In vitro organ culture of treated coeliac disease (CD) intestine: effect of 24 hour gliadin challenge on enterocyte expression of FAS. (A) FAS expression after 24 hour challenge with medium alone. Faint staining is observed on cell membranes of some enterocytes. (B) FAS expression after 24 hour challenge with gliadin. Intense FAS expression is evident on the cell membranes of the majority of enterocytes and in some lamina propria mononuclear cells. (C) FAS expression after 24 hour challenge with gliadin: high magnification. Staining is evident on the basolateral membranes of the enterocytes. Original magnification: A, B (×160); C (×240); immunohistochemistry, peroxidase staining technique.
