Isolated immune cells were stained with the Live/Dead Fixable Blue Dead Cell Stain Kit from Life Technologies (Grand Island, NY, USA) to exclude dead cells. Anti-mouse CD16/CD32 mAb from BD Biosciences (San Jose, CA, USA) was used to block non-specific Fc receptor binding and incubated for 20 min at 4 °C. Cells were immunostained for 30 min at 4 °C with surface antibodies (Table 1), fixed and permeabilized with BD Biosciences Cytofix Cytoperm Plus according to the manufacturer’s protocol, and stained for intracellular CD68 for 30 min at 4 °C (Table 1). Data were acquired on a BD Biosciences LSR II instrument and analyzed using the FlowJo v10.1 software (Ashland, OR, USA).
