Detection of autoantibodies against mutated citrullinated vimentin is part of rheumatoid arthritis (RA) diagnostics, especially in sera negative for rheumatoid factor (RF negative sera). Anti-MCV antibodies are a member of the ACPA family, a group of the so-called antibodies to citrullinated protein/peptide antigens. Rheumatoid arthritis is an autoimmune disorder. Detection of specific autoantibodies (antibodies directed against the body’s own tissue) such as rheumatoid factors and ACPAs may provide indication of the disease. In many cases, autoimmune diagnostics are crucial for diagnosing RA correctly and already in the disease’s early stages, when typical symptoms often are lacking but when medical therapy is most effective. == Basics== Citrullination is a modification of proteins where a nitrogen in the amino acid arginine is replaced with an oxygen, converting it into citrulline. The modified (citrullinated) protein may be identified by as foreign, provoking an autoimmune inflammation response. Various kinds of citrullinated proteins have been detected in the joints of RA patients. One of these is Sa antigen, now known as mutated citrullinated vimentin (MCV). Citrullination of vimentin plays a decisive role in RA pathogenesis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mutated citrullinated vimentin」の詳細全文を読む スポンサード リンク
