Quantitative autoradiographic analysis of [125I]-human CGRP binding sites in the dorsal horn of rat following chronic constriction injury or dorsal rhizotomy.

abstract：:NLP-12a and b have been identified as cholecystokinin/sulfakinin-like neuropeptides in the free-living nematode Caenorhabditis elegans. They are suggested to play an important role in the regulation of digestive enzyme secretion and fat storage. This study reports on the identification and characterization of an NLP-1...
