Cells used for in vitro or in vivo cytokine analysis were stimulated with PMA (20 ng/ml; Sigma-Aldrich), Ionomycin (1 µg/ml; Sigma-Aldrich), and Brefeldin A (2 µg/ml; Sigma-Aldrich) for 4 hr prior to flow staining (Lu et al., 2015 (link)). For intracellular staining, cells were fixed and permeabilized using the Mouse FOXP3 Buffer Set (BD) per the manufacturer’s protocol. The fluorophore-conjugated antibodies used in this study were as follows: Live/Dead Fix Blue (Invitrogen), CD3 PerCPCy5.5 (Biolegend), TCRb PE/Cy7 (Biolegend), CD4 PB (Biolegend), CD4 AF700 (Biolegend), CD8 BV650 (Biolegend), CD25 BV421 (Biolegend), FOXP3 AF488 (Biolegend), ROR gamma T PE (Invitrogen), TCF1 AF647 (Cell Signaling Technologies), TCF1 PE (Biolegend), IFNγ AF647 (Biolegend), IL17A FITC (Biolegend), and IL17A PE (ebioscience). Samples were analyzed using BD LSR II flow cytometer (BD Biosciences) and FlowJo software (TreeStar).
