Brief Summary:
To investigate the effect of CTLA4-Ig (abatacept) on phenotype, transcriptional profile, B cell receptor usage and functional parameters of circulating B cells expressing anticitrullinated protein antibodies (ACPA) in patients with early, methotrexate-naïve, ACPA positive rheumatoid arthritis.
Detailed Description:
B cells expressing anti citrullinated protein antibodies (ACPA) in patients with rheumatoid arthritis (RA) display an activated, proliferative phenotype. Experimental data indicate that ACPA and ACPA-expressing B cells are actively involved in driving the disease process in RA. The present study is based on the hypothesis that targeted intervention with CTLA4-Ig (abatacept) as a means to interfere with T cell help for B cells in early, active, ACPA-positive rheumatoid arthritis can reverse the activated, proliferative phenotype of citrullinated antigen-specific B cells.
