Figure 7From: Type three secretion system-mediated escape of Burkholderia pseudomallei into the host cytosol is critical for the activation of NFκB B. pseudomallei wildtype but not the T3SS3 mutant induces p65, IκBα and TAK1 phosphorylation. A) HEK293T cells were infected with B. pseudomallei strains at MOI 50:1. Cells were lysed at 2 and 3 hr and analyzed by Western blot with anti-phospho-p65, anti-p65 and anti-β-actin antibodies. B) HEK293T cells were infected with B. pseudomallei and B. thailandensis strains at MOI 50:1. Cells were lysed at 2 hr and analyzed by Western blot with anti-phospho-IκBα and anti-IκBα antibodies. C) HEK293T cells infected with KHW at MOI 50:1. Cells were lysed at 1, 2 and 3 hr. Lysates were immunoprecipitated with anti-TAK1 antibody and immunoblotted with phospho-TAK1 antibody. The TNFα stimulated cells were used as a positive control. D) HEK293T cells were infected with B. pseudomallei and B. thailandensis strains at MOI 50:1. Cells were lysed at 2 hr. Lysates were immunoprecipitated with anti-TAK1 antibody and immunoblotted with phospho-TAK1 antibody. The TNFα stimulated cells were used as a positive control.Back to article page
