TLR4 and infection: At 15 months post infection, strong positive correlation was revealed when parasite densities were correlated with FoxP3 transcription in both liver and skin (rs = 0.821, p = 0.023 and rs = 0.860, p = 0.019, respectively) and also TLR4 transcription in the lymph node (rs = 0.821, p = 0.023).
