Figure Lengend Snippet: Fig. 1 IL-37 treatment ameliorated EAE at both priming and ongoing phases. (A) C57BL/6 mice were immunized to induce EAE and treated i.p. with IL-37 (1 µg/ dose; n = 5) and PBS (n = 4) at days 1, 4, and 7 p.i. The clinical scores were evaluated daily for 21 days p.i. Mean clinical scores for IL-37-treated and PBS-treated groups were calculated as the sum of daily scores for each mouse divided by the number of days per group. (B-C) EAE mice were treated i.p. with 1 µg of rhIL-37b/ day when they showed the first symptoms of EAE. PBS was administered i.p. to the control group in the same way. Clinical scores were followed for 20 days p.i. (peak; n = 7 per group) (B) and 26 days p.i. (chronic; n = 4 per group) (C), and mean clinical scores were compared between IL-37-treated mice and control. Clinical scores were analyzed by multiple unpaired t-tests. Mean clinical scores were analyzed by Student’s t-test. Data shown as mean ± SEM. Values of p < 0.05 (*), p < 0.01 (**) and p < 0.001 (***) were considered significant. Ns: not significant

Figure Lengend Snippet: Fig. 2 IL-37 enhanced MBP expression. (A) The lumbar section of the spinal cord was harvested from EAE mice treated with PBS (left) or rhIL-37b (middle) at the peak of disease (n = 4 mice in each group). Naïve mice (right) are illustrated as a control to show healthy spinal cord. (B) Mean fluorescent inten sity of MBP expression in both groups was measured using FIJI software. Unpaired t-test was performed to analyze these two groups. Data shown as mean ± SEM. Values of p < 0.05 (*), p < 0.01 (**) and p < 0.001 (***) were considered significant. Ns: not significant
