Summary: The study identified MCOPB as a NOP ligand with tissue-specific senolytic effects, reducing the senescent cell burden in peripheral tissues but not affecting the central nervous system. Additionally, exposure to MCOPB led to changes in locomotion and lipid storage. Mechanistically, MCOPB treatment activated transcriptional networks involved in immune responses to external stressors, implicating Toll-like receptors (TLRs).

Summary: This study evaluated the effects of two NOPR agonists on sleep/wake in rats, mice, and Cynomolgus macaques. The results showed that these agonists increased non-Rapid Eye Movement sleep and electroencephalogram slow wave activity, while suppressing Rapid Eye Movement sleep in all three species. These findings suggest that the N/OFQ-NOPR system may have a previously unrecognized role in sleep/wake control and could be a potential therapeutic target for insomnia.

Summary: Nociceptin/orphanin FQ (N/OFQ) is a neuropeptide that binds the NOP receptor and exerts anti-opioids effects; the NOP receptor is widely expressed in the brain, while N/OFQ is mainly localized in stress-related brain nuclei; preclinical evidence suggests that both NOP agonists and antagonists may be effective therapeutic approaches for substance use disorders.

Summary: Genetic deletion or pharmacological blockade of NOP receptors have shown to reduce nicotine intake and motivation to self-administer in rats. The NOP receptor antagonist LY2817412 decreased nicotine intake in wild-type rats, confirming its effect is mediated by inhibition of NOP transmission. Injection of LY2817412 into the VTA decreased nicotine self-administration, suggesting that NOP receptor antagonism may be a potential treatment for smoking cessation.

Summary: In our society today, pain has become a significant source of strain on individuals. Developing new pain treatments with fewer adverse effects is crucial. The NOP receptor has emerged as a promising focal point for novel pain therapies, offering an alternative to opioid morphine with potential life-threatening effects and addiction. This article reviews the molecular and cellular structure controlling the cellular trafficking of the NOP receptor and presents studies supporting its role in pain management.

Summary: The genetically selected Marchigian Sardinian alcohol-preferring (msP) rats exhibit innate up-regulation of the CRF system for negative mood and stress responses, as well as inherent up-regulation of the N/OFQ system for anti-stress responses. Alcohol consumption dampens N/OFQ and results in a complex reorganization of neuropeptidergic systems in the extended amygdala of msP rats.

Summary: In this study, the role of N/OFQ-NOP system was explored in freshly isolated volunteer human B- and T-cells incubated with LPS and PepG as a model of in vitro sepsis. The findings suggest that N/OFQ-NOP receptors play a regulatory role in B and T cell function, inhibiting cell migration and reducing GM-CSF release to variable degrees.

Summary: This article reviews the role of the N/OFQ-NOP receptor system in the neurological and behavioral sequelae of PTSD and TBI. The current findings suggest that NOP modulators may have potential as therapeutics for these disorders and their co-morbidities. The authors advocate for the development of standards for common data elements reporting to improve reproducibility and data sharing.

Summary: This study investigated the relationship between nociceptin opioid peptide receptor (NOP) and relapse to alcohol in treatment-seeking individuals with alcohol use disorder (AUD). The results showed that individuals with AUD who drank heavily before the study had lower levels of NOP, which were also negatively correlated with drinking frequency and quantity. Individuals with AUD who relapsed had lower levels of NOP compared to those who abstained for 12 weeks. The study highlights the potential of investigating NOP-targeted medications for preventing relapse in individuals with AUD.

Summary: We investigated the effects of opioids on the coexpressed mu-opioid (MOP) and nociceptin/orphanin FQ (NOP) receptors in human embryonic kidney (HEK) 293 cells. Our findings suggest that morphine, but not buprenorphine, facilitates the formation of MOP-NOP heterodimers and enhances their localization on lipid rafts. Moreover, morphine stimulates the phosphorylation of Erk1/2 in cells expressing MOP and MOP+NOP receptors, while buprenorphine appears to activate Erk1/2 solely through NOP receptors.

Summary: This study found that the agonist of the NOP receptor can induce chronic depressive effects, which may or may not be influenced by social defeat stress. We suggest that NOP receptor signaling may activate pathways involved in cellular oxidative stress, contributing to the pathology of depression.

Summary: Traumatic brain injury (TBI) affects millions of people each year and is a leading cause of death and disability. This study suggests that the N/OFQ-NOP receptor pathway plays a significant role in regulating cerebral blood flow and injury markers in TBI, indicating that the NOP receptor could be a potential therapeutic target for TBI.

Summary: Antibiotic resistance is a major threat to public health, with Gram-negative bacteria presenting unique challenges due to their low permeability and efflux pumps. Limited understanding of the chemical rules for overcoming these barriers hinders antibacterial drug discovery. Efforts to address this issue, such as screening compound libraries and using cheminformatic analysis, have led to the design of sulfamidoadenosines with diverse substituents, showing potential utility in accumulation in Escherichia coli.

Summary: This study successfully developed a short peptide mimetic as a MERS-CoV fusion inhibitor by reproducing the key recognition features of the HR2 helix. The resulting 23-mer lipopeptide showed comparable inhibitory effect to the 36-mer HR2 peptide HR2P-M2. This has important implications for developing short peptide-based antiviral agents to treat MERS-CoV infection.

Summary: Beta(2)-adrenergic receptor agonists can stimulate glucose uptake by skeletal muscle cells and are therefore potential treatments for type 2 diabetes. The chirality of compounds has a significant impact on the activity of these agonists. This study found that certain synthesized compounds showed higher glucose uptake activity. These findings provide important information for the design of novel beta(2)AR agonists for T2D treatment.
