Abstract

Referido a receptores de union al antigeno mejorada que comprende un dominio transmembranario de anclaje y un dominio extracelular, en donde el dominio extracelular comprende una porcion de union al antigeno que comprende (i) un dominio variable de la cadena pesada (VH) que comprende una region determinante de la complementariedad de la cadena pesada (HCDR) 1 de SEQ ID NO:1, una HCDR 2 de SEQ ID NO:2 o SEQ ID NO:40, y una HCDR 3 de SEQ ID NO:3, y (ii) un dominio variable de la cadena liviana (VL) que comprende una region determinante de la complementariedad de la cadena liviana (LCDR) 1 de SEQ ID NO:4, una LCDR 2 de SEQ ID NO:5 y una LCDR 3 de SEQ ID NO:6. Tambien se refiere a un linfocito T transducido capaz de expresar el receptor de union al antigeno, un polinucleotido aislado que codifica el receptor de union al antigeno, un vector de expresion, y uso en el tratamiento del cancer.
