As shown in Figure 2, body CD4+/antrum CD4+, which is calculated by dividing CD4+/CD3+ in the lesser curvature of the body by CD4+/CD3+ in the greater curvature of the antrum, was significantly higher in autoimmune gastritis (3.54 ± 3.13) than in active (1.47 ± 0.41) and inactive gastritis (1.42 ± 0.77). The gene discussed is CD4; the disease is gastritis.
