Abstract:
Despite similar distribution patterns and intracellular events observed in the nociceptin/ orphanin FQ peptide (NOP) receptor and other opioid receptors, NOP receptor activation displays unique pharmacological profiles. Several researchers have identified a variety of peptide and nonpeptide ligands to determine the functional roles of NOP receptor activation and observed that NOP receptor- related ligands exhibit pain modality-dependent pain processing. Importantly, NOP receptor activation results in anti-nociception and anti-hypersensitivity at the spinal and supraspinal levels regardless of

We attempted to examine the alterations elicited by opioids via coexpressed μ-opioid (MOP) and nociceptin/orphanin FQ (NOP) receptors for receptor localization and Erk1/2 (p44/42 MAPK) in human embryonic kidney (HEK) 293 cells. Through two-photon microscopy, the proximity of MOP and NOP receptors was verified by fluorescence resonance energy transfer (FRET), and morphine but not buprenorphine facilitated the process of MOP-NOP heterodimerization. Single-particle tracking (SPT) further revealed that morphine or buprenorphine hindered the movement of the MOP-NOP heterodimers. After exposure to m

Abstract:
Sepsis is a dysregulated host response to infection that can cause widespread effects on other organs including cardiovascular depression, hypotension and organ failure. The receptor for Nociceptin/Orphanin FQ (N/OFQ), NOP is expressed on immune cells and these cells can release the peptide. Exogenous N/OFQ can dilate blood vessels and this peptide is increased in animal and human sepsis. We hypothesise that NOP receptors are present on vascular endothelial cells and therefore provide the target for released N/OFQ to cause vasodilation and hence hypotension.

Abstract:
Opioids targeting mu;μ (MOP) receptors produce analgesia in the peri-operative period and palliative care. They also produce side effects including respiratory depression, tolerance/dependence and addiction. The N/OFQ opioid receptor (NOP) also produces analgesia but is devoid of the major MOP side effects. Evidence exists for MOP-NOP interaction and mixed MOP-NOP ligands produce analgesia with reduced side effects. We have generated a HEKMOP/NOP human expression system and used bivalent MOP-NOP and fluorescent ligands to (i) probe for receptor interaction and (ii) consequences of that interac

Agonists of the nociceptin/orphanin FQ opioid peptide (NOP) receptor, a member of the opioid receptor family, are under active investigation as novel analgesics, but their modes of signaling are less well characterized than those of other members of the opioid receptor family. Therefore, we investigated whether different NOP receptor ligands showed differential signaling or functional selectivity at the NOP receptor.

The opioid receptor-like 1 (NOP or ORL1) receptor is a G-protein-coupled receptor the endogenous ligand of which is the heptadecapeptide, nociceptin (Noc). NOP receptors are known to modulate pain processing at spinal, supraspinal, and peripheral levels. Previous work has demonstrated that NOP receptors inhibit N-type Ca2+ channel currents in rat sympathetic stellate ganglion (SG) neurons via pertussis toxin (PTX)-sensitive Gαi/o subunits. However, the identification of the specific Gα subunit that mediates the Ca2+ current modulation is unknown. The purpose of the present study was to examine

ADP is an important in vivo mediator of platelet aggregation. The identification and estimation of a finite number of receptor sites has been made difficult by the reversible nature of the action of ADP on platelets and because ADP can be degraded by enzymes on the platelet surface.

We investigated the validity of using 5'-p-fluorosulfonylbenzoyl adenosine (FSBA), an affinity analogue of ADP that inhibits ADP-induced aggregation, for studying the ADP receptor on intact washed platelets.

