The density of CD45RA+CD123+ plasmacytoid dendritic cells (PDCs) does not increase in the celiac lesion. Cryosections from duodenal mucosa were stained for CD123 and CD45RA. Density of PDCs was evaluated by superimposing a grid on sections and the number of CD45RA+CD123+ cells was calculated per mm2 lamina propria. Horizontal lines indicate median. HC, healthy controls; UCD, untreated celiac disease.
