Transmission of amyloid-β protein pathology from cadaveric pituitary growth hormone

We previously reported1 the presence of amyloid-β protein (Aβ) deposits in individuals with Creutzfeldt–Jakob disease (CJD) who had been treated during childhood with human cadaveric pituitary-derived growth hormone (c-hGH) contaminated with prions. The marked deposition of parenchymal and vascular Aβ in these relatively young individuals with treatment-induced (iatrogenic) CJD (iCJD), in contrast to other prion-disease patients and population...
