Figure 5: Constitutive and IL-7 induced STAT-5 phosphorylation. Percentage of STAT-5 phosphorylation in response to IL-7 stimulation in BCG- , rBCG-vacinated and control animals. Vaccination and Mtb infection did not impact on constitutive or IL-7-induced STAT-5 phosphorylation. Animals that showed an increase or decreased IL-7Rα expression after Mtb infection are marked with an arrow.
