Figure 1. Spinal nerve ligation (SNL) induces a substantial upregulation of CX3CR1 in spinal cord microglial cells.
(a) Upregulation of CX3CR1 in the ipsilateral side of the spinal cord (L5), 3 days after ligation of the L5 spinal nerve. (b–d) Double staining reveals a complete co-localization of CX3CR1 with the microglial marker OX-42 in the dorsal horn. Scales, 100 μm.
