Involvement in diseaseGenetic variations in IRF5 are associated with susceptibility to inflammatory bowel disease type 14 (IBD14) [MIM:612245]. IBD14 is a chronic, relapsing inflammation of the gastrointestinal tract with a complex etiology. It is subdivided into Crohn disease and ulcerative colitis phenotypes. Crohn disease may affect any part of the gastrointestinal tract from the mouth to the anus, but most frequently it involves the terminal ileum and colon. Bowel inflammation is transmural and discontinuous; it may contain granulomas or be associated with intestinal or perianal fistulas. In contrast, in ulcerative colitis, the inflammation is continuous and limited to rectal and colonic mucosal layers; fistulas and granulomas are not observed. Both diseases include extraintestinal inflammation of the skin, eyes, or joints.
Genetic variations in IRF5 are associated with susceptibility to systemic lupus erythematosus type 10 (SLEB10) [MIM:612251]. Systemic lupus erythematosus (SLE) is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system.
Genetic variations in IRF5 are a cause of susceptibility to rheumatoid arthritis (RA) [MIM:180300]. It is a systemic inflammatory disease with autoimmune features and a complex genetic component. It primarily affects the joints and is characterized by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. -

CHIPseq - Anti-IRF5 antibody - ChIP Grade (ab21689)Image from Saliba DG et al., Cell Rep. 2014;8(5):1308-17. Fig 5(A).; doi: 10.1016/j.celrep.2014.07.034.GM-BMDMs from RelAFl/Fl mice were infected with either Cre (black bars) or Empty (white bars) adenovirus and stimulated with LPS (100ng/ml) for 2 hr or left unstimulated and used in ChIP analysis for IRF5 recruitment on Il-6 and Il-1a loci. Nuclear lysates were immunoprecipitated with 10µg of ab21689. Data indicate mean percent input relative to genomic DNA ± SD of a representative experiment.
