FIG. 5.

Binding of IgG immunoglobulins to ventral horn neurons. (A) Immunostaining for rat IgG and NF200 at 2 weeks post–cervical spinal cord injury (cSCI). The ventral horn is located within the area indicated by the dashed line. IgG co-localized with NF200 in the gray but not in the white matter at the injury epicenter. In the gray matter, neuronal cell bodies of large (arrows) and smaller (arrowheads) neurons stained positive for IgG. Scale bar: 50 μm. (B) Confocal image of IgG+ neurons in the ventral horn. Scale bar: 10 μm. Color image is available online at www.liebertpub.com/neu
