(A) B6 and TCR-δ−/− mice were immunized with IRBP1-20/CFA, then, 13 days later, splenic T cells were enriched and assessed for Th1 and Th17 IRBP1-20-specific T cells by LDA. (B) Splenic T cells from immunized B6 and TCR-δ−/− mice were stimulated with IRBP1-20 and APCs under Th17 polarizing conditions for 5 days, then the activated T cells were separated, fixed, and stained with anti-IFN-γ, anti-IL-17, and anti-αβ TCR antibodies.