Relative abundance also varies greatly. The goal of this study is to relate the spectral properties of receptor systems to those of wing patterns. Spectral sensitivity functions of each spectral type of receptor are measured optophysiologically. Reflectance spectra of wing patches a

Abstract:
Azido-BSP (4-[2-(4-azido-benzenesulphonylamino)-ethyl]phen-oxyacetic acid) is a photolabile derivative of the competitive thromboxane A2 /prostaglandin H2 (TXA2/PGH2) receptor antagonist sulotroban (=BM 13.177). If protected from short wave light, azido-BSP reversibly inhibited the platelet shape change induced by the PGH2 analogue U 46619 but notthe shape change induced by ADP or PAF. Schild analysis revealed an apparent KD=0.2 μM with washed platelets. The irreversible inhibition requiredirradiation of the platelet suspensionwith UVlight (254 nm) for 5 minutes in the presenceof azido-BSP. Af

Abstract:
The uptake, internalization and intracellular degradation of 125I-labeled rt-PA (125I-rt-PA) by isolated rat hepatocytes was investigated. Incubation at 37°C resulted in internalization of 125I-rt-PA, followed by the appearance of labeled trichloroacetic acid-soluble (TCA) material in the inclubation media due to degradation of rt-PA. Degradation of rt-PA was inhibited by the presence of NH4Cl (10mM) or chloroquine (ImM) (lysosoma tropic agents) in the incubation media. This suggests that rt-PA degradation occurs intracellularly, perhaps within the lysosomes. 125I-rt-PA was taken up by rat hep

Prostaglandin endoperoxides (PGEND) and thromboxane A2 (TxA2)contribute to the activation of platelets, involving inositol-containing phospholipids as a signal transducing system. A primary step in this signal transduction consists of the activation of phospholipase C, which then yields diacylglycerol and inositol phosphates;diacylglycerol is subsequently phosphorylated to phosphatidic acid (PA). In platelets prelabelled with [32P] orthophosphate,receptor activation is quantitatively reflected by an increased formation of [32P]-PA.Using this assay, the relativeimportance of endogenously genera

Insulin receptors have been found not only on its “target Cells” but also on several other cell-types, including human platelets. From studies on adipocytes and liver cells it seems that they are coupled both to the adenylate cyclase-cyclic AMP and the polyphosphoinositide messenger systems. Circulating blood cells might faithfully reflect the insulin receptor state of target organ tissues. Impaired platelet function has an important role in the pathogenesis of vascular and thrombotic complications in diabetes mellitus, and insulin seems to act directly on platelets.

The general objective of this study was to develop rationally designed mimetic antagonists (and agonists) of the PK/PBAN Np class with enhanced bio-stability and bioavailability as prototypes for effective and environmentally friendly pest insect management agents. The PK/PBAN family is a multifunctional group of Nps that mediates key functions in insects (sex pheromone biosynthesis, cuticular melanization, myotropic activity, diapause and pupal development) and is, therefore, of high scientific and applied interest.

Abstract:
Voltage-gated sodium channels (Navs) play a pivotal role in excitability and are a prime target of insecticides like pyrethroids. Yet, these insecticides are non-specific due to conservation of Navs in animals, raising risks to the environment and humans. Moreover, insecticide overuse leads to resistance buildup among insect pests, which increases misuse and risks. This sad reality demands novel, more selective, insect killers whose alternative use would avoid or reduce this pressure. As highly selective insect toxins exist in venomous animals, why not exploit this gift of nature and harness t

Many factors affect growth rate in fish: environmental, nutritional, genetics and endogenous (physiological) factors. Endogenous control of growth is very complex and many hormone systems are involved. Nevertheless, it is well accepted that growth hormone (GH) plays a major role in stimulating somatic growth. Although it is now clear that most, if not all, components of the GH-IGF axis exist in fish, we are still far from understanding how fish grow.

Abstract:
Pattern-recognition receptors (PRRs) located on the plant cell surface initiate immune responses by perceiving conserved pathogen molecules known as pathogen-associated molecular patterns (PAMPs). PRRs typically function in multiprotein complexes that include transmembrane and cytoplasmickinases and contribute to the initiation and signaling of pattern-triggered immunity (PTI). An important challenge is to identify molecular components of PRR complexes and downstream signaling pathways, and to understand the molecular mechanisms that mediate their function.
