Immunohistochemical staining of Helicobacter heilmannii in the stomach of FcRn−/− and FcRn+/+ mice 4 weeks after H. heilmannii infection. Immunohistological examination of the gastric mucosa from FcRn+/+ and FcRn−/− mice (each n=5) 4 weeks after H. heilmannii infection was performed by confocal laser scanning microscopy. The stomach was treated as described in the Figure legend of Figure 4, and the selected serial sections were stained with polyclonal rabbit anti-H. pylori antibody in a blind manner. Green: H. heilmannii, red: F-actin, and blue: nucleus. Original magnification × 630. Typical images are shown. FcRn, neonatal Fc receptors for IgG.
