SortA-CD1d and SortA-TD-CD1d can load lipid antigens and present them to NKT cells. L cells stably transfected with SortA-CD1d or SortA-TD-CD1d were loaded with (A) αGalCer, (B) αGalGalCer or (C) C20:2 and were subsequently co-cultured with NKT hybridoma cells. IL-2 concentration as a measure of NKT cell activation was determined by ELISA in cell culture supernatants. Graphs show mean ± SD of biological duplicates and are representative for one out of at least two independent experiments.
