The distribution of a newly described peptide, neuropeptide Y (NPY) within the human spinal cord has been determined using radioimmunoassay and immunoccytochemistry. Higher concentrations were found in the lunar (49.9 ± 6.8 pmol/g) and sacral (47.0 ± 10.6 pmol/g) regions than in the cervical (27.6 ± 2.7 pmol/g) and thoracic spinal cord (33.8 |+- 5.3 pmol/g). Immunocytochemistry revealed numerous nerve fibers containing NPY in the spinal cord; these were particularly concentrated in the substantia gelatinosa of the dorsal horn. In the ventral spinal cord NPY-containing nerves were sparse becoming more abundant in lumbosacral segments.
