Inhibition of miR-142-5P ameliorates disease in mouse models of experimental colitis.

Background: MicroRNAs (miRNAs) are epigenetically involved in regulating gene expression. They may be of importance in the pathogenesis of inflammatory bowel disease (IBD). The aim of this study was to determine the role of miRNAs by their specific blocking in the CD4+CB45RBhi T-cell transfer model of chronic experimental colitis.

Effect of interleukin-17 on gene expression profile of fibroblasts from Crohn's disease patients.

Background And Aim: The expression of interleukin (IL)-17 is upregulated in inflammatory bowel disease (IBD). Since fibroblasts are known to be responsive to IL-17, they may play a role in the modulation of inflammatory responses in IBD. Here, the effects of IL-17 on ileum and colon fibroblasts from Crohn's disease (CD) and ulcerative colitis (UC) patients are investigated, as compared to controls.

Analysis of cytokines and chemokines produced by whole blood, peripheral mononuclear and polymorphonuclear cells.

Cytokines are immunomodulating proteins involved in cellular communication. The levels of different cytokines reflect the immune capabilities of a person. In literature both whole blood and peripheral blood mononuclear cells (PBMCs) are used, which might lead to different results.
