Representative flow cytometric analyses for PBMCs. Normal (a), smoker (b), moderate COPD (COPD-M) (c), and severe COPD (COPD-S) (d) were stained for expression of CD14 and CD16. Based on staining intensity, classical monocytes (CD14 + CD16-), intermediate monocytes (CD14 + CD16+), and non-classical monocytes (CD14DIMCD16+), as well as the total numbers of monocytes were identified
