In line with the known immunomodulatory effects of H. pylori[76], [77], [78], the expression of CD-markers related to T helper (CD4/GATA4) and regulatory T cells (CD25/FOXP3) was suppressed upon an 11-month infection with H. pylori SS1, and this phenomenon was most pronounced in Cav1-KO mice. This evidence concerns the gene GATA4 and infection.
