Figure Lengend Snippet: Figure 5. Role of TLR9 and IL-12 (p70) in Treg Conversion (A and B) Groups of C57BL/6 and TLR-deficient mice infected with LD or HD Lm DactA-Ova. (A) Absolute number of Ova-specific CD8+ T cells at day 7 post-infection with HD Lm DactA-Ova compared among splenic isolates of Tlr2/, Tlr4/, Tlr7/, and Tlr9M7Btlr mice (n = 6–10 per group). (B) Absolute number of Ova-specific CD8+ T cells at day 7 in the spleens of Tlr9M7Btlr mice ± CD4+ T cell depletion (n = 6–8 per group). (C and D) Groups of C57BL/6 and Tlr9M7Btlr mice systemically infected with HD Lm DactA-Ova. (C) Fold change in serum cytokines and chemokines from 0–6 h post-infection. (D) Selected serum cytokine/chemokine concentration at 6 h post-infection displaying significance in (C) (n = 6 per group). (legend continued on next page)
