Figure Lengend Snippet: Knockdown of IRF8 alleviates lung injury in COPD mice. COPD model mice were intratracheally administered with corresponding adeno-associated virus to interfere with IRF8 expression. ( A ) Lung index calculated as lung weight/body weight. ( B - E ) Assessment of emphysema in lung tissue by H&E staining. B: Representative H&E-stained images; C: Mean alveolar number; D: Mean linear intercept; E: Airway inflammation score based on inflammatory cell infiltration. ( F ) Real-time PCR analysis of IRF8 expression in lung tissue. ( G ) Western blot analysis of IRF8 protein levels in lung tissue. ( H - L ) Giemsa staining and quantification of total leukocytes ( H ), neutrophils ( I ), Eosinophil ( J ), macrophages ( K ), and lymphocytes ( L ) in bronchoalveolar lavage fluid (BALF). ( M - O ) ELISA detection of TNF-α (M), IL-1β ( N ), and IL-1α ( O ) levels in lung tissue. N = 6 replicates
Article Snippet: Recombinant adeno-associated virus (AAV) vectors were constructed and produced using the shuttle plasmid pAV-U6-shRNA-CMV-RFP (Vigene Biosciences, pAV100004-KD).
