Although, two major isoforms of sulfatide, C16:0 and C24:0, are enriched in the pancreas, their relative role in autoimmune diabetes is not known. Here, we report that sulfatide/CD1d-tetramer(+) cells accumulate in the draining pancreatic lymph nodes, and that treatment of NOD mice with sulfatide or C24:0 was more efficient than C16:0 in stimulating the NKT cell-mediated transfer of a delay in onset from T1D into NOD.Scid recipients. Using NOD.CD1d(-/-) mice, we show that this delay of T1D is CD1d-dependent. Interestingly, the latter delay or protection from T1D is associated with the enhanced secretion of IL-10 rather than IFN-g by C24:0-treated CD4(+) T cells and the deviation of the islet-reactive diabetogenic T cell response. Both C16:0 and C24:0 sulfatide isoforms are unable to activate and expand type I iNKT cells. Collectively, these data suggest that C24:0 stimulated type II NKT cells may regulate protection from T1D by activating DCs to secrete IL-10 and suppress the activation and expansion of type I iNKT cells and diabetogenic T cells. Our results raise the possibility that C24:0 may be used therapeutically to delay the onset and protect from T1D in humans.", "link"=>"http://www.mendeley.com/research/nkt-cells-stimulated-long-fatty-acyl-chain-sulfatides-significantly-reduces-incidence-type-1-diabete-1", "reader_count"=>20, "reader_count_by_academic_status"=>{"Researcher"=>6, "Student > Ph.

(<b>C</b>, <b>D</b>) Treatment with sulfatide inhibits the induced anti-islet diabetogenic T cell cytokine responses. Female NOD mice (4 week-old, 4 mice/group) were injected i.p. with sulfatide (20 mg/mouse) or vehicle/PBS. One week later, the treated mice were immunized with 100 mg of either the insulin p9–23, GAD206-220, GAD524-543 or hsp277 peptide. Ten days following antigenic challenge, PLN lymphocytes were assayed for their proliferative ([<sup>3</sup>H]-thymidine incorporation) and cytokine (IFN-g, IL-4) secretion responses (Elispot assay). The average frequencies of IFN-γ (<b>C</b>) or IL-4 (<b>D</b>) secreting cells reactive to different islet antigens are shown. In comparison to control vehicle values, statistically significant reductions in the frequencies of cytokine-secreting islet antigen-reactive T cells were found for the insulin and GAD peptides but not Hsp peptide, as follows. Insulin 9–23 (P = 0.0001 for IFN-g, P = 0.0078 for IL-4); GAD 206-220 (P = 0.012 for IFN-g, P = 0.0018 for IL-4); GAD 524-543 (P<0.0001 for IFN-g, P = 0.0328 for IL-4); and Hsp 277 (Not significant, P = 0.0542 for IFN-g; Not significant, P = 0.0952 for IL-4).</p>", "links"=>[], "tags"=>["cytokine", "secretion", "responses", "induced"], "article_id"=>304555, "categories"=>["Chemistry", "Biochemistry", "Immunology"], "users"=>["Lakshmimathy Subramanian", "Hartley Blumenfeld", "Robert Tohn", "Dalam Ly", "Carlos Aguilera", "Igor Maricic", "Jan-Eric Månsson", "Karsten Buschard", "Vipin Kumar", "Terry L.
