Figure 9From: TLR9-induced interferon β is associated with protection from gammaherpesvirus-induced exacerbation of lung fibrosisCpG oligodeoxynucleotides (ODN) stimulation lessens bleomycin-induced fibrosis. (A) C57Bl/6 male mice were injected with 0.25U bleomycin intrathecally on day 0. (B) On day 14, 50 μg CpG ODN was administered intranasally, and lung collagen was measured by hyroxyproline on day 28. (C) Lung sections were stained with Masson's trichrome to detect blue coloration indicative of collagen (n = 5 mice/group).Back to article page
