  • IL-2 receptor expression on gastric mucosa T lymphocytes in enhanced in duodenal ulcer patients compared with non-ulcer dyspeptic patients
    Ihan, Alojz ...
    Helicobacter pylori infects an estimated 50% of the world population, however only a small proportion of individuals develop clinical symptoms of gastritis, peptic ulceration or gastric cancer. The ... variations in disease presentation may be due to differences in bacterial virulence and/or immune response to the pathogen. This study examined the expression of IL-2 receptor and ICAM-1 molecules on gastric mucosa infiltrating T lymphocytes in two groups of H. pylori infected patients: one group with an active ulcer disease and the other with non-ulcerative chronic gastritis. T lymphocytes were isolated from gastric mucosa biopsies by using mechanical and enzymatic tissue desegregation. Ficoll-puriffied lymphocytes were incubated with monoclonal antibodies and analyzed by using 3-color flow cytometry analysis for the IL-2 receptor (CD25) and ICAM-1 molecule (CD54) expression. Lymphocytes from 37 Helicobacter pylori infected patients with severe gastric mucosa infiltration (G2 and G3 histological type in Sydney classification) were analyzed; 18 patients had at least 5-year history of duodenal ulcer disease (group A) and 19 patients had at least 3-year history of non-ulcer dyspeptic disease (group B). ...
