Figure 5

Pathological changes and scores of the joint. HE staining showed the pathological changes of synovial tissue in the figures of control (a), RA (b), Mox (c), PD-1+Mox (d), and PD-1+RA (e) group. Magnification, ×100. (f, g) The score of the proliferation of synovial tissue and infiltration of inflammatory cell. n = 10 for each group. Data were expressed as the mean ± SD. ; . The square represents the pathological changes of the joint.
