title: Antigen processing: HLA-DO--a hitchhiking inhibitor of HLA-DM.
abstract: Recent studies have revealed that the conserved major histocompatibility complex class II molecule, HLA-DO, inhibits the class II antigen-processing pathway. HLA-DO, expressed in only a subset of antigen-presenting cells, binds HLA-DM and blocks HLA-DM-catalyzed peptide loading of class II molecules.
