A gluten-free diet lowers NKG2D and ligand expression in BALB/c and non-obese diabetic (NOD) mice.

ABSTRACT: The interplay between diet and immune parameters which could affect type 1 diabetes (T1D) pathogenesis is not sufficiently clarified. Intestinal up-regulation of the activating receptor natural killer group 2D (NKG2D) (CD314) and its ligands is a hallmark of coeliac disease. However, the direct effect of gluten on NKG2D expression is not known. We studied, by fluorescence activated cell sorter (lymphoid tissues) and reverse transcription-quantitative polymerase chain reaction (intestine and pancreatic islets), if a gluten-free diet (GF diet) from 4 weeks of age or a gluten-free diet introduced in breeding pairs (SGF diet), induced changes in NKG2D expression on DX5(+) (CD49b) natural killer (NK) cells, CD8(+) T cells and in intestinal and islet levels of NKG2D and ligands in BALB/c and non
