2. Fig. 1
Flow cytometric analysis of PBMCs from a normal individual. Displayed in the dot plots are cells gated by forward scattering and side scattering. The cells within the box are considered positive. The number next to the box is the percentage of positively stained cells in the lymphocyte population. (A) Cells stained with FITC-labeled anti-CD3 antibody and PE-labeled hCD1d tetramer without α-GalCer. (B) Cells stained with FITC-labeled anti-CD3 antibody and PE-labeled hCD1d tetramer loaded with α-GalCer. (C) Cells stained with FITC-labeled anti-TCRαβ antibody and PE-labeled hCD1d tetramer loaded with α-GalCer. (D) Cells stained with FITC-labeled anti-TCR Vα24 antibody and PE-labeled anti-TCR Vβ11 antibody. (E) Cells stained with FITC-labeled anti-TCR Vα24 antibody and PE-labeled hCD1d tetramer loaded with α-GalCer.

4. Fig. 3
Enrichment of hCD1d tetramer-reactive cells from a normal individual. CD14 depleted PBMCs were stained with FITC-labeled anti-TCR Vα24 antibody and PE-labeled hCD1d tetramer, followed by incubation with anti-PE microbeads and magnetic separation to enrich tetramer-binding cells. Displayed in the dot plots are cells gated by forward scattering and side scattering. The number next to the box is the percentage of tetramer+ cells in the lymphocyte population. (A) Before enrichment. (B) After enrichment.

(A) Healthy donor PBMCs or (B) PBMCs cultured for 12 days with α-GalCer and recombinant human IL-2 were costained with FITC-labeled anti-TCR Vα24 antibody, PE-labeled anti-TCR Vβ11 antibody, and TC-labeled tetramer. (A) Flow cytometric analysis of fresh PBMCs from a normal individual with tetramer staining on gated PBMCs cell populations; TCR Vα24− Vβ11+ (R1) cells, TCR Vα24+ Vβ11+ (R2) cells, TCR Vα24+ Vβ11− (R3) cells, and TCR Vα24− Vβ11− (R4) cells. (B) Flow cytometric analysis of PBMCs from a normal individual after in vitro stimulation with α-GalCer and recombinant human IL-2 with tetramer staining within TCR Vα24+ Vβ11+ cells (heavy line) and TCR Vα24− Vβ11− cells (thin line) (bottom left); TCR Vα24+ Vβ11+ staining within tetramer+ cells (bottom right).

6. Fig. 5
Analysis of TCR Vα24 diversity of CD1d-αGalCer-restricted NKT cells. Fragment length analysis of the Vα 24JαQ CDR3 region is depicted following PCR amplifications with primers for Vα24 and JαQ. The intensity of the fluorescence is represented in arbitrary units as a function of CDR3 length in amino acids. Results from 3 donors are shown.

CD4 and CD8 coreceptor expression by the tetramer-reactive T cells before and after in vitro stimulation. The cells were stained with FITC-labeled anti-CD3 antibody, PE-labeled tetramer, TC-labeled anti-CD4 antibody, and APC-labeled anti-CD8 antibody. Cells gated by forward scattering and side scattering. (A) The frequency of CD4− CD8−, CD4+ CD8−, and CD4− CD8+ subpopulations within the tetramer-reactive population in the PBMC of normal individuals (n = 8). (B) The frequency of the same PBMCs after in vitro stimulation with α-GalCer and recombinant human IL-2 (n = 8).
