KembaraXtra - Medical Terms - ACPA (anticitrullinated protein antibodies)
ACPA stands for anticitrullinated protein antibodies, which are autoantibodies directed against proteins that have undergone a biochemical change called citrullination. In this process, the amino acid arginine in a protein is converted into citrulline, creating a modified protein that may be recognized as foreign by the immune system.
These antibodies are highly specific for rheumatoid arthritis and are often used as a diagnostic marker for the disease. ACPA can sometimes be detected in the blood years before the clinical symptoms of rheumatoid arthritis appear. Their presence is therefore valuable for early diagnosis and may help doctors assess the likelihood and potential severity of the disease.
