摘要: Despite the notion that human CD8+ T cells are the final mediators of autoimmune β-cell destruction in type 1 diabetes (TID), none of their target epitopes has been demonstrated to be naturally processed and presented by β cells. The inventors therefore performed an epitope discovery study combining HLA Class I peptidomics and transcriptomics strategies. Inflammatory cytokines increased β-cell peptide presentation in vitro, paralleling upregulation of HLA Class I expression. Peptide sources included known β-cell antigens and several insulin granule proteins. Secretogranin V (SCG5/7B2) was identified as a novel β-cell antigen, which was processed into HLA-A2- and HLA-A3-restricted epitopes recognized by circulating naïve CD8+ T cells in type 1 diabetic and healthy donors. HLA-A2-bound neo-epitopes were also represented and originated from an alternative SCG5-009 mRNA splice isoform. Accordingly, the present invention relates to antigenic peptides derived from secretogranin V and uses thereof for the diagnosis and treatment of T1D.

摘要: The present invention relates to methods for testing T cell priming efficacy in a subject. In particular the present invention relates to an in vitro method for testing T cell priming efficacy in a subject comprising the steps of a) providing sample from the subject, b) culturing the sample in a medium which induces the differentiation of dendritic cells, c) maturing the dendritic cells obtained at step a) in presence of an amount of at least one antigen and an amount of at least one cytokine or ligand suitable for the activation of a pathogen recognition receptor, d) priming and expanding the T cells present in the sample and e) analyzing the func tionality of the primed T cells.
