    In Crohn’s disease (CD) and ulcerative colitis (UC), the two major forms of inflammatory bowel disease (IBD) in human beings, the pathological process is driven by an excessive immune response that is directed against components of the luminal flora and inappropriately controlled by immunesuppressive mechanisms. One such a mechanism involves TGF-β1, a pleiotropic cytokine that targets both immune and non-immune cells in the gut. TGF- β1 is highly expressed in inflamed mucosa of IBD patients but paradoxically it is unable to activate Smad-associated intracellular signalling and suppress inflammatory cytokine responses. This is because IBD-related inflammation is marked by elevated levels of Smad7, an inhibitor of TGF-β1 signalling. Consistently, knockdown of Smad7 with a specific antisense oligonucleotide restores TGF-β1 function, inhibits inflammatory cytokin.. View More»
