Anti-Urease β 抗體說明書
Background: Helicobacter pylori is present in the stomachs of at least half of the world’s population. Although gastic adenocarcinoma is associated with the presence of H. pylori in the stomach, only a small fraction of colonized individuals develop this common malignancy. H. pylori urease, an enzyme that generates ammonia and is present within the lamina propria of colonized individuals, binds to class II major histocompatability complex （MHC） molecules on the surfaces of gastric epithelial cells in vitro. In addition, Urease, which may be toxic to gastic epithelial cells, may also induce apoptosis. Specifically, Urease plays a crucial role in the development of ulcers in the duodenum by accelerating apoptosis in the antral mucosa. Ammonia accelerates TNFα cytokineinduced apoptosis, while ammonia or urease alone are unable to induce apoptosis. Urease exists as two forms, Urease α （UreA） and Urease β （UreB）.
