Abstract
The neuropeptide elevenin and similar neuropeptide precursors are common in some invertebrates but their physiological function in most species has not been explored. The brown planthopper, Nilaparvata lugens (Stål) has an elevenin-like peptide and a G protein-coupled receptor (GPCR) NlA42 that is homologous to the elevenin receptor of the annelid Platynereis dumerilii. RNA interference (RNAi)-mediated knockdown of either Nl-elevenin or the NlA42 gene resulted in cuticle melanization. Ion transport peptide (ITP) also induces melanization, but unlike ITP, knockdown of NlElevenin and NlA42 did not have any effect on wing expansion or activity after eclosion. In wild condition macropterous individuals show a darker body color when compared with brachypterous individuals, but RNAi experiments suggest that insulin-signaling and Nl-elevenin signaling regulate wing morph and body color independently. NlElevenin was predominantly expressed in the brain while NlA42 was highly expressed in the abdominal integument and brain. A signal Calcium assays using aequorin indicated that NlA42 heterologously expressed in HEK293 cells exhibited responses to synthetic Nl-elevenin peptide from concentrations as low as 10-9M. These results suggest that neuropeptide Nl-elevenin is involved in the regulation of melanization through its receptor NlA42. This is the first report of a physiological function for elevenin-like peptides in insects.

Abstract
GPR55 is a G protein-coupled receptor activated by L-α-lysophosphatidylinositol and suggested to have roles in pain signaling, bone morphogenesis, and possibly in vascular endothelial cells. It has affinity for certain cannabinoids (molecules that interact with the cannabinoid CB(1) and CB(2) receptors), but investigation of its functional role in cell-based systems and in tissue has been limited by a lack of selective pharmacological tools. Here, we present our characterization of GPR55 in the yeast Saccharomyces cerevisiae and in human embryonic kidney (HEK293) cells. We describe GSK494581A (1-{2-fluoro-4-[1-(methyloxy)ethyl]phenyl}-4-{[4'-fluoro-4-(methylsulfonyl)-2-biphenylyl]carbonyl}piperazine), a selective small-molecule ligand of GPR55 identified through diversity screening. GSK494581A is one of a series of benzoylpiperazines originally identified and patented as inhibitors of the glycine transporter subtype 1 (GlyT1). The structure-activity relationship between GPR55 and GlyT1 is divergent across this series. The most GPR55-selective example is GSK575594A (3-fluoro-4-(4-{[4'-fluoro-4-(methylsulfonyl)-2-biphenylyl]carbonyl}-1-piperazinyl)aniline), which is approximately 60-fold selective for GPR55 (pEC(50) = 6.8) over GlyT1 (pIC(50) = 5.0). Several exemplars with activity at GPR55 and GlyT1 have been profiled at a broad range of other molecular targets and are inactive at cannabinoid receptors and all other targets tested. The benzoylpiperazine agonists activate human GPR55 but not rodent GPR55, suggesting that the relatively low level of sequence identity between these orthologs (75%) translates to important functional differences in the ligand-binding site.

Abstract
According to The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), ∼70 million European adults have consumed cannabis on at least one occasion. Cannabis consumption leads to a variety of psychoactive effects due to the presence of the constituent Δ(9)-tetrahydrocannabinol (Δ(9)-THC). Δ(9)-THC interacts with the endocannabinoid system (ECS), which consists of the seven transmembrane spanning (7TM)/G protein-coupled receptors (GPCRs) CB(1) and CB(2), their respective ligands (endocannabinoids), and enzymes involved in their biosynthesis and degradation. This system plays a critical role in many physiological processes such as learning and memory, appetite control, pain sensation, motor coordination, lipogenesis, modulation of immune response, and the regulation of bone mass. Therefore, a huge effort has been spent trying to fully elucidate the composition and function of the ECS. The G protein-coupled receptor 55 (GPR55) was recently proposed as a novel component of this system; however, its classification as a cannabinoid receptor has been significantly hampered by its complex pharmacology, signaling, and cellular function. GPR55 is phylogenetically distinct from the traditional cannabinoid receptors, but in some experimental paradigms, it is activated by endocannabinoids, phytocannabinoids, and synthetic cannabinoid ligands. However, the most potent compound appears to be a lysophospholipid known as lysophosphatidylinositol (LPI). Here, we provide a comprehensive evaluation of the current pharmacology and signaling of GPR55 and review the proposed role of this receptor in a number of physiological and pathophysiological processes.

Abstract
Aequorin-based assays for stable fly, Stomoxys calcitrans, (STKR) and human (neurokinin receptor 1 (NK1), neurokinin receptor 2 (NK2)) neurokinin-like receptors were employed to investigate the impact of a C-terminal amino acid exchange in synthetic vertebrate ('FXGLMa') and invertebrate ('FX1GX2Ra') tachykinin-like peptides. C-terminally (Arg to Met) substituted analogs of the insect tachykinin-related peptide, Lom-TK I, displayed increased agonistic potencies in luminescent assays for human NK1 and NK2 receptors, whereas they showed reduced potencies in the STKR-assay. The opposite effects were observed when C-terminally (Met to Arg) substituted analogs of substance P were analysed. These substance P analogs proved to be very potent STKR-agonists, being more potent than Lom-TK I. On the other hand, Lom-TK-LMa, was shown to be a very potent NK1-agonist and was suggested to have more substance-P-mimetic than neurokinin-A-mimetic properties. NK1 and NK2 receptor agonists appeared to be more sensitive to changes at the penultimate amino acid position than STKR-agonists. This is also reflected in the sequence conservation that is observed in the naturally occurring tachykinin subgroups ('FXGLMa' vs. 'FX1GX2Ra'). The differential Arg-Met preference appears to be a major coevolutionary change between insect and human peptide-receptor couples. With regard to the peptide agonists, this change can theoretically be based on a single point mutation.
