Flow-cytometry analysis of Thp1 cells. (a) Fraction of cells with phagocytosed fluorescent microspheres. P-values for the stimulation with HcpA and PMA are 2.6·10−3 and 1.0·10−3, respectively. (b) Mean fluorescence intensity of cells stained with a fluorescent anti-CD11b antibody. P-values for the stimulation with HcpA and PMA are 4.1·10−4 and 5.0·10−4, respectively.
