Abstract

L'invention concerne des acides nucléiques, leurs dérivés et des substances de fixation spécifiques de séquences, qui inhibent l'expression de l'antigène CD30 et/ou de la S6 kinase ribosomale pp90rsk3. L'invention concerne également des compositions pharmaceutiques contenant de tels acides nucléiques, et l'utilisation de ces derniers pour la modulation de l'activation cellulaire, la suppression et la prévention des immunodysrégulations, la réduction de la charge virale, et l'éradication des cellules CD30+ et/ou pp90rsk3+ et de leurs tumeurs.
