摘要: The present invention relates to treatment or prevention of radiation induced fibrosis using TNF-alpha antagonism. Preferably, TNF-alpha is antagonized by direct binding or by inhibition of synthesis. In a preferred embodiment, the invention comprises intraperitoneal administration of a chitosan-siRNA nanoparticle, wherein the siRNA is targeted to the mRNA encoding TNF-alpha.

摘要: The present invention relates to dehydrated nanoparticles comprising chitosan and a nucleic acid. Preferably, the nucleic acid is a siRNA. Dehydrated nanoparticles of the invention have improved storage characteristics. The particles may be used in screening methods, e.g. where they have been dried onto a solid support, such as the surface of a culture well. The nanoparticles may also be dried onto implants for tissue engineering scaffolds, where they enable transfection of cells growing on the scaffold. Moreover, the particles have therapeutic relevance.
