pooled and sorted on a BD FACS Aria (BD Biosciences). Briefly, BMDCs were
harvested, pooled, incubated with Fc receptor-blocking antibody (16-0161-86,
Thermo Fisher) for 15 minutes on ice, and the CD11c+ BMDCs were
enriched using CD11c microbeads following the manufacturer’s
instructions. To sort GM-DCs and GM-Macs, the CD11c-enriched BMDCs were
stained with antibodies against CD11c (N418, Thermo Fisher, 1:300), CD11b
(M1/70, Thermo Fisher, 1:300) MHC-II (M5/114.15.2, Thermo Fisher, 1:400),
CD115 (AFS98, Biolegend, 1:100), MerTK (DS5MMER, Thermo Fisher, 1:100), and
CD135 (A2F10, Biolegend, 1:50). GM-Macs were sorted as
CD11c+CD11bhiMHCIIlo-intCD115+MerTK+while GM-DCs were sorted as
CD11c+CD11bintMHCIIhiCD115−CD135+(see also
