Abstract

Multiple sclerosis (MS) is an idiopathic chronic inflammatory demyelinating disease of the central nervous system with variable extent of remyelination. Remyelination originates from oligodendrocyte (OG) precursor cells, which migrate and differentiate into mature OG. Tubulin polymerization promoting protein (TPPP/p25) is located in mature OG and aggregates in oligodendroglial cytoplasmic inclusions in multiple system atrophy. We developed a novel monoclonal anti-TPPP/p25 antibody to quantify OG in different subtypes and disease stages of MS, and possible degenerative changes in OG. We evaluated autopsy material from 25 MS cases, including acute, primary progressive, secondary progressive, relapsing remitting MS, and five controls. Demyelinated lesions revealed loss of TPPP/p25-positive OG within the plaques. In remyelination, TPPP/p25 was first expressed in OG cytoplasms and later became positive in myelin sheaths. We observed increased numbers of TPPP/p25 immunoreactive OG in the normal appearing white matter (NAWM) in MS patients. In MS cases, the cytoplasmic area of TPPP/p25 immunoreactivity in the OG was higher in the periplaque area when compared with NAWM and the plaque, and TPPP/p25 immunoreactive OG cytoplasmic area inversely correlated with the disease duration. There was a lack of phospho-TDP-43, phospho-tau, α-synuclein, and ubiquitin immunoreactivity in OG with enlarged cytoplasm. Our data suggest impaired differentiation, migration, and activation capacity of OG…

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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 densities of TPPP/p25 myelin-maintaining oligodendrocytes have previously been demonstrated in normal-appearing white matter in autopsy tissue of patients with chronic MS.

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.
