Enhanced detection and retrograde axonal transport of PrPc in peripheral nerve

Abstract

Neuroinvasion of the CNS during orally acquired transmissible spongiform encephalopathies (TSEs) may involve the transport of the infectious agent from the periphery to the CNS via the peripheral nerves. If this occurs within axons, the mechanism of axonal transport may be fundamental to the process. In studies of peripheral nerve we observed that the cellular prion protein (PrPc) is highly resistant to detergent extraction. The implication of this is an underestimation of the abundance of PrPc in peripheral nerve. We have developed nerve extraction conditions that enhance the quantification of the protein in nerve 16-fold. Application of these conditions to evaluate the accumulation of PrPc distal to a cut nerve now reveals that PrPc is retrogradely transported from the axon ending. These results provide a potential cellular mechanism for TSE infectivity to gain entry to the CNS from the periphery.

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.
