Abstract excerpt
Ankylosing spondylitis (AS) is an inflammatory disease strongly associated with the Major Histocompatibility Complex class I (MHC-I) allotype HLA-B*27. The endoplasmic reticulum aminopeptidases (ERAP)1 and 2, which trim peptides to their optimal length for MHC-I binding, are also susceptibility factors for this disease. Both highly active ERAP1 variants and ERAP2 expression favor AS, whereas loss-of-function...
