Abstract

The paracaspase MALT 1 is a major player in lymphocyte activation and proliferation. MALT1 mediates Ag-induced signaling to the transcription factor NF-κB by functioning both as a scaffold protein and cysteine protease. We studied the role of MALT1 in the development of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. MALT1-knockout mice did not develop any clinical symptoms of EAE. In addition, lymphocyte and macrophage infiltration into the spinal cord was absent in MALT1-knockout mice, as were demyelination and proinflammatory gene expression. Adoptive transfer experiments showed that MALT1 deficiency in splenocytes is sufficient for EAE resistance. Moreover, autoreactive T cell activation was severely impaired in MALT1-deficient T cells, suggesting the inability of MALT1-deficient effector T cells to induce demyelinating inflammation in the CNS. Finally, the MALT1 substrates A20 and CYLD were completely processed in wild-type T cells during EAE, which was partially impaired in MALT1-deficient T cells, suggesting a contribution of MALT1 proteolytic activity in T cell activation and EAE development. Together, our data indicate that MALT1 may be an interesting therapeutic target in the treatment of multiple sclerosis.

  • Mutations in downstream molecules involved in SYK signaling, including BCL10 and MALT1, have also been associated with MS risk.

    “Likewise, mutations in downstream molecules involved in SYK signaling, including BCL10 and MALT1, have also been associated with MS risk (Mc Guire et al., 2013; Molinero et al., 2012).”

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.
