Abstract

La presente invención se refiere a anticuerpos que se unen a antígenos en células diana y que dirigen restos efectores a dichas células, y a métodos de uso de los mismos. Reivindicación 1: Un conjunto de anticuerpos que comprende: i) un primer anticuerpo que comprende: a) un resto de unión a antígeno, en donde el resto de unión a antígeno se une a un antígeno diana; b) un polipéptido que comprende o consiste en un dominio variable de cadena pesada de anticuerpo (VH) de un sitio de unión a antígeno para un resto efector; y c) un dominio Fc que comprende dos subunidades, en donde el polipéptido de (b) se fusiona por su N-terminal al C-terminal del resto de unión a antígeno de (a) y por su C-terminal al N-terminal de una de las subunidades del dominio Fc de (c); y en donde el primer anticuerpo no comprende un dominio VL de un sitio de unión a antígeno para el resto efector; y ii) un segundo anticuerpo que comprende: d) un resto de unión a antígeno, en donde el resto de unión a antígeno se une a un antígeno diana; e) un polipéptido que comprende o consiste en un dominio variable de cadena ligera de anticuerpo (VL) de un sitio de unión a antígeno para el resto efector; y f) un dominio Fc que comprende dos subunidades, en donde el polipéptido de (e) se fusiona por su N-terminal con el C-terminal del resto de unión a antígeno de (d) y por su C-terminal al N-terminal de una de las subunidades del dominio Fc de (f); y en donde el segundo anticuerpo no comprende un dominio VH de un sitio de unión a antígeno para el resto efector; en donde dicho dominio VH del primer anticuerpo y dicho dominio VL del segundo anticuerpo juntos son capaces de formar un sitio de unión a antígeno funcional para el resto efector.
