Abstract: This invention provides methods of diagnosing or predicting susceptibility to Crohn's Disease by determining the presence or absence of genetic variants. In one embodiment, the present invention provides methods to diagnose and/or predict susceptibility to Crohn's Disease in an individual by determining the presence or absence of anti-Cbir1 reactivity and the presence or absence of TLR5 risk variants. In another embodiment, the present invention provides methods to diagnose Crohn's Disease by determining the presence or absence of NFKB1 haplotype H3 and/or ASCA expression. In another embodiment, the present invention provides methods of diagnosing Crohn's Disease by determining the presence or absence of Cbir1 specific peripheral blood T cell proliferation.

Abstract: Compositions and methods for the therapy and diagnosis of immune-mediated inflammatory diseases, including inflammatory bowel disease (IBD), Crohn's disease and ulcerative colitis, are disclosed. Illustrative compositions comprise one or more bacterial polypeptides, immunogenic portions thereof, polynucleotides that encode such polypeptides, antigen presenting cell that expresses such polypeptides, and T cells that are specific for cells expressing such polypeptides. The disclosed compositions are useful, for example, in the diagnosis, prevention or treatment of immune-mediated inflammatory disease.
