La terapia emplea material genético con objeto de estimular la respuesta inmunológica, y su uso se ha asociado a una mayor supervivencia de los roedores, que fueron expuestos al agente causal del scrapie, encefalopatía espongiforme que afecta principalmente a ovejas y cabras.
La terapia se conoce como CpG oligodeoxinucleótido 1826, y se administró a los animales poco después de infectarlos con priones. Los autores, de la universidad Ludwig-Maximilians de Munich (Alemania), creen que la razón por la que el sistema inmune no ataca con normalidad a los priones se debe a que estas proteínas anómalas carecen de ácidos nucleicos.
En su experimento, observaron que los ratones tratados sobrevivieron un 38% más tiempo que los no tratados.
