Expression of CD86 and MHC-II by gastric macrophages and DCs.

<p>(A) Filled histograms show expression of CD86 and MHC-II by gastric macrophages (Gr1⁻CD11b⁺CD103⁻Siglec-F⁻MHC-II⁺) and CD103⁺ DCs (CD11c⁺CD103⁺) from a naïve mouse. Open histograms show staining with isotype controls. (B) Expression of CD86 and MHC-II by gastric macrophages and CD103⁺ DCs at the indicated time points after <i>H. pylori</i> infection as determined by flow cytometry. The geometric mean fluorescence intensity of CD86 and MHC-II was normalized to the level in age-matched uninfected mice. Data represent mean ± SEM of 10–16 individual mice.
