Abstract

For decades Experimental Autoimmune Encephalitis (EAE) has remained as an unsurpassed multiple sclerosis (MS) animal model. C-Phycocyanin (C-Pc) has been reported to exhibit pharmacological properties that may be expected to symptomatically improve EAE and MS. However, in this paper we reveal a basic underlying mechanism that may provide a new approach to the rationale of the overall beneficial effect of this natural antioxidant. We demonstrate that C-Pc is able to trigger mechanisms preventing or downgrading EAE expression and induces a regulatory T cell (Treg) response, in peripheral blood mononuclear cells (PBMC) from MS patients. These results agree with reports suggesting that Treg limit acute MS attacks and that C-Pc may act as a neuroprotector and thereby reverts the organic and functional damage in neurodegenerative disorders of the central nervous system (CNS). Moreover, evidence is provided on the antioxidant activity of C-Pc within the CNS, intended to improve the myelin and axonal damage of EAE induced Lewis rats. Our results indicate that specific Treg activation may represent a central and essential mechanism in supporting the therapeutic potential of C-Pc for MS and may lead to new and more effective therapies; this property would then complement and enhance other proven active principles such as interferons (IFN), giving rise to combined therapies.

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.
