TLR4 deficiency reduces MMP9 but not MMP2 activity after UUO. (A and B) Quantification of latent and active MMP2 (A) and MMP9 (B) in obstructed kidneys of WT (□) and TLR4−/− (■) mice after UUO. No differences are observed in the renal levels of latent or active MMP2 between WT and TLR4−/− mice. The levels of latent and active MMP9 are significantly lower in the kidneys of TLR4−/− mice 14 days after UUO. Data are means ± SEM of seven mice per group. *P < 0.05.
