Summary: Inflammatory bowel disease (IBD) is a chronic condition characterized by persistent inflammation of the gastrointestinal tract. The cause of IBD is unknown and many patients are unresponsive to medication. Understanding the immunopathogenesis of IBD is crucial for determining its cause and improving treatments.

Summary: This article reviews the potential roles of transient receptor potential (TRP) channels in inflammatory bowel disease (IBD). TRP channels are widely distributed in the gastrointestinal tract and visceral sensory nervous systems and play various roles in physiological and pathological processes. Studies have shown that TRP channels could be novel drug targets for treating IBD.

Summary: This review discusses the mechanisms by which mutations in GPCRs involved in endocrine function in humans lead to misfolding, decreased plasma membrane expression of the receptor protein, and loss-of-function diseases. Special attention is given to misfolded GPCRs that regulate reproductive function, and promising therapeutic interventions targeting trafficking of these defective proteins to rescue their normal function are also described.

Summary: This review explores the signaling pathways, dynamic structures, and physiological relevance of the three most important GPCR signaling effectors in the cardiovascular system: heterotrimeric G proteins, GPCR kinases (GRKs), and 8-arrestins. It summarizes their prominent roles in GPCR pharmacology before transitioning into less well-explored areas. The application of new technologies has contributed to an increasing understanding of GPCR structure and downstream effectors.

Summary: This article discusses a new approach, using oxidation-resistant hexadeuterated arachidonic acid (D-ARA), to attenuate pathological inflammatory reactions by buffering the eicosanoid pathways. Enzymatic processing of released arachidonic acid by phospholipase A2 yields bioactive eicosanoids, some of which have pro-inflammatory, pro-angiogenesis, and pro-thrombosis effects. D-ARA, resistant to both enzymatic and non-enzymatic oxidation pathways, may play a role in mitigating inflammation-related disorders.

Summary: In this study, a highly sensitive and specific method for screening and annotating epoxy/dihydroxy-oxylipins in biological samples was established using chemical labeling-assisted liquid chromatography coupled with high-resolution mass spectrometry. The analysis revealed the presence of potential epoxy/dihydroxy-oxylipins, including previously unreported compounds, in human serum and high-fat diet mouse heart samples. Moreover, the method showed a significant decrease in the levels of certain epoxy/dihydroxy-oxylipins in the heart of mice with high-fat diet, particularly those derived from linoleic acid or alpha-linolenic acid.

Summary: This study provides evidence that heteromerization of G protein-coupled receptors (GPCRs), specifically dopamine D1 and D3 receptors, can influence the pharmacological properties of selective ligands. In vivo experiments support the involvement of D1R-D3R heteromers in the development of L-DOPA-induced dyskinesia in Parkinson's disease, suggesting the potential of targeting GPCR heteromers for drug development.

Summary: Heart failure remains a significant cause of morbidity and mortality worldwide. Current treatment options have limitations, leading to many patients progressing to advanced stages. Exploration of novel therapeutics targeting G protein-coupled receptors (GPCRs) has shown promise, but efficacy and unwanted effects remain as challenges.

Summary: The study used transcriptome and secretome profiling to analyze the signaling and function of ectopic P2Y(11) receptors, which were validated in human monocyte-derived M2 macrophages. The results showed that targeting P2Y(11) receptors can activate IL-1 receptor signaling to promote sTNFR2 release and suppress TLR4 signaling, facilitating resolution of inflammation.

Summary: Dopamine transmission in the striatum is regulated by various G protein-coupled receptors (GPCRs) that bind neuromodulators, including dopamine itself. These GPCRs can modulate dopamine release by acting on different components of the dopaminergic circuitry and can have distinct effects on behavior and psychoactive drug actions. This review discusses the mechanisms by which GPCRs regulate dopaminergic transmission and their relevance to the effects of psychoactive drugs on physiology and behavior.

Summary: In this study, an eight-week feeding trial was conducted to evaluate the regulatory effects of dietary Arachidonic acid (ARA) and its metabolites on inflammation, oxidative stress, and apoptosis in Acanthopagrus schlegelii. Results showed that high levels of dietary ARA induced inflammation by activating the gene expression levels of nuclear factor kappa B (nf-kappa b) and oxidative stress by reducing antioxidant parameters. Additionally, excess ARA levels promoted cell apoptosis by up-regulating pro-apoptotic gene expression levels.

Summary: The study examined the role of LTB4-BLT1 signaling in postoperative incisional pain and found that LTB4 exacerbates pain responses through promoting local infiltration of inflammatory monocytes and cytokine production. Therefore, LTB4-BLT1 signaling could be a potential therapeutic target for acute and persistent pain induced by tissue injury.

Summary: In vertebrates, nutritional tastants are recognized by taste receptor type 1 (T1R) family. Zebrafish and medaka fish have oral receptors highly sensitive to amino acids, especially l-proline. Functional assays confirmed the presence of specific T1Rs in these fish, reflecting the physiological importance of l-proline in teleosts.

Summary: Leukotriene B-4 (LTB4) is a chemotactic factor for inflammatory cells derived from arachidonate, and an important drug target. The high-affinity LTB4 receptor, BLT1, is involved in the pathogenesis of various inflammatory and immune diseases. The low-affinity receptor, BLT2, is a receptor for 12-hydroxyheptadecatrienoic acid and is involved in maintaining barrier function and promoting wound healing. BLT1 antagonists and BLT2 agonists are potential candidates for treating inflammatory diseases.

Summary: This study created a docked model of the transmembrane domain (TMD) of the T1R3 subunit of the human sweet taste receptor with neohesperidin dihydrochalcone (NHDC) and identified important residues for NHDC recognition. The docking mode of NHDC with T1R3 TMD was distinct from that of lactisole, a sweet taste inhibitor.
