Therefore, insights into molecular mechanisms that regulate insulin homeostasis might provide entry sites to replenish insulin content and restore β cell function. Here, we identify the insulin inhibitory receptor (inceptor; encoded by the gene IIR/ELAPOR1) as an insulin-binding receptor that regulates insulin stores by lysosomal degradation. Using human induced pluripotent stem cell (SC)-derived islets, we show that IIR knockout (KO) results in enhanced SC β cell differentiation and survival. Strikingly, extended in vitro culture of IIR KO SC β cells leads to greatly increased insulin content and glucose-stimulated insulin secretion (GSIS). We find that inceptor localizes to clathrin-coated vesicles close to the plasma membrane and in the trans-Golgi network as well as in secretory granules, where it acts as a sorting receptor to direct proinsulin and insulin towards lysosomal degradation. Targeting inceptor using a monoclonal antibody increases proinsulin and insulin content and improves SC β cell GSIS. Altogether, our findings reveal the basic mechanisms of β cell insulin turnover and identify inceptor as an insulin degradation receptor. The insulin inhibitory receptor (inceptor) is found to bind to insulin and to regulate insulin stores by directing proinsulin and insulin towards lysosomal degradation.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"6 12","pages":"2374-2390"},"PeriodicalIF":18.9,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42255-024-01164-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142697062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acyl coenzyme A binding protein (ACBP, encoded by the gene diazepam binding inhibitor, Dbi) stimulates food intake and lipo-anabolic reactions. Here we found that plasma ACBP/DBI concentrations were elevated in patients and mice with Cushing’s syndrome. We used several methods for ACBP/DBI inhibition in mice, namely, (1) induction of ACBP/DBI autoantibodies, (2) injection of a neutralizing monoclonal antibody, (3) body-wide or hepatocyte-specific knockout of the Dbi gene, (4) mutation of the ACBP/DBI receptor Gabrg2 and (5) injections of triiodothyronine or (6) the thyroid hormone receptor-β agonist resmetirom to block Dbi transcription. These six approaches abolished manifestations of Cushing’s syndrome such as increased food intake, weight gain, excessive adiposity, liver damage, hypertriglyceridaemia and type 2 diabetes. In conclusion, it appears that ACBP/DBI constitutes an actionable target that is causally involved in the development of Cushing’s syndrome. The authors highlight the role of acyl coenzyme A binding protein (encoded by DBI) in Cushing’s syndrome by using six different inhibition methods and mapping the physiological effects.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"6 12","pages":"2281-2299"},"PeriodicalIF":18.9,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42255-024-01170-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is associated with many malignancies and significantly contributes to cancer-related morbidity and mortality. With emerging recognition of cancer as a systemic disease, there is increasing awareness that understanding and treatment of cancer cachexia may represent a crucial cornerstone for improved management of cancer. Here, we describe the metabolic changes contributing to body wasting in cachexia and explain how the entangled action of both tumour-derived and host-amplified processes induces these metabolic changes. We discuss energy homeostasis and possible ways that the presence of a tumour interferes with or hijacks physiological energy conservation pathways. In that context, we highlight the role played by metabolic cross-talk mechanisms in cachexia pathogenesis. Lastly, we elaborate on the challenges and opportunities in the treatment of this devastating paraneoplastic phenomenon that arise from the complex and multifaceted metabolic cross-talk mechanisms and provide a status on current and emerging therapeutic approaches. In this Review, the authors highlight cancer cachexia as a complex and multifactorial disorder, and discuss the underlying host-driven and tumour-driven metabolic changes, therapeutic opportunities and the pertinent challenges in the treatment of cancer cachexia.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"6 12","pages":"2222-2245"},"PeriodicalIF":18.9,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme of salvage nicotinamide adenine dinucleotide (NAD+) synthesis, is an interferon-inducible protein that inhibits the replication of several RNA and DNA viruses through unknown mechanisms. Here, we show that NAMPT restricts herpes simplex virus type 1 (HSV-1) replication by impeding the virion incorporation of viral proteins owing to its phosphoribosyl-hydrolase (phosphoribosylase) activity, which is independent of the role of NAMPT in NAD+ synthesis. Proteomics analysis of HSV-1-infected cells identifies phosphoribosylated viral structural proteins, particularly glycoproteins and tegument proteins, which are de-phosphoribosylated by NAMPT in vitro and in cells. Chimeric and recombinant HSV-1 carrying phosphoribosylation-resistant mutations show that phosphoribosylation promotes the incorporation of structural proteins into HSV-1 virions and subsequent virus entry. Loss of NAMPT renders mice highly susceptible to HSV-1 infection. Our work describes an additional enzymatic activity of a metabolic enzyme in viral infection and host defence, offering a system to interrogate the roles of protein phosphoribosylation in metazoans. The NAD+ synthesis enzyme NAMPT is shown to possess additional enzymatic activity as a phosphoribosylase, which restricts the virion incorporation of viral proteins and underpins its antiviral effect","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"6 12","pages":"2300-2318"},"PeriodicalIF":18.9,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142678635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mis-adaptations may lead to seasonal patterns in several psychiatric disorders, but we know little regarding the underlying mechanisms. Our previous work identified two variants in the human circadian clock gene PERIOD3 (PER3), that is, P415A and H417R, which are associated with winter depression, but whether and how these variants lead to the disorder remain to be characterized. Here we find that male mice carrying human P415A and H417R display winter depression-like behaviours that are caused by the actions of P415A and H417R in the adrenal gland. Systemic corticosterone level is downregulated in adaptation to shortening of day length, while P415A and H417R eliminate this downregulation by increasing corticosterone synthesis. Enhanced glucocorticoid signalling represses the transcription of Tph2, which encodes the rate-limiting enzyme of serotonin synthesis, leading to increased depression-like behaviours. Taken together, our findings unveil a mechanism according to which human variants contribute to seasonal mood traits. The authors show how genetic variants of the human circadian clock gene PER3 are related to winter depression. In mice, under shorter light exposure, such variants enhance glucocorticoid signalling, inhibiting serotonin production and leading to depression-like behaviours.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"6 12","pages":"2267-2280"},"PeriodicalIF":18.9,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142597982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we show that capillaries in the diabetic mouse brain in both sexes are prone to stalling, with blocks consisting primarily of erythrocytes in branches off ascending venules. Screening for circulating inflammatory cytokines revealed persistently high levels of interleukin-10 (IL-10) in diabetic mice. Contrary to expectation, stimulating IL-10 signalling increased capillary obstruction, whereas inhibiting IL-10 receptors with neutralizing antibodies or endothelial specific knockdown in diabetic mice reversed these impairments. Chronic treatment of diabetic mice with IL-10 receptor neutralizing antibodies improved cerebral blood flow, increased capillary flux and diameter, downregulated haemostasis and cell adhesion-related gene expression, and reversed cognitive deficits. These data suggest that IL-10 signalling has an unexpected pathogenic role in cerebral microcirculatory defects and cognitive impairment associated with type 1 diabetes. Interleukin-10 promotes the formation of microcirculatory defects in the brain associated with cognitive impairment in a mouse model of type 1 diabetes.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"6 11","pages":"2082-2099"},"PeriodicalIF":18.9,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s42255-024-01159-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142574461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
