Figure 1From: Maternal celiac disease autoantibodies bind directly to syncytiotrophoblast and inhibit placental tissue transglutaminase activityA) Immunohistochemical staining (brown with blue hematoxylin counterstain) showing IgA from CD serum binding at the syncytial (maternal) surface of term placenta; B) binding is abolished by preincubation of serum with recombinant tissue transglutaminase; C) negative control serum fails to stain. Scale bar: 250 μm (a, c), 60 μm (b).Back to article page
