(FR) ANTICORPS BISPÉCIFIQUE À CHAÎNE UNIQUE, VIRUS ONCOLYTIQUE RECOMBINANT CHARGÉ D'ANTICORPS ET COMBINAISON DE VIRUS
(ZH) 双特异性单链抗体、负载抗体的重组溶瘤病毒及病毒组合
Abstract
(EN) The present invention provides a bispecific single-chain antibody BiTEs-PD-L1 capable of simultaneously binding to CD3 and PD-L1 on the surface of a tumor cell, an antibody-loaded recombinant oncolytic virus, and a virus combination. When BiTEs-PD-L1 enters a human body and binds to T cells, the T cells can be effectively activated, and the T cells are guided to kill tumor cells.
(FR) La présente invention concerne un anticorps bispécifique à chaîne unique BiTEs-PD-L1 pouvant se lier simultanément à CD3 et PD-L1 sur la surface d'une cellule tumorale, un virus oncolytique recombinant chargé d'anticorps, et une combinaison de virus. Lorsque BiTEs-PD-L1 entre dans un corps humain et se lie à des lymphocytes T, les lymphocytes T peuvent être activés de manière efficace, et les lymphocytes T sont guidés pour détruire des cellules tumorales.
(ZH) 本发明提供了一种能够同时结合CD3和肿瘤细胞表面PD-L1的双特异性单链抗体BiTEs-PD-L1、负载抗体的重组溶瘤病毒及病毒组合,当BiTEs-PD-L1进入体内与T细胞结合后,可以有效激活T细胞,并引导T细胞对肿瘤细胞进行杀伤。
