Involvement of MD-2 expression in response to H. pylori infection in AGS cells. AGS cells were infected with H. pylori at various MOIs from 0 to 400 for 6 h (A) or at an MOI of 100 for the indicated times (B). Expression levels of MD-2 were determined by Western blot analysis. Protein expression levels were quantified using densitometric analysis, normalized to the β-actin level, and presented as means ± standard deviations for 3 independent experiments. Statistical significance was determined using Student's t test (*, P < 0.05).
