Do lymphocytes in the human gastric mucosa during Helicobacter pylori have a T helper cell 1 phenotype?
These observations show that gastric T cells resemble the Th1 type, which may explain their failure to induce immunity to H. pylori and their ability to contribute to the pathogenesis of gastric disease.
These findings link altered expression of CLDN-1 to neoplastic transformation and suggest that CLDN-1 expression is associated with malignant canine thyroid tumors and their vascular invasion.
