    OBJECTIVE: The aim of this study was to assess the extent and mechanism of activin A leading to progressive joint destruction in experimental arthritis and which cell types expressing activin A are important for disease progressio.


    Methods: Levels of activin A in synovial tissue were assessed by immunohistochemistry, cell-specific expression and secretion by PCR and ELISA, respectivel.


    Results: In this study, researchers demonstrated that fibroblast-like synoviocytes (FLS) are the major producers of activin A in arthritic joint.


    Conclusions: The results highly suggest that FLS-produced activin A plays a crucial paracrine role in inflammatory joint destruction and may be useful in the treatment of inflammatory diseases (such as rheumatoid arthritis) associated with OC formation and bone destructio.
