CCL3, CXCL9, and CXCL16 transcript expression by purified CD1a+ DCs. CD1a+ DCs were isolated from human lungs by immunomagnetic beads and used for RNA analysis. Chemokine transcripts for CCL3 (A), CXCL9 (B), and CXCL16 (C) are shown. Transcripts were measured by real-time PCR, and results are expressed as arbitrary units. Levels were correlated to COPD severity, as determined by GOLD stage. Correlation statistical analysis is shown.
