The effects of peripheral axotomy (sciatic nerve transection) on the presence and distribution of neuropeptide Y (NPY) in rat dorsal root ganglion (DRG) and spinal grey matter were examined using immunocytochemistry. In normal rats and on the sham-operated side of experimental rats, NPY-like immunoreactivity (NPYir) was observed in all laminae of the lumbar spinal cord, with an especially dense concentration of immunostained axons and axonal varicosities in laminae I-II of the dorsal horn… CONTINUE READING
