Abstract
- Rheumatoid arthritis (RA) is a debilitating autoimmune disease resulting from autoantibodies that cause damage to synovial joints. Joint damage causes increased systemic inflammatory cytokines which may lead to aberrant hematopoiesis. Indeed, RA is accompanied by many hematological complications including anemia, cytopenias, and suppressed bone marrow function. Hematopoietic stem cells (HSC) at root of the blood system can respond to inflammatory signals by activating the cell cycle and preferentially generating myeloid cells. However, chronic inflammation can also lead to HSC dysfunction. Previous studies using genetic mouse models of RA have identified myeloid overproduction in this context; however, HSC long-term reconstitution activity was maintained.
