Transgenic mice expressing hamster prion protein produce species-specific scrapie infectivity and amyloid plaques.

Abstract

Three transgenic mouse lines designated Tg 69, 71, and 81 were produced harboring a Syrian hamster (Ha) prion protein (PrP) gene; all expressed the cellular HaPrP isoform in their brains. Inoculation of Tg 81 mice or hamsters with Ha prions caused scrapie in integral of 75 days; nontransgenic control mice failed to develop scrapie after greater than 500… (More)
