Flow-cytometric analysis of at least 105 cells per sample was performed using a BD LSR II Flow Cytometer (BD Biosciences) following protocol as described in Dolgachev et al (2012) (link)17 and using the following antibodies Gr-1-PE,CD11c-APC-Cy7, F4/80-AF488, CD11b-PE-Cy7, CD206-APC, phospho-STAT1 and phospho-STAT6 (BioLegend and BD Biosciences, San Jose, CA, USA). Obtained data were plotted and analyzed using the FlowJo software (Tree Star, Inc., Ashland, OR, USA).
