Four to six mice per group with average clinical EAE were examined. Mice were treated with CD200Fc versus control IgG2a from day 10. At day 15 or 30, the treated animals were killed, and flow cytometric analysis was performed for spleenocytes or cells isolated from spinal cord homogenates. All molecule expression was analyzed with gating on live cells. Data are presented as means ± SD. Statistical comparison was made using two-tailed t test.
