MICA expression in intestinal mucosa of CD patients.

A.- Representative immunoperoxidase staining of MICA/B in intestinal biopsy sections from pediatric CD patients with different degrees of lesion (mild, moderate and severe enteropathy; magnification 20×). B.- Immunohistochemical analysis for MICA/B expression in sections of intestinal biopsies from 27 pediatric patients. An arbitrary score of intensity of staining was used (from 0 to 4). The IC control antibody was defined as score zero. Each dot corresponds to the score obtained for each sample. * p≤0,05; ** p≤0,01 (Non parametric Kruskal wallis test followed by the Dunns multiple-comparison posttest).C.- Pattern of MICA/B expression along the epithelium on a mild enteropathy sample. Isotype Control (IC) is shown (magnification 40×).
