FIG. 2.

Phenotype of in vitro-expanded macaque NKT cell lines. (A) CD1d-tet-sorted macaque T cells expanded by α-GalCer (100 ng/ml) stimulation. (B) CD4⁺ macaque T cells stimulated and expanded with SEB-pulsed (100 ng/ml) DCs were stained with Vα24-fluorescein isothiocyanate and CD1d-tet-PE. (C) Macaque NKT cell lines were also stained with anti-CD4 and -CD8 antibodies. NKT cells (D) and CD4⁺ macaque T cell lines (E) were stained with anti-CCR5 or with an isotype control antibody.
