Figure 4. Helicobacter pylori cagPAI+ strains and a cagPAI– strain did not induce changes in TLR4 expression.

Figure 4

Mean fluorescence intensity (MIF) of TLR4 on neutrophils 3, 6, and 24 h after infection (A, B, and C, respectively) with cagPAI+ strain 26695, T4SS mutants (virB4– and virD4–), or cagPAI– strain 8822. The data shown are from three independent experiments and line represent median. Flow cytometry results were obtained as medians ± intervals of percentiles and analyzed with the Kruskal–Wallis one-way test. Differences were considered statistically significant when*P<0.05. MC = mock control.
