Relation of Neutrophil infiltration and H pylori infection and EBV infection.
(A) Images of H. pylori infection showed by a general H. pylori antibody and the H. pylori CagA antibody staining. Scale Bar, 50 μm. (B) Neutrophil MPO staining in 3 pairs of cancer adjacent tissues (positive for H. pylori) and corresponding cancer tissues. Scale Bar, 300 μm. (C) Two images of gastric cancer samples positive for EBV infection. Magnified images showed the nuclear localized EBER1/2 in situ hybridization signals. Scale Bar, 100 μm. (D) Neutrophil MPO staining of 6 EBV positive gastric cancer samples. Scale Bar, 300 μm. Positive control experiments for CagA antibody and EBER in situ could be found in Supplementary Fig. 2 and Fig. 3.
