DC-LAMP+ DCs in the human antrum mucosa. Biopsy specimens were collected from 8 H. pylori-infected (Hp+) and 10 uninfected (Hp−) individuals, and expression of DC-LAMP was determined by immunoperoxidase staining. (A) Frequencies of DC-LAMP+ DCs, expressed as a percentage of the stained area in the gastric mucosa. Symbols represent individual values, and lines indicate the median. (B to E) Representative staining of DC-LAMP from uninfected (B) and H. pylori-infected (C to E) individuals. (F) Isotype control for staining in panel E. **, P < 0.01. Magnifications, ×20.
