Figure 5. Up-regulation of NPY in nucleus gracilis after nerve injury.

Figure 5

Panel A illustrates a representative photomicrograph of NPY immunoreactivity (NPY-ir) in nucleus gracilis of a TxCPx (SNI) rat taken two weeks after nerve injury. The remaining photomicrographs depict higher power images of the ipsilateral nucleus gracilis at two weeks (A,B,D,F,H) or 24 weeks (C,E,G, I) after SHAM (B,C), TxCPx (A,D,E), Tx (F,G), or CPxSx (H,I). Panel D represents a higher magnification image of the ipsilateral dorsal horn from an SNI rat, as indicated by the box in Panel A. Panel J illustrates averaged NPY-ir for each condition. ⋆p<0.05 compared to respective Sham group. †p<0.05 compared to respective 2 wk group. n = 7. Scalebars = 250 μm.
