Hanson, MD, PhD a, Olle Magnusson, MD, PhD e, Ulf Bengtsson, MD, PhD b, Esbjörn Telemo, PhD a  Journal of Allergy and Clinical Immunology  Volume 109, Issue 5, Pages (May 2002) DOI: /mai Copyright © 2002 Mosby, Inc.

2 Fig. 2 Immunostaining of duodenal biopsies from food-allergic patients and controls. Red-brown color indicates positive staining; blue color indicates counterstaining of nuclei. Black bars indicate 100 μm. A, CD3+ T cells in a nonchallenged patient without symptoms. B, Marked increase of CD3+ T cells in a challenged patient with symptoms. C, Presence of IgE-stained cells in a nonchallenged patient without symptoms. D, Enhanced presence of IgE-stained cells in a challenged patient with symptoms. E, MBP-stained eosinophils in a nonchallenged patient without symptoms; note nonspecific staining of mucus in goblet cells. F, Marked increase of MBP-stained eosinophils in a challenged patient with symptoms. G, MBP-stained eosinophils (as in Fig 1, F ) at higher magnification; note MBP-containing granules free in the tissue. H, CD3+ T cells in a control. I, IgE-stained cells in a control. J, MBP-stained eosinophils in a control. K, Isotype control staining. Journal of Allergy and Clinical Immunology  , DOI: ( /mai ) Copyright © 2002 Mosby, Inc. Terms and Conditions

3 Fig. 1 Numbers of MBP+ eosinophils (A ), IgE-stained cells (B ), CD3+, CD4+, and CD8+ T cells (C ), IL-4-stained cells (D ), and IFN-γ-stained cells (E ) in duodenal biopsy specimens taken from healthy controls and SPT-negative/s-IgE Ab-negative patients with and without symptoms (n = 11). Results are expressed as individual data points, and the medians are indicated. Three patients with positive SPT results/positive s-IgE Ab and their healthy controls are included as references (black dots) . *P < .05. **P < ***P < .001.
