Selection and maturation of iNKT cells is compromised in the thymus of Sandhoff and GM1 gangliosidosis mice. Four-color flow cytometry was performed on thymocytes from Sandhoff, GM1 gangliosidosis, and age-matched control mice. Cells were stained with NK1.1 and CD44 antibodies, a pan–TCR Vβ antibody, and an α-GalCer/CD1d tetramer. The maturation phenotype was analyzed by gating on CD3+/tetramer+ cells. (A) The percentage of thymic iNKT cells of the immature CD44/NK1.1, semimature CD44+/NK1.1, or mature CD44+/NK1.1+ phenotype as a percentage of α-GalCer/CD1d tetramer+/Vβ+ cells. (B) Total number of iNKT cells at three different stages of maturation (CD44/NK1.1, CD44+/NK1.1, and CD44+/NK1.1+) from homozygous Sandhoff or GM1 gangliosidosis mice and controls are shown. Data represent one of two independent experiments (mean ± SE; n = 3–5 mice/group).
