Previous studies have shown that ITF plays an important role in mucosal protection and repair. Coeliac disease represents a model of immune-mediated small intestinal inflammation and damage, with recovery on gluten-free diet. The aim of this study was to investigate the expression of ITF in the distal duodenal mucosa of subjects with coeliac disease, before and after treatment with a gluten-free diet. Expression of ITF and mucin in the distal duodenal biopsies from treated (n = 11) and untreated (n = 9) coeliac subjects and controls (n = 8) was investigated by immunohistochemistry and semiquantitative PCR. In untreated coeliac disease, there was reduction of ITF immunoreactivity in goblet cells but mucin expression was preserved. Mucosal recovery on gluten-free diet was associated with increased ITF immunoreactivity in goblet cells. There was also reduction in the expression of ITF transcripts, relative to MUC2 mRNA, in untreated coeliac duodenal samples, with recovery on gluten-free diet. Our study suggests that there is a selective reduction in the expression of the ITF gene in untreated coeliac disease. Recovery of ITF expression on a gluten-free diet suggests that the mucosal immune system regulates goblet cell differentiation and ITF expression in the human intestinal mucosa.<\/jats:p>","DOI":"10.1046\/j.1365-2249.2002.02011.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T10:34:16Z","timestamp":1047378856000},"page":"526-531","source":"Crossref","is-referenced-by-count":13,"title":["Selective
