Figure 2. CD4⁺ and CD8⁺ T cell infiltrates are enhanced in TLR2 KO mice.

Abscess-associated cells were recovered from TLR2 KO and WT mice at the indicated days post-infection (n = 4 to 6 animals per group), whereupon CD3⁺CD4⁺ and CD3⁺CD8⁺ T cells were quantitated by FACS. Significant differences between TLR2 KO and WT mice are denoted with asterisks (*, p < 0.05). Results represent the mean ± SEM from 3–4 independent experiments.
