Type B synovial cells play a key role in the pathogenesis of chronic inflammatory diseases, such as rheumatoid arthritis, and are essential for the maintenance of normal joint functions. Fibroblast-like synoviocytes from different joints have different properties, which may contribute to the characteristic pattern of joint involvement in different types of arthritis.
