Ligand selectivity in tachykinin and natalisin neuropeptidergic systems of the honey bee parasitic mite Varroa destructor. Sci Rep 2016; 6:19547.

Abstract
The varroa mite, Varroa destructor, is a devastating ectoparasite of the honey bees Apis mellifera and A. cerana. Control of these mites in beehives is a challenge in part due to the lack of toxic agents that are specific to mites and not to the host honey bee. In searching for a specific toxic target of varroa mites, we investigated two closely related neuropeptidergic systems, tachykinin-related peptide (TRP) and natalisin (NTL), and their respective receptors. Honey bees lack both NTL and the NTL receptor in their genome sequences, providing the rationale for investigating these receptors to understand their specificities to various ligands. We characterized the receptors for NTL and TRP of V. destructor (VdNTL-R and VdTRP-R, respectively) and for TRP of A. mellifera (AmTRP-R) in a heterologous reporter assay system to determine the activities of various ligands including TRP/NTL peptides and peptidomimetics. Although we found that AmTRP-R is highly promiscuous, activated by various ligands including two VdNTL peptides when a total of 36 ligands were tested, we serendipitously found that peptides carrying the C-terminal motif -FWxxRamide are highly specific to VdTRP-R. This motif can serve as a seed sequence for designing a VdTRP-R-specific agonist.

Paluzzi JP, O'Donnell MJ. Identification, spatial expression analysis and functional characterization of a pyrokinin-1 receptor in the Chagas' disease vector, Rhodnius prolixus. Mol Cell Endocrinol 2012; 363:36-45.

Abstract
The capability or capa gene, encodes a pyrokinin-related peptide (known as pyrokinin-1, PK1) that contains the consensus carboxy-terminal sequence of WFGPRL-NH(2). Although the CAPA precursor polypeptide in Rhodnius prolixus yields the anti-diuretic hormone, RhoprCAPA-α2, no function has yet been elucidated for the pyrokinin-1 peptide, RhoprCAPA-αPK1. In order to elucidate the possible physiological roles of the PK1-related peptides in R. prolixus, we have isolated and functionally characterized the PK1 receptor, RhoprPK1-R. Additionally, we have determined a set of three optimal reference genes to utilize for normalization of data obtained when carrying out spatial expression analyses via quantitative reverse transcriptase PCR (RT-qPCR) in various tissues of fifth instar R. prolixus. The RhoprPK1-R expression profile differs strikingly from the receptor for the anti-diuretic hormone RhoprCAPA-α2, which is localized mainly to gut epithelial tissues. Instead, RhoprPK1-R expression in fifth instar stage insects was identified in tissues that are not involved in osmotic and ionic balance, including the prothoracic glands, male reproductive tissues and a pooled sample composed of fat body, dorsal vessel, abdominal nerves and female reproductive tissues. Thus, this research establishes novel possibilities for the physiological roles of the pyrokinin-related peptides in this medically relevant disease vector.

Abstract
Neuropeptides represent the largest single class of signal compounds and are involved in regulation of development, growth, reproduction, metabolism and behavior of insects. Over the last few years there has been a tremendous increase in our knowledge of neuropeptide signaling due to genome sequencing, peptidomics, gene micro arrays, receptor characterization and targeted gene interference combined with physiological and behavior analysis. In this chapter we review the current knowledge of structure and distribution of insect neuropeptides and their receptors, as well as their diverse functions. We also discuss peptide biosynthesis, processing and expression, as well as classification of insect neuropeptides. Special attention is paid to the role insect neuropeptides play as potential targets for pest management and as a basis for development of insect control agents employing the rational/structural design approaches.
