Three risk loci shared with ankylosing spondylitis and psoriasis (the MHC class I region, ERAP1 and IL23R and the MHC class I-ERAP1 interaction), as well as two loci shared with inflammatory bowel disease (IL23R and IL10) implicate shared pathogenic pathways in the spondyloarthritides and Behçet's disease.
Moreover, adoptive transfer of CD69<sup>+</sup> Tregs but not CD69<sup>-</sup>Tregs or CD69<sup>+</sup> Tregs deficient in IL-10 dramatically prevented the development of inflammatory bowel disease (IBD) in mice.
We identified a homozygous, splice-site point mutation in IL10RA in an infantile-onset IBD patient causing a premature stop codon (P206X) and IL-10 insensitivity.
We describe a child presenting with intractable bloody diarrhoea since 2 weeks of age and with severe nappy ulceration, who was ultimately diagnosed as having inflammatory bowel disease (IBD) due to an immunodeficiency in the IL-10 receptor.
The objectives of this work were to study the mechanisms of the inflammatory bowel disease (IBD) in HLA-B27 rats and to determine the effects of treatment with IL-10.
In this study, we investigated the role of inflammasome activation in the development of chronic intestinal inflammation by utilizing interleukin-10 (IL-10) knockout (KO) mouse as an animal model, which develops chronic colitis resembling human IBD.
We observed that C3H ASF and 129 ASF IL-10 are more sensitive towardB7 600 μg/mL vitamin B<sub>3</sub> and 1,200 μg/mL vitamin C. The lowest growth rate and viability for all types of organoids was with 1,200 μg/mL vitamin C. From quantitative polymerase chain reaction analysis (qPCR analysis), MUC2 was upregulated for 129 ASF and C3H Conv when exposed to 600 μg/mL and 1,200 μg/mL vitamin C. It suggests that large amounts of glycoprotein may be produced after adding high concentrations of vitamin C. Since inflammatory bowel disease has low level of MUC2, this finding may be helpful in restoring mucosal health by upregulating the MUC2 gene while altering patient's microbiota (Sibila et al., Annals of the American Thoracic Society, 2016).
These results suggest that IL-10 production by ManLAM-treated B cells contributes to keeping the balance between CD4<sup>+</sup> T cell subsets and protect mice from DSS-induced IBD.
Thus our results demonstrate that both IBD and CRC are linked with an intensified production of a wide array of monocyte/macrophage pro-inflammatory cytokines which is not accompanied by elevated levels of circulating IL-10, except for its insufficiently inhibitory elevation in UC patients.
Mutations in interleukin-10 and its receptors cause infantile inflammatory bowel disease (IBD), a hyperinflammatory disorder characterized by severe, treatment-refractory colitis, multiple abscesses, and enterocutaneous fistulas.
We investigated two main types of Tregs, the CD4+FOXP3+ and IL-10+ Tr1, in pediatric subjects with inflammatory bowel disease (IBD) both at diagnosis and after the clinical remission.
Employing a TNFα-driven murine inflammatory bowel disease (IBD) model (TNF<sup>ΔARE/+</sup>), which mirrors the Treg expansion and transmural ileitis seen in Crohn's disease, we demonstrate that the TNFα-mediated loss of Treg suppressive function coincides with induction of a specific miRNA, miR-106a in both humans and mice, via NFκB promoter binding to suppress post-transcriptional regulation of IL-10 release.
The main goal of this clinical trial is the local liposome-mediated gene transfer of these two antiinflammatory cytokines, interleukin 4 and interleukin 10, in patients with severe IBD of the rectum.
