Abstract

In the central nervous system, basement membrane (BM) constituents are predominantly associated with the vasculature. However, under inflammatory conditions, the expression of BM components may alter. Here, we investigated the distribution of several BM components, including laminin, collagen type IV and heparan sulfate proteoglycans in various multiple sclerosis (MS) lesions. We observed irregular and discontinuous BMs in active lesions. Throughout active MS lesions, we found dense networks of BM proteins, which were surprisingly not associated with the cerebrovasculature. These striking parenchymal networks were not observed in chronic inactive MS lesions and brains of non-neurological controls. In addition, we studied the distribution of transforming growth factor-beta1 (TGF-beta1), since it is known as a major modulator of ECM production. Leukocytes, in particular CD68-positive macrophages, expressed high levels of TGF-beta1 and were located in close proximity to parenchymal BM deposits in the MS lesions. We postulate that these BM networks may play a role in the further recruitment of inflammatory cells and form a barrier for axonal regeneration.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Increased number of PDGFRβ-expressing cells are detected in human MS pathology samples and increased ECM protein deposition is a common pathological feature of MS lesions.

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.
