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. WebObjective: To investigate whether citrullinated proteins within the atherosclerotic plaque can be targeted by anti-citrullinated protein antibodies (ACPAs), forming stimulatory …
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 ...
