Abstract

La presente invención se refiere a moléculas de unión monocatenarias multidominio. Las moléculas comprenden i) un dominio de unión de péptido-complejo mayor de histocompatibilidad (pMHC) que se une a un complejo SLLQHLIGL (SEQ ID Nº 1) HLA-A*02, donde el dominio pMHC comprende una primera región variable unida a una región constante (VC1) y una segunda región variable unida a una región constante (VC2); ii) un dominio efector inmunitario que se acopla a células T que comprende una región variable de cadena ligera de anticuerpo (TCE-VL) y una región variable de cadena pesada de anticuerpo (TCE-VH); y iii) un dominio de extensión de la vida media que comprende una primera región Fc de IgG (FC1) y una segunda región Fc de IgG (FC2), donde la región FC1 y la región FC2 se dimerizan para formar un dominio Fc. Las moléculas de unión se pueden usar para tratar enfermedades tales como el cáncer. Reivindicación 1: Una molécula de unión monocatenaria multidominios que comprende: i) un dominio de unión de péptido-complejo mayor de histocompatibilidad (pMHC) que se une a un complejo SLLQHLIGL (SEQ ID Nº 1) HLA-A*02, donde el dominio pMHC comprende una primera región variable unida a una región constante (VC1) y un segunda región variable unida a una región constante (VC2), donde VC1 y VC2 se dimerizan para formar el dominio de unión de pMHC; ii) un dominio efector inmunitario que se acopla a células T que comprende una región variable de cadena ligera de anticuerpo (TCE-VL) y una región variable de cadena pesada de anticuerpo (TCE-VH); y iii) un dominio de extensión de la vida media que comprende una primera región Fc de IgG (FC1) y una segunda región Fc de IgG (FC2), donde la región FC1 y la región FC2 se dimerizan para formar un dominio Fc; donde el dominio efector inmunitario que se acopla a las células T está unido al extremo N-terminal de VC1, VC1 está unida a través de su extremo C-terminal al extremo N-terminal de la región FC1, la región FC1 está unida a través de su extremo C-terminal al extremo N-terminal de VC2, y VC2 está unida a través de su extremo C-terminal al extremo N-terminal de la región FC2; y donde el dominio de unión de pMHC y el dominio efector inmunitario que se acopla a las células T son capaces de unirse a un complejo pMHC y a una célula T, respectivamente. Reivindicación 38: Un ácido nucleico que codifica la molécula de unión multidominio de cualquiera de las reivindicaciones anteriores. Reivindicación 39: Un vector de expresión que comprende el ácido nucleico de la reivindicación 38.
