title: HLA-B27 and HLA-B73 polymorphism and its role on antigenicity, peptide presentation, and disease susceptibility.
abstract: Current ideas on the structure, evolution, and disease association of HLA-B27 antigens are presented, with emphasis on the effect of HLA-B27 polymorphism on T-cell recognition and antigen-presenting properties of these molecules. The molecular relationship between HLA-B27 and HLA-B73, and its implications for a putative pathogenetic role of the later antigen are discussed.
