Le purpura thrombotique thrombocytopénique (PTT) est une maladie autoimmune rare et grave caractérisée par la présence d’anticorps dirigés contre ADAMTS13 (A13), une protéase impliquée dans l’hémostase primaire. L’implication des lymphocytes T CD4⁺ spécifiques d’ADAMTS13, dans la physiopathologie de la maladie est suggérée par une restriction pour l’haplotype HLA-DRB1*11 (DR11), l’isotype IgG des anticorps. Dans ce travail, nous avons cherché à identifier les épitopes T d’A13. Tout d’abord, nous avons sélectionné in silico les peptides d’A13 susceptibles d’être présentés par les molécules HLA-DR11. Ensuite, l’étude de la liaison de ces peptides à des molécules HLA-DR11 par des tests ELISA compétitifs a permis d’identifier les peptides les p...
