WebThe Abatacept versus Adalimumab Comparison in Biologic-Naïve RA Subjects with Background Methotrexate (AMPLE) trial was a head-to-head, randomized study comparing abatacept in serum anti-citrullinated protein antibody (ACPA)-positive patients, with increasing efficacy across ACPA quartile levels. WebCitrulline is a post-translational modification of the amino acid arginine that results from deamidation. This chemical reaction is catalyzed by the enzyme peptidylarginine deiminase (PAD) and may occur in the setting of inflammation; the function of this modification is …

WebStudies in mice suggest that anti-citrullinated protein antibodies (ACPAs) can trigger osteoclast activation and bone resorption in the bone marrow. However, data on the presence and role of ACPAs in human bone marrow are scarce. We investigated whether ACPAs can contribute to osteoclast activation and bone erosion in RA bone marrow.

Intriguingly, they also are present on bacteria, including those in the mouth. Because of this bacterial connection, the researchers looked in the blood for a specific set of antibodies known as ACPAs, short for anti-citrullinated protein antibodies.
WebCitrullinated protein antigens are the dominant targets of the autoimmune response in RA [94]. The presence of antibodies to citrullinated proteins is detected by anticyclic citrullinated peptide (CCP) assays. These constitute a powerful diagnostic tool for RA, surpassing in both sensitivity and specificity the rheumatoid factor [95]. A key ...
