Revamp of brain 'could slow CJD'
Scientists believe they could slow the progress of "mad cow disease" by genetically "revamping" the brain.
Tests in mice with scrapie - a disease similar to CJD in humans and BSE in cattle - showed the life-extending treatment works.
The method used by the German team involves molecules called special RNAs (siRNAs), Journal of Clinical Investigation reports.
These shut down the production of proteins that go awry in prion disease.
