From: Chemokine Expression by Small Sputum Macrophages in COPD
Chemokine protein in sputum in COPD and control donors. Supernatants from induced sputum samples were assessed by ELISA for CCL2, CCL7, CCL13 and CCL22 protein. Shown are the mean values in pg protein/mL in n = 8 controls (left bars) and in n = 5 COPD patients (right bars). *P < 0.05 for all proteins.
