Abstract
The RFamide peptide family is a group of proteins that share a common C-terminal arginine-phenylalanine-amide motif. To date, the family comprises five groups in mammals: neuropeptide FF, LPXRFamides/RFamide-related peptides, prolactin releasing peptide, QRFP, and kisspeptins. Different RFamide peptides have their own cognate receptors and are produced by different cell populations, although they all can also bind to neuropeptide FF receptors with different affinities. RFamide peptides function in the brain as neuropeptides regulating key aspects of homeostasis such as energy balance, reproduction, and cardiovascular function. Furthermore, they are involved in the organization of the stress response including modulation of pain. Considering the interaction between stress and various parameters of homeostasis, the role of RFamide peptides may be critical in the development of stress-related neuropathologies. This review will therefore focus on the role of RFamide peptides as possible key hubs in stress and stress-related psychopathologies. The neurotransmitter coexpression profile of RFamide-producing cells is also discussed, highlighting its potential functional significance. The development of novel pharmaceutical agents for the treatment of stress-related disorders is an ongoing need. Thus, the importance of RFamide research is underlined by the emergence of peptidergic and G-protein coupled receptor-based therapeutic targets in the pharmaceutical industry.

Abstract
Neuropeptide FF (NPFF) and Neuropeptide VF (NPVF) are part of the extended RFamide peptide family characterized by their common arginine (R) and amidated phenylalanine (F)-motif at the carboxyl terminus. Both peptides signal through their respective high affinity G-protein coupled receptors, NPFFR2 and NPFFR1, but also show binding affinity for the other receptor due to their sequence similarity. NPFF and NPVF are highly conserved throughout evolution and can be found across the whole animal kingdom. Both have been implicated in a variety of biological mechanisms, including nociception, locomotion, reproduction, and response to pain and stress. However, more recently a new major functional role in the control of energy homeostasis has been discovered. In this article we will summarise the current knowledge on the distribution of NPFF, NPVF, and their receptors in central and peripheral tissues, as well as how this relates to the regulation of food intake and energy balance, which will help to better understand their role in these processes and thus might help finding treatments for impaired energy homeostasis disorders, such as obesity or anorexia.

Abstract
RF-amide neuropeptides, with their typical Arg-Phe-NH2 signature at their carboxyl C-termini, belong to a lineage of peptides that spans almost the entire life tree. Throughout evolution, RF-amide peptides and their receptors preserved fundamental roles in reproduction and feeding, both in Vertebrates and Invertebrates. The scope of this review is to summarize the current knowledge on the RF-amide systems in Mammals from historical aspects to therapeutic opportunities. Taking advantage of the most recent findings in the field, special focus will be given on molecular and pharmacological properties of RF-amide peptides and their receptors as well as on their implication in the control of different physiological functions including feeding, reproduction and pain. Recent progress on the development of drugs that target RF-amide receptors will also be addressed.

Wu CH, Tao PL, Huang EYK. Distribution of neuropeptide FF (NPFF) receptors in correlation with morphine-induced reward in the rat brain. Peptides 2010; 31:1374-82. [PMID: 20381562 DOI: 10.1016/j.peptides.2010.03.036] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2010] [Revised: 03/31/2010] [Accepted: 03/31/2010] [Indexed: 11/29/2022]
Abstract
Neuropeptide FF (NPFF) exhibited anti-/pro-opioid effects when centrally injected. It was proved to bind to its own receptors, namely NPFF(1) and NPFF(2) receptors, but did not bind to opioid receptors. In our previous study, we found that i.c.v. injected NPFF suppressed morphine-induced conditioned place preference (CPP) in rats, which indicated that NPFF may play a role in the modulation of morphine-induced reward. In the present study, we further investigated the action site of NPFF to attenuate morphine-induced reward. Bilateral intra-VTA (ventral tegmental area) and intra-NAc (nucleus accumbens) injections of NPFF both blocked the CPP caused by morphine in rats. This suggests that NPFF may act at both VTA and NAc to inhibit the sensitization of the mesocorticolimbic dopaminergic pathway. Neurochemical analyses support that NPFF could be acting through the inhibition of the mesocorticolimbic dopaminergic activity increased by morphine. We also determined the distribution of NPFF receptors in rat brains. Our results showed that both NPFF receptors were abundantly expressed in VTA but with less content in NAc. In fluorescent immunohistochemical staining, our results revealed that NPFF(1) and NPFF(2) receptors could be expressed at the TH (tyrosine hydroxylase)- or GAD67 (glutamic acid decarboxylase-67)-positive neurons in VTA, whereas some of them were present in the negative neurons. This implied a possible function of NPFF to modulate dopaminergic neurons directly and a possible indirect action of NPFF on GABAergic neurons to modulate dopamine release. Taken together, our study should be helpful for clarifying the possible mechanisms of NPFF system to modulate morphine-induced reward.

Abstract
This study presents the binding and functional properties of the mouse NPFF(2) (mNPFF(2)) receptor, in comparison with its human counterpart (hNPFF(2)). Binding experiments were performed by using the NPFF(2) selective radioligand [(3)H]-EYF in membranes from CHO cells transfected with mouse and human NPFF(2) receptors and compared to membranes from mouse olfactory bulb, the brain region expressing the highest density of NPFF(2) receptors in mouse. mNPFF(2) receptors exhibited a high affinity (Kd=0.2-0.4 nM) for [(3)H]-EYF, comparable to that of hNPFF(2) receptors. Also, the binding selectivity profile of mNPFF(2) receptors was comparable to that of hNPFF(2) receptors, except for three ligands (NPSF, NPVF, RF9) that were about tenfold more potent and active on mouse receptors than on human receptors. In particular, compared to hNPFF(2) receptors, mNPFF(2) receptors were less discriminative towards the proNPFF(B)-derived peptide. This suggests some species-related differences in the binding properties of NPFF(2) receptors that could have repercussion when evaluating the pharmacological properties of drugs in vivo.
