Figure 3. HMGB1 expression in rat lungs.
(A) qPCR and (B) ELISA analysis were performed to determine respectively mRNA and protein expression of HMGB1 in lung tissues of rat pups infected with rrRSV at 10 d of life and killed 5 d later. Both HMGB1 mRNA and protein increased significantly in the lungs of rrRSV-infected rats compared to pathogen-free controls. (C) Increased HMGB1 protein expression in rrRSV-infected rat lungs was confirmed by Western blot. (D) Densitometry analysis. Data are expressed as mean ± SEM. **P<0.01, ***P<0.001 compared to non-infected cells. All experiments were repeated at least three times.
