IL1B and Huntington disease: Remarkably, when we analyzed cytokine secretion by MoDC (from HD, UC and CD) only infected with single probiotic strains alone, our results displayed undetectable or very low cytokine levels, except for B2, which induced secretion of high levels of IL-23, IL-1β and IL-10 selectively in CD-derived MoDC (Supplementary Figure S3).
