Abstract

Esta solicitud se refiere generalmente a la producción de dominios a1-a2 no naturales modificados de ligandos NKG2D con polipéptidos unidos que tienen propiedades de unión a objetivo específicas, por ejemplo, anticuerpos o fragmentos de anticuerpos variables, que se administran selectivamente a receptores de antígenos quiméricos (CARs) compuestos por receptores de NKG2D no naturales modificados en células de mamífero manipuladas. El direccionamiento de moléculas expresadas en la superficie incluye aquellas de células infectadas por virus que luego pueden ser atacadas y eliminadas por células manipuladas del sistema inmunitario que expresan CARs afines a los dominios a1-a2 no naturales modificados de ligandos NKG2D con polipéptidos unidos.
