abstract：:The second HLA-DR molecules, which are encoded by loci different from HLA-DRB1 are weakly polymorphic. Predominant alleles such as HLA-DRB3*0101, HLA-DRB4*0101 and HLA-DRB5*0101 are therefore interesting targets to define antigenic peptides with major impact for the entire population. Strikingly, they have been poorly...
