Vasudevan, Anju Elkhal, Abdallah Inmunología Medicamentos - Investigación Producción Científica CD4(+) T cells are involved in the development of autoimmunity, including multiple sclerosis (MS). Here we show that nicotinamide adenine dinucleotide (NAD(+)) blocks experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, by inducing immune homeostasis through CD4(+)IFNγ(+)IL-10(+) T cells and reverses disease progression by restoring tissue integrity via remyelination and neuroregeneration. We show that NAD(+) regulates CD4(+) T-cell differentiation through tryptophan hydroxylase-1 (Tph1), independently of well-established transcription factors. In the presence of NAD(+), the frequency of T-bet(-/-) CD4(+)IFNγ(+) T cells was twofold higher than wild-type CD4(+) T cells cultured in conventional T helper 1 polarizing conditions. Our findings unravel a new pathway orchestrating CD4(+) T-cell differentiation and demonstrate that NAD(+) may serve as a powerful therapeutic agent for the treatment of autoimmune and other diseases. 2015-03-18T11:48:27Z 2015-03-18T11:48:27Z 2014 info:eu-repo/semantics/article Nature Communications, 2014, 5, Article number: 5101 2041-1723 http://uvadoc.uva.es/handle/10324/9465 10.1038/ncomms6101 Nature Communications 5 eng info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ Attribution-NonCommercial-NoDerivatives 4.0 International Nature Publish Group SI
