Modulation of Stat-1 in Human Macrophages Infected with Different Species of Intracellular Pathogenic Bacteria

Figure 3

Densitometric analysis of p-tyr₇₀₁Stat-1 expression levels in macrophages infected with Salmonella typhimurium (St) and Listeria monocytogenes (Lm). After infections, macrophages were cultured for 2 days in the absence or presence of 0.15 μg/mL of anti-IFN-gamma antibody and Stat-1 and p-tyr₇₀₁Stat-1 expression levels were evaluated by Western blot assay at the indicated times. Data were the mean of three different experiments. The differences of the p-tyr₇₀₁Stat-1 expression levels between infected and infected cells after INF-gamma blocking were not significant.
