A praziquantel treatment study of immune and transcriptome profiles in Schistosoma haematobium-infected Gabonese schoolchildren Instituut voor Tropische Geneeskunde
Background. Although Schistosoma haematobium infection has been reported to be associated with alterations in immune function, in particular immune hyporesponsiveness, there have been only few studies that have used the approach of removing infection by drug treatment to establish this and to understand the underlying molecular mechanisms.
Methods. Schistosoma haematobium-infected schoolchildren were studied before and after ...
Reciprocal changes of Foxp3 expression in blood and intestinal mucosa in IBD patients responding to infliximab KU Leuven
BACKGROUND: Immune therapies may act in inflammatory bowel diseases (IBD) by modulating regulatory T cells (Tregs). Therefore, we investigated the effect of infliximab (IFX) therapy on Forkhead box protein3 (Foxp3) T cells in blood and intestinal mucosa from Crohn's disease (CD) and ulcerative colitis (UC). METHODS: Forty patients with active IBD (23 CD / 17 UC) were treated with IFX 5 mg/kg intravenously at weeks 0, 2, 6, and each 8 weeks ...
Idd13 is involved in determining immunoregulatory DN T-cell number in NOD mice KU Leuven
Immunoregulatory T cells have been identified as key modulators of peripheral tolerance and participate in preventing autoimmune diseases. CD4(-)CD8(-) (double negative, DN) T cells compose one of these immunoregulatory T-cell subsets, where the injection of DN T cells confers protection from autoimmune diabetes progression. Interestingly, genetic loci defining the function and number of CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs) coincide ...
Dietary supplementation with high doses of regular vitamin D3 safely reduces diabetes incidence in nod mice when given early and long-term KU Leuven
High doses of the active form of vitamin D3, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) prevent diabetes in the non-obese diabetic (NOD) mouse but also elicit unwanted calcemic side-effects. Because immune cells themselves can convert vitamin D3 into 1,25(OH)2D3 locally, we hypothesized that dietary vitamin D3 can also prevent disease. Thus, we evaluated whether dietary administration of high doses of regular vitamin D3 (800 IU per day) during ...
