Abstract

We previously reported 1 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 controls, allied with the ability of Alzheimer's disease brain homogenates to seed Aβ deposition in laboratory animals, led us to argue that the implicated c-hGH batches might have been contaminated with Aβ seeds as well as with prions. However, this was necessarily an association, and not an experimental, study in humans and causality could not be concluded. Given the public health importance of our hypothesis, we proceeded to identify and biochemically analyse archived vials of c-hGH. Here we show that certain c-hGH batches to which patients with iCJD and Aβ pathology were exposed have substantial levels of Aβ 40, Aβ 42 and tau proteins, and that this material can seed the formation of Aβ plaques and cerebral Aβ-amyloid angiopathy in intracerebrally inoculated mice expressing a mutant, humanized amyloid precursor protein. These results confirm the presence of Aβ seeds in archived c-hGH vials and are consistent with the hypothesized iatrogenic human transmission of Aβ pathology. This experimental confirmation has implications for both the prevention and the treatment of Alzheimer's disease, and should prompt a review of the risk of iatrogenic transmission of Aβ seeds by medical and surgical procedures long recognized to pose a risk of accidental prion transmission 2,3.

  • PD might be one of many neurological disorders involving prion protein aggregation and propagation.

    “Therefore, PD might be one of many neurological disorders involving prion protein aggregation and propagation [81].”

    From The gut–brain axis in early Parkinson’s disease: from prodrome to prevention (2025) · cites this paper as [81]

    The opening paragraph of the paper (page unavailable in our copy) says evidence from experimental models implicates the propagation of assemblies of misfolded proteins in Parkinson’s disease and other neurodegenerative conditions. It does not say that Parkinson’s disease involves aggregation or propagation of prion protein specifically; the cited evidence concerns other misfolded host proteins. (LLM, conf=0.85)

  • Human-to-human transmission of amyloid pathology is possible.

    “There is strong evidence that human-to-human transmission of amyloid pathology is possible.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
