HIGH-AFFINITY AND SOLUBLE PDL-1 MOLECULE
(FR)
MOLÉCULE DE PDL-1 SOLUBLE À FORTE AFFINITÉ
(ZH)
高亲和力的可溶性PDL-1分子
Abstract:
(EN)
Provided in the present invention is a PDL-1 molecule. The affinity of the PDL-1 molecule to the PD-1 molecule is at least two times the affinity of the wild-type PDL-1 molecule to the PD-1 molecule. Meanwhile, the PDL-1 molecule of the present invention can effectively improve the killing efficiency of lymphocytes. In addition, the present invention also provides nucleic acids encoding the PDL-1 molecule of the present invention, and a complex of the PDL-1 molecules of the present invention. The PDL-1 molecule of the present invention may be used alone or in combination with other molecules.
(FR)
La présente invention concerne une molécule de PDL-1. L'affinité de la molécule de PDL-1 pour la molécule de PD-1 est au moins deux fois supérieure à l'affinité de la molécule de PDL-1 de type sauvage pour la molécule de PD-1. La molécule de PDL-1 selon la présente invention peut effectivement augmenter l'efficacité de destruction des lymphocytes. La présente invention concerne également des acides nucléiques codant la molécule de PDL-1 selon la présente invention, et un complexe des molécules de PDL-1 selon la présente invention. La molécule de PDL-1 selon la présente invention peut être utilisée seule ou en association avec d'autres molécules.
(ZH)
本发明提供了一种PDL-1分子,所述PDL-1分子与PD-1分子的亲和力是野生型PDL-1分子与PD-1分子的亲和力的至少2倍。同时,本发明的PDL-1分子能够有效地提高淋巴细胞的杀伤能力。另外,本发明还提供了编码本发明PDL-1分子的核酸,以及本发明PDL-1分子的复合物。本发明的PDL-1分子可以单独使用,也可与其他分子联用。
