Fig. 4From: More fuel to the fire: some patients with non-celiac self-reported wheat sensitivity exhibit adaptive immunological responses in duodenal mucosaCytokines that induce and maintain Th17 polarization. a–d left panel: Representative immunoperoxidase photomicrographs of control, non-celiac self-reported wheat sensitivity (NCSRWS) and celiac disease (CD). Arrows depict a IL-17A, b IL-21, c IL-22 and d IL-23 immunoreactive cells. Original magnification was × 320. a–d, right panel: Relative percentage expression of a IL-17A, b IL-21, c IL-22 and d IL-23. Results are expressed as the mean (yellow line), median (black line), and 5th/95th percentilesBack to article page
