Reduced levels of transcripts of immune regulatory genes in the mucosa from gluten-sensitive patients (GS), but not celiac disease patients (CD). Expression of the indicated genes was measured by quantitative polymerase chain reaction assay (see Methods). Boxes represent the median (interquartile range) and whiskers represent the range of RNA levels relative to an 18S housekeeping gene in 19 GS, 12 CD and 8 dyspeptic controls (DC). *P < 0.05 relative to DC (Mann-Whitney U test).
