Finally, monocytes from AECOPD patients expressed similar amounts of CD14 (407 ± 70.76 mfi) than monocytes from never smokers (395 ± 117.2 mfi), stable COPD patients (439 ± 116.8 mfi) or smokers (422 ± 154.4 mfi) (fig 1, panel C). This evidence concerns the gene CD14 and chronic obstructive pulmonary disease.
