Iba1 immunolabeling in spinal cord ventral horn. Normal immunolabeling for Iba1 on the side contralateral to the lesion (A). Avulsed side (B) showing a marked increase in Iba-1 labeling, which was comparable in both lesioned and EAE-induced groups (C and D). (E) Graph representing quantification of immunolabeling for all groups. (ipsi and contralateral sides shown separately) (* = p < 0.05). Scale bar = 50 μm.
