Analysis of lymphocyte composition in the gastric mucosa with a gastric cancer developed after eradication of Helicobacter pylori - Analysis of lymphocyte composition in the gastric mucosa

The lymphocyte subsets of the antrum and lesser curvature of the body were similar. In contrast, compared to those in the greater curvature of the gastric body, CD4+/CD3+ lymphocyte subsets were elevated in the lesser curvature of the body, whereas CD8+/CD3+, CD7+/CD3+, CCR4+/CD3+, CD45RA+/CD3+CD4+, and CD45RA+/CD3+CD4- were lower. Linear regression analysis showed a negative correlation between the time after H. pylori eradication and CD4+/CD3+.
