Abstract

La presente solicitud se refiere a determinados anticuerpos anti-PAD4 (peptidil arginina deiminasa 4), ácidos nucleicos que codifican los anticuerpos, vectores y células huésped que comprenden los ácidos nucleicos, y métodos para fabricar y utilizar los anticuerpos. Reivindicación 1: Un anticuerpo aislado que se une específicamente a la proteína arginina deiminasa 4 (PAD4), en el que el anticuerpo comprende una región variable de cadena pesada (VH) que comprende una región determinante de la complementariedad de cadena pesada 1 (HCDR1) que comprende la secuencia de aminoácidos de SEQ ID Nº 62 y una HCDR3 que comprende la secuencia de aminoácidos de SEQ ID Nº 6; y una región variable de cadena ligera (VL) que comprende una región determinante de la complementariedad de cadena ligera 1 (LCDR1) que comprende la secuencia de aminoácidos de SEQ ID Nº 7. Reivindicación 46: Una composición farmacéutica que comprende un anticuerpo de cualquiera de las reivindicaciones 1 - 45 y un vehículo farmacéuticamente aceptable. Reivindicación 47: Un ácido nucleico aislado o un conjunto de dos o más ácidos nucleicos que codifican el anticuerpo de cualquiera de las reivindicaciones 1 - 45. Reivindicación 48: Un vector aislado que comprende uno o más ácidos nucleicos que codifican la cadena pesada y la cadena ligera del anticuerpo de cualquiera de las reivindicaciones 1 - 45. Reivindicación 49: Una célula huésped aislada que comprende el ácido nucleico de la reivindicación 47 o el vector de la reivindicación 48. Reivindicación 50: Un método para producir un anticuerpo que se une específicamente a PAD4 que comprende cultivar la célula huésped de la reivindicación 49 en condiciones adecuadas para la expresión del anticuerpo.
