Résumé :

Synenkephalin, which comprises 70 residues at the aminoterminal of proenkephalin, was studied with immunocytochemical methods in the human and bovine spinal cord. Immunoreactive fibers had the same general distribution as methionine-enkephalin, but not as leucine-enkephalin fibers. They were found in all spinal layers and were most numerous in lamina II (outer zone) and V-VI (lateral portion). Synenkephalin immunoreactivity was overall less dense than that of the enkephalins. These results suggest that proenkephalin is the precursor protein also in enkephalinergic neurons of the human spinal cord.
