Intraperitoneal injection of CD83 siRNA at 0.5 μmol/mouse (12.32 ± 5.67% vs. 24.5 ± 3.19%, p = 0.006) and 1 μmol/mouse (8.38 ± 4.95% vs. 24.5 ± 3.19%, p = 0.0004) to BD mice significantly decreased the frequencies of CD83+ cells in peritoneal macrophages, compared with injection with scramble siRNA (Figure 3(f)). The gene discussed is CD83; the disease is Behcet disease.
