CD169 and CD64 expressions after blood stimulation. Whole blood of three donors was coincubated for 7 hours at 37°C with either no activator (Non Act), or interleukins (IL‐2, IL‐6, IL‐12, IL‐18, IL‐12 + IL‐18) or infectious extracts (Poly IC, lipopolysaccharide [LPS]) or interferons (IFNα1 and IFNγ). Extracellular staining of the activated blood was performed with the CD64‐CD169/infections antibody mixture. Results are expressed as averages ± standard deviations of the median of fluorescence intensities (MFI) of CD169 on monocytes (mCD169) (A) and of CD64 on neutrophils (nCD64) (B). The comparison was made using a Dunnett's control test, with the Non‐Act condition used as control (in white) and P value was considered either not statistically significant above .05 (in gray; NS) or statistically significant under .05 (in black; *) or under .01 (in black; **). NS, not significant
