From: Activation and polarization of circulating monocytes in severe chronic obstructive pulmonary disease
Altered composition of monocyte sub-populations in smokers and COPD patients. Classical (a, c, e, and g) and non-classical (b, d, f, h) monocytes were stained for CD163 (a, b), CD25 (c, d), CD206 (e, f), and IL-13Rα1 (g, h) expression. The data are presented as the percentage of total classical or non-classical monocytes for each group. *** = p < 0.001 are relative to the normal
