Reduced capacity to process and present a lysosome-dependent analogue of α-GalCer by GSL storage APCs. Splenocytes (A, B, and E) and TNF-α–matured BMDCs (C, D, and F) from control, GM1 gangliosidosis, Sandhoff, or CD1dKO mice were pulsed for 6 h with either α-GalCer (A and C) or Gal(1→2)GalCer (B and D) and used to stimulate the DN32-D3 invariant NKT cell hybridoma (A, B, C, and D). Unpulsed splenocytes (E) and BMDCs (F) were used to stimulate the CD1d-restricted, noninvariant hybridoma TCB11 for 24 h in vitro. Supernatants were analyzed using an IL-2 ELISA. Data represent one of two independent experiments (mean ± SE; n = 2–3 mice/group).
