This article presents the concept that Behçet disease and several spondyloarthropathies might have a common immunopathogenetic basis. The authors propose that barrier dysfunction in environmentally exposed organs, and aberrant innate immune reactions at sites of mechanical stress, trigger secondary adaptive immune CD8+T-cell responses characterized by prominent neutrophilic inflammation. The differential immunopathology of these 'MHC-I-opathies' could reflect antigenic differences in target tissues.
