Bursicon receptor gene HLGR2 as a potential RNA interference target for control of the fall webworm Hyphantria A functional study of the leucine-rich repeat-containing (LGR2) gene in Hyphantria cunea (HLGR2) was The spatiotemporal expression profiles of HLGR2 showed that HLGR2 was highly expressed at the egg stage Unlike LGR2 in other insect species, HLGR2 was found to play a crucial role in the control of H. cunea Conclusion: HLGR2 is essential for the growth and development and wing expansion and maturation in H.

by spiral ganglion neurons (SGNs) and heard by the auditory cortex. disorders, and the treatment for hearing loss. Recently, several GPCRs have been found to play important roles in the cochlea. And A1, A2A, and CB2 activation by agonists has protective functions on noise- or drug-induced hearing such as stem cell fate, PCP, hearing loss, and hearing protection."

October 2022 Recurrent hypoglycemia increases hepatic gluconeogenesis without affecting glycogen metabolism or systemic lipolysis in rat "Introduction: Recurrent hypoglycemia (RH) impairs secretion of counterregulatory hormones. Whether and how RH affects responses within metabolically important peripheral organs to counterregulatory hormones are poorly understood.

"The canonical model for G protein-coupled receptors (GPCRs) activation assumes that stimulation of heterotrimeric However, over the last decade, this model has been extended by discovering that some internalized GPCRs This is the case for the parathyroid hormone (PTH) type 1 receptor (PTHR), which engages on sustained Accumulative evidence shows that the location of signaling has an impact on the physiological effects

October 2022 "Endogenous parathyroid hormone (PTH) and PTH-related peptide (PTHrP) bind to the parathyroid hormone receptor 1 (PTH1R) and activate the stimulatory G-protein (Gs) signaling pathway. Intriguingly, the two ligands have distinct signaling and physiological properties: PTH evokes prolonged Here, we report cryoelectron microscopic structures of six forms of the human PTH1R-Gs complex in the

October 2022 "Herpesviruses are ancient large DNA viruses that have exploited gene capture as part of their strategy to escape immune surveillance, promote virus spreading, or reprogram host cells to benefit This review focuses on the vGPCRs encoded by the human β- and γ-herpesviruses. UL78; human herpesvirus 6 and 7 with two receptors: U12 and U51; Epstein-Barr virus with one: BILF1; and Kaposi's sarcoma-associated herpesvirus with one: open reading frame 74, ORF74.

October 2022 "Psychedelics, also known as classical hallucinogens, affect processes related to perception , cognition and sensory processing mostly via the serotonin 5-HT2A receptor (5-HT2AR). Current studies focused on the potentially clinical effects of psychedelics on human subjects tend to Here we tested the effects of DOI on head-twitch behavior (HTR) - a mouse behavioral proxy of human psychedelic Volinanserin (or M100907) - a 5-HT2AR antagonist - fully prevented DOI-induced HTR in male and female

Mutations in VLGR1 have been associated with the human Usher syndrome (USH), the most common form of of VLGR1 with components in MAMs and point to an essential role of VLGR1 in the regulation of Ca2+ homeostasis

Neuropeptides and their receptors have been documented in many hemipteran insects, but the differences among them have been poorly characterized. Here, 33 neuropeptide precursors and 48 putative neuropeptide G protein-coupled receptor (GPCR) genes By comparison, we found that the Releasing Hormone-Related Peptides (GnRHs) system of Sternorrhyncha was differentiated from those of the other 2 suborders in Hemiptera.

regulating schizophrenia-relevant brain circuits "Although the cannabinoid type-2 receptor (CB2) is highly that CB2 receptors are expressed in specific dopaminergic and glutamatergic brain circuits that are hyperactive The ability of CB2 receptors to inhibit dopaminergic and hippocampal circuits, combined with the anti-inflammatory and genetic tools, including the first small molecule positive allosteric modulator of CB2 receptors, has

August 2022 TAS2R supports odontoblastic differentiation of human dental pulp stem cells in the inflammatory microenvironment "Background: Inflammatory microenvironment promotes odontoblastic differentiation in human dental pulp stem cells (hDPSCs), but the regulatory mechanisms remain unclear. In this study, we aimed to explore the role of TAS2R in odontoblastic differentiation of hDPSCs in the pulp tissues from the patients. hDPSCs isolated from the healthy pulp tissues were stimulated by LPS

August 2022 "Histamine exerts its physiological functions through its four receptor subtypes. In this work, we report the subcellular localization of histamine receptor 2 (H2R), a G protein-coupled Using fluorescently tagged histamine, we explored H2R-histamine binding interaction, which exhibits a Altogether, our results highlight the previously unrecognized nuclear localization pattern of H2R. H2R blockers are commonly used medications that recently have shown significant side effects.

August 2022 "Host response to infection involves the activation of the complement system leading to the Here, we discuss recent crystal structures of inactive C5aR1 in terms of an inverted orientation of helix H8, unobserved in other GPCR structures. An analysis of mutual interactions of subunits in the C5aR1-G protein complex has provided new insights transmembrane domain induced by interactions with the Gα subunit and explained the impact of inverted H8

September 2022 "The activation of phospholipase C (PLC) is thought to have a key role in the cardiomyocyte response to several different hypertrophic agents such as norepinephrine, angiotensin II and endothelin that PLC activities may be part of a coordinated signaling process for the perpetuation of cardiac hypertrophy provided, it is plausible that specific PLC isozymes could be targeted for the mitigation of cardiac hypertrophy

September 2022 "Experimental studies proposed a direct effect of follicle-stimulating hormone (FSH) on the skeletal metabolism, but results of human studies mainly conducted in females are controversial. The present study aims to investigate the possible role of FSH excess in male bone health, by comparing for the first time primary and central hypogonadism."

(HH) bundles. However, the nature of interactions between VFT units and HH bundles, and the impacts of heterozygous or homozygous inactivating mutations, which have implications for disorders of calcium metabolism are Mutant heterodimers containing one wild-type (WT) and one mutant VFT domain, however, corresponding to heterozygous familial hypocalciuric hypercalcemia type-1 (FHH-1), supported maximal signaling with reduced

September 2022 A2B Adenosine Receptor Enhances Chemoresistance of Glioblastoma Stem-Like Cells under Hypoxia However, adenosine/MRPs-dependent chemoresistance under hypoxia has not been studied until now. Here, we show for the first time that MRP3 expression is induced under hypoxia through the A2B adenosine Hypoxia enhances MRP-dependent extrusion capacity and the chemoresistance of GSCs. Meanwhile, MRP3 knockdown decreases GSC viability under hypoxia.

Recent studies in experimental animals have shown that certain subsets of T cells express functional In contrast, less is known about the expression and function of the GLP-1R in human T cells. Here, we provide evidence that activated human T cells express GLP-1R. Given the high induction of GLP-1R in human iTreg cells, we hypothesize that GLP-1R+ iTreg cells play a key role in the anti-inflammatory effects ascribed to GLP-1R agonists in humans."
