FIG 1

P. gingivalis-infected MoDCs do not express mature chemokine receptors. MoDCs were infected for 24 h with WT Pg381, fimbria-deficient DPG-3 (mfa-1+), nonfimbriated MFB, or fixed E. coli at an MOI of 1 or stimulated with a cocktail of E. coli LPS and TNF-α. Representative histogram plots are shown for each of the analyzed chemokine receptors, with percentage-based cumulative data shown in the lower part of the figure. Baseline expression of MoDCs at the time of infection is indicated with a black trace, uninfected MoDCs are indicated with a blue trace, and infected MoDCs are indicated with a green trace. Our controls of whole E. coli or DC maturation stimuli E. coli LPS and TNF-α are indicated by a red trace (panel 1). Mfa-1+ strains (WT, DPG-3) caused a more significant upregulation of CXCR4 than other treatments. E. coli LPS/TNF-α and E. coli treatment did not cause CXCR4 upregulation (panel 2). P. gingivalis did not cause significant upregulation of CCR7 as in controls (panels 3 and 4). Treatments resulted in a significant downregulation of CCR5 and CCR6. α, P < 0.05; *, P < 0.01.
