Abstract
En la presente se proporcionan anticuerpos anti-PILRA con la selectividad altamente deseable: que tienen una unión comparable a las proteínas PILRA humanas y cynomolgus, pero una unión mucho más débil a la proteína PILRB humana, así como una unión a las variantes PILRA G78 y R78. Los perfiles de unión y selectividad de los anticuerpos descritos en la presente permiten que se utilicen en estudios en animales (por ejemplo, monos) sin la necesidad de depender de una molécula sustituta y también cuando se trata a sujetos con cualquiera de las variantes de PILRA. En la presente se describen adicionalmente, por primera vez, los descubrimientos biológicos relacionados con PILRA y los efectos de la reducción de la señalización de PILRA en las células. Reivindicación 1: Un anticuerpo aislado o fragmento de unión a antígeno de este que se une específicamente a un receptor a tipo 2 similar a la inmunoglobulina emparejado de mono cynomolgus (cynoPILRA), en donde la afinidad de unión para cynoPILRA es al menos 2 veces mayor que la afinidad de unión para un receptor b tipo 2 similar a la inmunoglobulina emparejado humano (hPILRB). Reivindicación 67: Un método para tratar una enfermedad neurodegenerativa en un sujeto, que comprende administrarle al sujeto el anticuerpo aislado o fragmento de unión al antígeno de este de cualquiera de las reivindicaciones 1 a 59 o la composición farmacéutica de la reivindicación 61. Reivindicación 88: Una línea celular IPSC o célula madre pluripotente inducida por humanos modificada genéticamente (IPSC), en donde el IPSC se ha modificado para expresar dos copias del gen que codifica la variante R78 o la variante G78 de una proteína PILRA.
