Abstract

Se proporcionan compuestos, métodos y composiciones farmacéuticas para reducir la cantidad o actividad de ARN de PRNP en una célula o animal y, en determinados casos, para reducir la cantidad de proteína PrP en una célula o animal. Dichos compuestos, métodos y composiciones farmacéuticas son útiles para mejorar al menos un síntoma o característica distintiva de una enfermedad neurodegenerativa. Dichos síntomas y características distintivas son cambios espongiformes en el cerebro, desarrollo de agregados proteicos anormales, pérdida neuronal, marcadores de pérdida neuronal, demencia que progresa rápidamente y muerte. Estas enfermedades neurodegenerativas incluyen enfermedades priónicas, enfermedad de Creutzfeldt-Jakob (CJD), variante de la enfermedad de Creutzfeldt-Jakob (vCJD), enfermedad de Creutzfeldt- Jakob familiar (fCJD), síndrome de Gerstmann-Straussler-Scheinker, insomnio familiar fatal, kuru, enfermedad de Alzheimer o enfermedad de Parkinson.
