CD4+ T cells were collected and re-stimulated for 4 h with phorbol 12-myristate 13-acetate (PMA) (50 ng/ml; Sigma) and ionomycin (750 ng/ml; Calbiochem, La Jolla, CA, USA) with GolgiStop (BD Biosciences). Cells were stained with anti-mouse CD4-FITC (GK1.5; BioLegend, San Diego, CA, USA), anti-mouse B220-PE/Cy7 (RA3-6B2; BioLegend), anti-mouse CD3 ε-APC (145-2C11; BioLegend), anti-mouse CD8a-PE/Cy7 (53-6.7; BioLegend), anti-mouse IFN- γ-PE (XMG1.2; BioLegend), and anti-mouse IL-17A-APC (TC11-18H10.1; BioLegend) according to the manufacturer’s instructions. Data were obtained with a FACSVerse (BD Immunocytometry System, San Jose, CA, USA) and analyzed using FlowJo software.
