CX3CL1 antibody mediated blockade protects mice against EAE and its associated lymphocyte infiltration. Wild type mice were induced to develop EAE and starting at day 8 post induction given daily anti-CX3CL1 antibody or an isotype control treatments (i.p.). (A) EAE disease profile. Error bars represent the s.e.m. (n = 4 mice/group). Significant differences are indicated as determined by two-way ANOVA. EAE scoring data is representative of 2 separate experiments. (B) CD45, CD11b, and F480 stained brain (hippocampal and cerebellum areas) and spinal cord sections from day 28 post-EAE induced mice treated with either anti-CX3CL1 or control antibody. Positively stained cells (red) are shown against a hematoxylin counterstain (blue). Black scale bars represent 50 μm. (C) CD4 and (D) CD8 positive mean cells counts per field at 10x magnification from brain and spinal cord stained frozen brain sections from day 28 post-EAE induced mice treated with either anti-CX3CL1 or control antibody. Error bars represent the standard error of the mean (n ≤ 11). Significant differences (P < 0.05, *) are indicated as determined by the Student’s t-test.
