Abstract
We conducted a population-based study in Ireland to address it.
We used the National Cancer Registry to collect data on all patients diagnosed with CRC in Ireland from 1994 to 2005 (n = 22,335) and identified those who also had IBD (n = 170). The clinical characteristics, treatment,...

Abstract
We found that MNV infection can accelerate bacteria-induced inflammatory bowel disease (IBD) progression in Mdr1a(-/-) mice. The studies presented here examined whether MNV infection also affects the phenotype of a bacterially driven mouse model of inflammation-associated colon cancer in genetically...

Abstract
We emphasize the major role of the Th17/IL-23 axis in dictating the perpetuation of intestinal inflammation, augmented by a failure of physiological control by regulatory T-cells. In conclusion, there is a central genesis of the defects underlying IBD, which therefore, in our opinion, is best accomm...

Abstract
Patients with inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease, are at increased risk of developing colon cancer, confirming that chronic inflammation predisposes to development of tumors. Moreover, it appears that colon cancers that do not develop as a com...

Abstract
We generated transgenic mice that constitutively express TL1A in T cells or dendritic cells. These mice spontaneously develop IL-13-dependent inflammatory small bowel pathology that strikingly resembles the intestinal response to nematode infections. These changes were dependent on the presence of a...

Abstract
We have recently shown that in IBD, there is a defective synthesis of the counter-regulatory cytokine, interleukin (IL)-25. In this study we investigated factors that control IL-25 production in the gut. IBD patients produced less IL-25 when compared with normal controls. Stimulation of normal intes...

Abstract
Interleukin-25 (IL-25) plays a key role in the initiation and expansion of T helper (Th) 2 cell-mediated immune responses, thereby contributing to allergic diseases and host defense against helminthic parasites. More recent studies have however shown that IL-25 can also control the f...
