Disease ... Joint histopathology data supports the preclinical arthritis score. As shown in the representative H&E staining, both untreated control CIA mice and CIA mice treated with MTX alone showed significant joint infiltration by leukocytes and severe disruption and loss of articular cartilage (Figure 2(b)). The CIA group treated with smDCs alone or in combination with MTX (0.5?mg/kg) showed nearly intact articular cartilage and subchondral bone and less synovial hyperplasia in the histopathologic analysis (Figure 2(b)). Interestingly, treatment with smDCs alone was also as effective as combination therapy with 0.5?mg/kg MTX in controlling disease progression of CIA mice, but the combination of 0.1?mg/kg MTX + smDCs did not show any therapeutic effect (Figures 2(a) and 2(b)). These data suggest that RA patients taking MTX can be treated with smDC vaccines without disturbing MTX treatment because MTX is a standard therapy for early RA patients. 3.3. Antiarthritic Effects of smDCs or Combination Therapy with MTX Were Associated with Long-Term Immune Hyporesponsiveness Since it was reported that T cells play an important role in CIA onset [24] and smDCs can induce immune tolerance by T cell hyporesponsiveness [25], we evaluated Sitaxentan CII-specific T cells by proliferation assay with splenic T cells from each group of mice. In comparison with an untreated control group of CIA mice, CII-specific T cell proliferation was significantly decreased in mice treated with smDCs alone or in combination with 0.5?mg/kg MTX (Figure 3(a)). These data suggest that the preclinical implications shown in Figure 2 would be associated with CII-specific T cell hyporesponsiveness after the treatment of CIA mice with smDCs alone or in combination with MTX. Treatment with MTX (0.5?mg/kg) alone also reduced CII-specific T cell proliferation to some amount in CIA mice (Figure 3(a)), suggesting that the hyporesponsiveness induced by MTX (0.5?mg/kg) alone would not be enough to control disease progression. Figure 3 Analysis of CII-specific splenocytes and the levels of CII-specific IgG and proinflammatory cytokines in CIA mice after a combination therapy. (a) Advanced CIA mice were treated with smDCs, MTX, or smDCs and MTX. Splenocytes were isolated from mice on ... CIA mouse serum contains profound amounts of CII-antibody at the time of disease onset [26]. It has also been suggested that tolDCs are involved in the inhibition of B cell-mediated antibody production by blocking T-helper cell function [27]. In vitro generated smDCs prevent arthritis and inhibit anti-CII antibody production in CIA mice [25, 28]. We examined the level of anti-CII antibody in CIA mouse serum after treatment with smDCs.
