Reduced Th17/Treg and increased Th1 responses in <i>H. pylori</i>–infected TLR2KO mice.

<p>After an <i>H</i>. <i>pylori</i> (10⁹ CFU/mL) infection of 2 months duration, stomachs from WT mice and TLR2-deficient mice were removed. mRNA expression of Foxp3 (<b>a</b>), IFN-γ (<b>b</b>), IL-10 (<b>c</b>), IL-17A (<b>d</b>), TNF-α (<b>e</b>) and the housekeeping gene GAPDH were measured by quantitative PCR (n = 10 mice per group; ^*<i>P</i> < 0.05).
