CD1d1–αGalCer tetramers stained CD1d1-restricted Vα14-Jα281 NKT cells in vivo. (A) Spleen cells from wild-type, CD1d-deficient, or Vα14-Jα281 TCR α chain transgenic mice in a C57BL/6 background were stained with CD1d1–αGalCer tetramers-PE, CD5-Cychrome, and anti–I-Ab–FITC. Dot plots were gated on MHC class II− splenocytes. (B) Splenocytes from normal mice and Vα14-Jα281 TCR α chain transgenics were stained with tetramer-Cychrome, CD5-APC, and anti-CD4 or CD8-FITC. Histograms display the frequency of CD4+ and/or CD8+ cells among gated CD5+ tetramer+ splenocytes.
