 Altered expression of adhesive and chemokine receptors induced by PM_ap. THP-1 cells (a) or primary monocytes (b) were incubated with vehicle control or PM_ap (ratio per cell, 10/1), basically as described for Figure 2. After 44 h or 7 days of incubation, expression levels (FI) of the adhesive GPs, CD11b, CD14 and CD31, and of the chemokine receptors, CCR2, CCR5 and CXCR4 were determined by flow cytometry. Mean±S.E.M. (n=4–7). ^*P<0.05 versus control
