Figure 6From: CpG oligonucleotide activates Toll-like receptor 9 and causes lung inflammation in vivoLung MPO content. Content of lung MPO was documented in WT mice following application of CpG-ODN. In WT mice, MPO increased significantly 6 hrs after CpG-ODN stimulation, whereas TLR9-D mice exhibited no increase in MPO activity. Data are expressed as a % of controls (mean ± SEM; * p < 0.05).Back to article page
