M2 immune response after UUO in WT, TLR2, TLR4 and MyD88 KO animals. Percentage of T CD4+ cells expressing IL-4 (A) and IFN-γ (B) in WT, TLR2, TLR4 and MyD88 KO animals 7 d after UUO. IL-4:IFN-γ ratio in TLR2, TLR4, and MyD88 KO mice (C). The ratio of WT mice subjected to UUO was considered 1. Percentage of infiltrating CD11bhigh (D) and CD11blow cells (E) and percentage of CD11bhigh cells expressing CCR7(F), CD206(G), IL-10(H), IL-12 (p40) (I) and MIG (J) in WT, TLR2, TLR4 and MyD88 KO animals 7 d after UUO. Dashed line represents WT animals not submitted to UUO. *p < 0.05.
