule in which IL-2 is attached to the amino end of modified Pseudomonas exotoxin molecule lacking cell recognition domain. This molecule was extremely toxic for Con A-stimulated spleen cells from mice. Moreover, IL-2-PE40 has suppressive effect against Ag-activated cells; it inhibits the generation of cytotoxic T lymphocyte activity in a MLC. IL-2-PE40 could be a useful agent in IL-2R targeting therapy including immunosuppressive therapy for allograft rejection or some autoimmune diseases.
白细胞介素-2-铜绿假单胞菌外毒素40(IL-2-PE40)是一种嵌合分子,其中白细胞介素-2连接到缺乏细胞识别域的修饰铜绿假单胞菌外毒素分子的氨基末端。该分子对来自小鼠的刀豆蛋白A刺激的脾细胞具有极高的毒性。此外,IL-2-PE40对抗原激活的细胞具有抑制作用;它在混合淋巴细胞培养中抑制细胞毒性T淋巴细胞活性的产生。IL-2-PE40可能是白细胞介素-2受体靶向治疗中的一种有用药物,包括用于同种异体移植排斥或某些自身免疫性疾病的免疫抑制治疗。
