BMDCs stimulated for 24 h with <i>H.</i><i>pylori</i> antigen were collected for flow cytometry analysis to determine (A) MHC-II expression and (B) PD-L1 expression compared to cells in media alone and isotype controls.

<p>Graphical representation of mean ± SD from data collected from three individual experiments performed in duplicate is shown on the right. Graphical representation of surface expression (C) CD86 and (D) CD40 determined by flow cytometry analysis *, <i>P</i><0.05; **, <i>P</i><0.01.
