Infectivity of amyloid diseases

Sigurdsson, Einar M, Wisniewski, Thomas, Frangione, Blas·2002·Trends in Molecular Medicine

Abstract

To date, transmissibility of amyloid diseases has not been thoroughly investigated. Although only some of these conformational disorders are considered infectious, all amyloid diseases could be infectious under certain conditions. For transmissibility, endogenous expression of an amyloidogenic peptide required, as well as the presence of an inoculum that is rich in amyloid fibrils and/or their precursors. Notably, administration of one type of amyloid might result in deposition of a different amyloid. Various cofactors could be essential for transmission - some might chaperone the amyloid peptides and/or fibrils, thereby directly facilitating their propagation; others might indirectly stabilize and/or increase levels of conformers with a high beta-sheet content. It is possible that these chaperones are induced by inflammation, which itself can lead to secondary amyloidosis. Thus, amyloid-related therapeutic approaches should not be based on administration of amyloidogenic peptides in conjunction with an inflammatory stimulus, such as in a recently halted clinical trial for Alzheimer's disease.

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.
