Abstract

The ability to selectively block the entry of leukocytes into the central nervous system (CNS) without compromising the immune system is an attractive therapeutic approach for treating multiple sclerosis (MS). Using endothelial CD146-deficienct mice as a MS model, we found that endothelial CD146 plays an active role in the CNS-directed extravasation of encephalitogenic T cells, including CD146(+) TH1 and TH17 lymphocytes. Moreover, treating both active and passive MS models with the anti-CD146 antibody AA98 significantly decreased the infiltrated lymphocytes in the CNS and decreased neuroinflammation. Interestingly, the ability of AA98 to inhibit the migration of CD146(+) lymphocytes was dependent on targeting endothelial CD146, but not lymphocytic CD146. These results suggest a key molecular target located on the blood-brain barrier endothelium that mediates the extravasation of inflammatory cells into the CNS. In addition, our data suggest that the AA98 is a promising candidate for treating MS and other CNS autoimmune diseases.

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

  • MCAM can facilitate the accumulation of autoreactive T cells in the CNS during MOG33-55 EAE.

    “Another adhesion molecule that can facilitate the accumulation of autoreactive T cells in the CNS during MOG33-55 EAE is melanoma cell adhesion molecule (MCAM) (122, 123).”
  • Injection of anti-MCAM antibodies into mice reduces the severity of EAE, demonstrating the importance of MCAM in disease pathogenesis.

    “Injection of anti-MCAM antibodies into mice also reduces the severity of EAE, demonstrating the importance of this adhesion molecule in disease pathogenesis (122, 123).”

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.
