FIG. 6.

Flow cytometric analysis of H. pylori-infected GK/2.43 mice. Flow cytometry was used to analyze the gastric lymphocyte populations in GK/2.43 and C57BL/6 mice 13 weeks after H. pylori infection. (a) Forward- and side-scatter (FSC and SSC) profiles of stomach cell preparations with lymphocytes within the gate (n = 6 for each group). Numbers within plots refer to mean percentages of cells ± SD for infected animals, and percentages of cells in pooled naive animals, within the gate or quadrant. (b) B (CD19⁺) and T (CD3⁺) lymphocytes in infected and naive GK/2.43 and C57BL/6 mice. (c) CD4⁺ and CD8⁺ cell populations within CD3⁺ lymphocytes in infected and naive animals.
