Lung NTPDase1/CD39 Protein Expression Divided by Groups. Analyses of total lung tissue showing the band densities of CD39 in the COPD (n = 13), NOS (n = 12), and NS (n = 12) groups. CD39 protein levels were lower in the COPD group. Data are expressed as median ± rank. Abbreviations: NTPDase1, nucleoside triphosphate diphosphohydrolase-1; COPD, Chronic obstructive pulmonary disease; NOS, Non-obstructed smokers; NS, Never smoker
