Defects in this process result in proteinuria, one of the most frequently used biomarkers of kidney disease. Filtered proteins enter proximal tubules via receptor-mediated endocytosis and are processed within a highly developed apical endo-lysosomal system (ELS). Proteinuria is a strong risk factor for chronic kidney disease progression and genetic disorders of the ELS cause hereditary kidney diseases, so deepening understanding of how the proximal tubule handles proteins is crucial for translational nephrology. Moreover, the ELS is both an entry point for nephrotoxins that induce tubular damage and a target for novel therapies to prevent it. Cutting-edge research techniques, such as functional intravital imaging and computational modelling, are shedding light on spatial and integrative aspects of renal tubular protein processing in vivo, how these are altered under pathological conditions and the consequences for other tubular functions. These insights have potentially important implications for understanding the origins of systemic complications arising in proteinuric states, and might lead to the development of new ways of monitoring and treating kidney diseases. The kidney tubules have a crucial role in homeostasis as they modify and regulate the kidney filtrate. This Review examines current data on how filtered proteins are processed along the kidney tubule, including evidence from defects in the endo-lysosomal system, and their therapeutic implications.","PeriodicalId":19059,"journal":{"name":"Nature Reviews Nephrology","volume":"21 4","pages":"241-252"},"PeriodicalIF":28.6,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929477","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}

However, in the past two decades, research has shown that these sensory receptors also regulate physiological processes in a variety of non-sensory tissues. Although ORs, taste receptors and opsins have all been shown to have physiological roles beyond their traditional locations, most work in the kidney has focused on ORs. To date, renal ORs have been shown to have roles in blood pressure regulation (OLFR78 and OLFR558) and glucose homeostasis (OLFR1393). However, sensory receptors remain drastically understudied outside of traditional sensory systems, in part because of inherent challenges in studying these receptors. Increased knowledge of the physiological and pathophysiological roles of sensory receptors has the potential to substantially improve understanding of the function of numerous organs and systems, including the kidney. In addition, most sensory receptors are G protein-coupled receptors, which are considered to be the most druggable class of proteins, and thus could potentially be exploited as future therapeutic targets. Sensory receptors in non-sensory organs respond to chemical stimuli, initiate signalling cascades and have important roles in cell biology and physiology. Here, the authors discuss key examples of sensory receptors with physiological roles in the kidney and other tissues.","PeriodicalId":19059,"journal":{"name":"Nature Reviews Nephrology","volume":"21 4","pages":"253-263"},"PeriodicalIF":28.6,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916846","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}
