FIG. 6.
(A) Cytokine production of human mo-DCs after exposure to a range of the same K. pneumoniae wild-type strain. K. pneumoniae induced dose-dependent production of IL-12, TNF-α, and IL-10. The production of IL-12 and TNF-α, pro-Th1 cytokines, was much higher than that of IL-10. (B) Differential profiles of human mo-DC cytokine production after exposure to 1 × 105 CFU/ml K. pneumoniae wild-type strain or its derived isogenic mutants. The data presented correspond to the means and standard deviations of four independent experiments.
