Fig. 1From: Toll-like receptor 9 partially regulates lung inflammation induced following exposure to chicken barn airBAL cell counts. BAL from exposed and unexposed WT and TLR9-deficient (TLR9-) mice (n = 6) was spun briefly at 400 g, supernatant removed, and cells resuspended to 100 μl for counting with hemocytometer. BAL cell numbers were lower in TLR9−/− mice compared to WT mice after 20 exposures (* = p ≤ 0.05)Back to article page
