✦ Synopsis
Population and peptide specificity analyses and studies in transgenic rodents support a role of HLA-B27 as an antigen-presenting molecule in spondyloarthropathy. The interplay between HLA-B27 and arthritogenic bacteria on infected cells suggests that HLA-B27 might also influence disease by other mechanisms. Recent genetic advances promise the identification of additional susceptibility genes.

The association of HLA-B27 and seronegative spondyloarthropathies, especially ankylosing spondylitis has been known for almost two decades. The spontaneous development of spondyloarthropathy like joint disease in HLA-B27 transgenic rats verifies the suspicion that the HLA-B27 antigens are directly r
## Objective: To determine whether hla-b27 positive patients with ankylosing spondylitis (as) and reactive arthritis (rea) share additional hla factors that confer disease susceptibility. ## Methods: Hla class i antigens were typed serologically, and class ii antigens molecularly, in samples take
Restriction fragment length polymorphism (RFLP) typing of MHC-class II loci DRB, DQA1, DQB1, DQA2 and DPB1 was performed in 94 patients with seronegative juvenile chronic arthritis (JCA) and 184 random controls. Analysis of allele frequencies and MHC-class II 4-loci haplotypes indicate: (1) Suscepti
