For immune cell profiling, ∼1,000,000 cells per mouse were stained with fluorochrome-conjugated antibodies against CD45, CD3, CD4, CD8, FOXP3, RORγt, and CD62L (eBioscience), and their populations were analyzed by a CytoFLEX (Beckman-Coulter) using software packages from CellQuest and FlowJo version 12 as described previously (35 (link)).
