Increased numbers of Foxp3-positive regulatory T cells in gastritis, peptic ulcer and gastric adenocarcinoma

Figure 5 Box plots for the number of CD25⁺, CD4⁺, and Foxp3⁺ cells, and the ratio of CD25⁺/CD4⁺ and of Foxp3⁺/CD4⁺ in gastritis and peptic ulcer patients with and without intestinal metaplasia. Box plots for A: The number of CD25⁺ cells; B: The number of CD4⁺ cells; C: The number of Foxp3⁺ cells; D: The ratio of CD25⁺/CD4⁺; E: The ratio of Foxp3⁺/CD4⁺ in non-intestinal metaplasia (IM) areas of antral gastric mucosa from gastritis (GS) and peptic ulcer (PU) patients with and without IM. Data were analyzed using the Mann-Whitney U test. ^aP < 0.05 and ^bP < 0.001.
