Disruption of this signalling may have deleterious phenotypic consequences, including altered locomotion, feeding behaviour, and reproduction. Neuropeptide G protein-coupled receptors (GPCRs) that transduce many of these signals therefore represent cogent drug targets. Recently published genomic sequencing data for a number of parasitic helminths of medical and veterinary importance has revealed the apparent conservation of a number of neuropeptides, and neuropeptide receptors between parasitic and free-living species, raising the intriguing possibility of developing broad-spectrum anthelmintic therapeutics. Here, we identify and clone a neuropeptide receptor, NPR-4, from the human filarial nematode Brugia malayi and demonstrate its activation in vitro, by FMRFamide-like peptides of the FLP-18 family, and intracellular signalling via G i mediated pathways. These data represent the first example of deorphanisation of a neuropeptide GPCR in any parasitic helminth species.en© 2014 Elsevier B.V. All rights reserved.
