Re-expression of PSA-NCAM by demyelinated axons: an inhibitor of remyelination in multiple sclerosis?
Abstract
Multiple sclerosis is affecting approximately 1 out of every 1000 individuals in the western world. After axons are denuded of myelin in the early stages of the disease, remyelination occurs, but eventually this process fails, and permanent disability is the result. During development, the polysialylated form of the neural cell adhesion molecule NCAM, PSA-NCAM, is expressed at the axonal surface and acts as a negative regulator of myelination, presumably by preventing myelin-forming cells from attaching to the axon. Removal of PSA-NCAM from the axonal surface is a prerequisite for the initiation of myelination. We questioned whether, in multiple sclerosis, re-expression of PSA-NCAM by axons could occur, and therefore account for the failure of remyelination. Forty multiple sclerosis lesions from 24 different post-mortem multiple sclerosis cases were selected by histological methods and analysed by immunohistochemistry. Demyelinated lesions and partially remyelinated lesions (shadow plaques) were studied. Controls consisted of post-mortem brain tissue from patients with amyotrophic lateral sclerosis and without neurological disease. We showed that PSA-NCAM, normally absent from adult brain, is re-expressed on demyelinated axons in the plaques. Within shadow plaques, remyelinated axons do not express PSA-NCAM. Re-expression of PSA-NCAM could act as an inhibitor of remyelination and participate in disease progression in multiple sclerosis.

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.
