How MHC molecules grab citrullinated peptides to foster rheumatoid arthritis.

ABSTRACT: The molecular immunologist's dream is to elucidate a fundamental biochemical process that explains the basis of an affliction that affects millions of people, and that, precisely understood, might yield a rational approach to diagnosis, prevention, or therapy. In this issue of JBC, Ting et al. report proteomic, biochemical, and structural analyses that better explain how the antigen-presenting HLA-DR4 molecules bind citrullinated peptides to provoke rheumatoid arthritis (RA), a chronic autoimmune disease that affects 0.5-1% of the population.
