Expression of mucosal addressin cell adhesion molecule 1 on vessel endothelium of gastric mucosa in patients with nodular gastritis

Figure 1 (A): H pylori-negative gastric mucosa showed little immunoreactivity for mucosal addressin cell adhesion mol-ecule 1 (MAdCAM-1). MAdCAM-1 was expressed on the en-dothelium of numerous vessels within the lamina propria with H pylori infection (B), particularly in association with dense mononuclear infiltration (C). Strong endothelial expres-sion of MAdCAM-1 was localized on high endothelial venule-like vessels adjacent to the lymphoid follicles D.
