Interleukin(IL)-36α and IL-36γ Induce Proinflammatory Mediators from Human Colonic Subepithelial Myofibroblasts

BACKGROUND Interleukin (IL)-36 cytokines are recently reported member of the IL-1 cytokine family. However, there is little information regarding the association between IL-36 cytokines and gut inflammation. In the present study, we investigated the biological activity of IL-36α and IL-36γ using human colonic subepithelial myofibroblasts (SEMFs). METHODS The mRNA expression and the protein ex...

Proinflammatory cytokines induce crosstalk between colonic epithelial cells and subepithelial myofibroblasts: implication in intestinal fibrosis.

BACKGROUND AND AIMS Colonic epithelial cells and adjacent subepithelial myofibroblasts are important counterparts in the pathogenesis of intestinal inflammation and fibrosis. We investigated the possible crosstalk between them, whilst focusing on the mucosal inflammation pathways that potentially trigger intestinal fibrosis. METHODS We studied the effects of proinflammatory cytokines (IL-1α, ...

Interleukin (IL)-1β Is a Strong Inducer of IL-36γ Expression in Human Colonic Myofibroblasts.

BACKGROUNDS AND AIMS Interleukin (IL)-36 cytokines are members of the IL-1 cytokine family. In this study, we investigated the expression of IL-36γ in human colonic myofibroblasts to explore the molecular mechanisms underlying IL-36γ induction. MATERIALS AND METHODS IL-36 mRNA was analyzed by real-time PCR method. Secretion of IL-36γ protein was evaluated by Western blot and ELISA analyses. M...

Interleukin-31 stimulates production of inflammatory mediators from human colonic subepithelial myofibroblasts.

Interleukin (IL)-31 is mainly produced by CD4+ T cells, in particular T cells skewed toward a Th2 phenotype. Here we report for the first time that IL-31 stimulates secretion of proinflammatory cytokines, chemokines and matrix metalloproteinases (MMPs) from human colonic subepithelial myofibroblasts (SEMFs). The effects of IL-31 were investigated by cDNA microarrays, enzyme-linked immunosorbent...

Regulation of proliferation of human colonic subepithelial myofibroblasts by mediators important in intestinal inflammation.

An increase in myofibroblast number may be necessary for wound healing but may also lead to postinflammatory scarring. We have, therefore, studied the role of mediators important in inflammatory bowel disease in regulating proliferation of human colonic myofibroblasts. Using primary cultures of these cells, we have shown increases in [3H]thymidine incorporation in response to platelet-derived g...
