Histological characterization of the RA model in DA rats. Tissue slides from joints of non-treated rats (A) and joints from Mtb-treated rats (B) were analyzed at 20 days post-injection using Hematoxylin and Eosin stained sections from ankle joints (hind paw). The histological architecture shows synovial hyperplasia and infiltration of inflammatory cells. (Magnification x200).
