Large intestine intraepithelial lymphocytes from Apc+/+ and Apc+/Min mice and their modulation by indigestible carbohydrates: the IL-15/IL-15R alpha complex and CD4+ CD25+ T cells are the main targets.

Abstract excerpt

We have shown recently that some indigestible carbohydrate (short-chain fructo-oligosaccharides [sc-FOS]) reduced colon tumor incidence in Apc+/Min mice, and that this effect depended on a functional local immune system. In addition, IL-15 mRNA was concomitantly modulated in the mucosa. Since intraepithelial lymphocytes (IELs) are in close contact with intestinal epithelial cells, these cells are the candidates...
