Furthermore, we observed that CD4+ T cells were recruited to the stomach during infection with H. pylori. While the proportion of CD4+ T cells from the CD45+ leukocyte population was similar in mice colonized by H. pylori wt or ΔgGT, infiltration of non-CD4+ T cells - most likely CD8+ T cells - were more strongly induced by gGT-positive H. pylori (Fig. 3c). Here, CD8A is linked to infection.
