(736 citations, accompanying editorial). This article was the first randomized controlled trial that provided evidence that inhibition of integrins was effective as a therapeutic target in inflammatory bowel disease.

2. Sandborn WJ, Ghosh S, Panes J, Vranic I, Su C, Rousell S, Niezychowski W. Tofacitinib, an oral janus kinase inhibitor, in active ulcerative colitis. N Engl J Med 2012;367: 616-624. (239 citations). This article was the first randomized controlled trial that provided evidence that inhibition of JAK was effective as a therapeutic target in inflammatory bowel disease.

3. Shmakov AN, McLennan NF, McBride P, Farquhar CF, Bode J, Rennison KA, Ghosh S. Cellular prion protein is expressed in the human enteric nervous system. Nature Medicine 2000;6 :840-841. (41 citations). This article provided evidence for a route of intestinal transmission of infectious prion protein in variant Creutzfeldt Jakob disease. The entire field of interaction of infectious prion protein with the intestine was critically assessed in an invited review (Gut 2001; 48: 443-447).

4. Akbar A, Yiangou Y, Facer P, Walters JR, Anand P, Ghosh S. Increased capsaicin receptor TRPV1 expressing sensory fibres in irritable bowel syndrome and their correlation with abdominal pain. Gut 2008; 57:923-929. (287 citations, accompanying editorial). This showed the involvement of TRPV1 in visceral hypersensitivity of irritable bowel syndrome, the commonest gastrointestinal disorder. This is now potentially a therapeutic target.

5. Van Heel DA, Ghosh S, Butler M, Hunt KA, Lundberg A, Ahmad T, McGovern DPB, Onnie C, Negoro K, Goldthorpe S, Foxwell BMJ, Mathew CG, Forbes A, Jewell DP, Playford RJ. Muramyl dipeptide and toll-like receptor sensitivity in NOD2 associated Crohn’s disease. Lancet 2005;365: 1794-1796. (274 citations, accompanying editorial). This was the first study to show that NOD2 mutations, the first mutations associated with Crohn’s disease, are loss of function in human inflammatory bowel disease and suggested how this may relate to intestinal inflammation.

6. Ghosh S, Cowen S, Hannan WJ, Ferguson A. Low bone mineral density in Crohn’s disease but not in ulcerative colitis, at diagnosis. Gastroenterology 1994;107: 1031-1039. (259 citations). This article established for the first time that osteopenia in inflammatory bowel disease may be driven by inflammation directly, rather than only as a consequence of steroid therapy. Strategies for prevention of osteopenia cite this manuscript frequently.

7. van Heel DA, Ghosh S, Hunt K, Mathew C, Forbes A, Jewell D, Playford R. Synergy between TLR9 and NOD2 innate immune responses is lost in genetic Crohn’s disease. Gut 2005; 54: 1553-1557. (120 citations). Further evidence of loss of function of NOD2 mutation in human inflammatory bowel disease and relationship with intestinal inflammation. This is now a therapeutic target.
8. Akbar A, Yiangou Y, Facer P, Walters JRF, Brydon WG, Anand P, Ghosh S. Expression of the TRPV1 receptor differs in quiescent inflammatory bowel disease with or without abdominal pain. Gut 2010;59: 767-774. (64 citations) This studied provided an explanation for visceral hypersensitivity in patients with quiescent inflammatory bowel disease who continued to suffer from pain, a common problem which causes significant morbidity.

9. Marion R, Butler M, Dechelotte P, Playford R, Ghosh S. Comparison of cytokine modulation by natural PPAR gamma ligands with synthetic ligands in intestinal-like Caco-2 cells – potential for dietary modulation of PPAR in intestinal inflammation. Am J Clin Nutr 2008;87: 939-948.(56 citations) This study provided a mechanistic explanation for a target for dietary fatty acid modulation of inflammation in inflammatory bowel disease. We published an invited review on the topic summarizing all the research work (Gut 2009; 58: 586-593).

Eur J Immunol 2006; 36: 864-874. (61 citations) In this study we provided evidence that the tolerogenic phenotype of dendritic cells in the intestine may be modulated by close contact with intestinal epithelial cells in an in vitro model. We published an invited review on the mechanisms of tolerization of dendritic cells in the intestine (Gut 2009; 58: 1291-99).

Eur J Immunology 2005; 35: 2471-2476. (121 citations) In this study we demonstrated how TLR and NOD1 activation act synergistically to promote inflammation.

12. Shmakov A, Bode J, Kilshaw P, Ghosh S. Diverse expression of 67kD laminin receptor protein in human small intestine. J Pathol 2000; 191:318-322. (51 citations) In this study we provided evidence for potential transmission pathways for infectious prion protein via the intestine.

Gastroenterology 2004; 127: 1067-1075. (134 citations) I supervised my graduate student Emma Armitage for her doctorate of medicine thesis and I was the principal investigator for the MRC grant funding this study – it showed that deprivation as social status is protective for Crohn’s disease.

(51 citations) We showed in a randomized controlled trial that in addition to inhibition of integrins, inhibition of its ligand MAdCAM-1 was also effective as an anti-inflammatory agent in ulcerative colitis – these work led to introduction of anti-adhesion molecules as therapeutic agents in IBD.

(130 citations) I designed the study and analyzed the data which showed that a combination of anti-TNF monoclonal antibody and azathioprine is superior to either agent alone.
