Despite their overlap, current guidelines address portal hypertension and HCC separately, leading to suboptimal risk stratification and treatment selection. This Review proposes a stage-based, integrated approach to HCC management that incorporates the prognostic stages of cirrhosis and emphasizes clinically significant portal hypertension (CSPH) as a key stratifying factor in compensated cirrhosis. CSPH is associated with an increased risk of cirrhosis decompensation, and its presence often limits the feasibility of curative treatments such as surgical resection. Although CSPH is strictly defined as hepatic venous pressure gradient (HVPG) of ≥10 mmHg, non-invasive tools (liver stiffness and platelet count) have largely replaced HVPG in cirrhosis; in patients with HCC, emerging data suggest that these non-invasive tests are poised to replace HVPG and its traditional surrogates, imaging and endoscopy. We explore the management of both cirrhosis and HCC across all cirrhosis stages - compensated (with or without CSPH), decompensated, and further decompensated - in relation to all HCC stages (very early, early, intermediate and advanced). Future research should validate non-invasive CSPH assessment in HCC and support outcome trials stratified by cirrhosis and HCC stage to guide personalized therapy and improve outcomes.</p>","PeriodicalId":18793,"journal":{"name":"Nature Reviews Gastroenterology &Hepatology","volume":" ","pages":""},"PeriodicalIF":51.0,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840475","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}

Under homeostatic conditions, they control tissue integrity and maintain the epithelial barrier. In contrast to conventional αβ T cells, γδ T cells sense stress-induced cellular alterations and, therefore, can recognize transformed cells independently of MHC (HLA in humans) molecules. In colorectal cancer and hepatocellular carcinoma, γδ T cells constitute an important part of the antitumour immune response. However, there is evidence that γδ T cells can also promote tumorigenesis. In this Review, we present basic features of γδ T cells and their distribution and function in the context of the local immune response. We discuss the ligands and antigens recognized by circulating and tissue-resident human γδ T cells, as well as the functional diversity of γδ T cell subsets within tumour-infiltrating T cells in colorectal and liver cancer. Given their potent cytotoxic activity and HLA-independent mode of action, there is increasing interest in harnessing γδ T cells for application in cancer immunotherapy. We therefore discuss the current status and future challenges of using γδ T cells as an innovative immunotherapeutic strategy for gastrointestinal and liver cancer.","PeriodicalId":18793,"journal":{"name":"Nature Reviews Gastroenterology &Hepatology","volume":"25 1","pages":""},"PeriodicalIF":65.1,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147733823","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}

The durations of, and transitions between, these behavioural phases are driven by underlying interoceptive phenomena of hunger, satiation and satiety. The gut-brain axis regulates all eating phases, with the vagus nerve a primary conduit for interoceptive feedback about gut-derived mechanical and chemical cues. This Review explores the mechanisms governing each phase, focusing on how gut-derived signals are peripherally and centrally integrated to shape hunger, satiation and satiety, food preferences, and food-related learning. Chronic exposure to high-fat, high-sugar diets disrupts these mechanisms, driving a maladaptive state characterized by hyperphagia, food choice biases and habitual overeating. We examine the mechanisms underlying this maladaptive state, including vagal fibre remodelling, altered gene expression and leptin resistance, which can impair gut-brain communication, diminishing the brain's capacity to appropriately control eating behaviour and maintain energy balance. Emerging therapies, including glucagon-like peptide 1 receptor agonists, are effective in promoting weight loss but typically do not reverse the underlying causes of gut-brain axis dysfunction. By examining the mechanisms of gut-brain signalling, this Review highlights the vagus nerve as a key, yet underappreciated, target for obesity treatment.","PeriodicalId":18793,"journal":{"name":"Nature Reviews Gastroenterology &Hepatology","volume":"7 1","pages":""},"PeriodicalIF":65.1,"publicationDate":"2026-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147731480","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}

NADPH:cytochrome P450 oxidoreductase (CPR, encoded by POR), the essential electron donor for microsomal cytochrome P450 enzymes and other redox partners, orchestrates xenobiotic detoxification, lipid metabolism, steroid and bile acid biosynthesis, and redox balance - processes disrupted in MASLD. This Perspective examines emerging evidence from genetic, biochemical, transcriptomic and clinical studies that implicate CPR in the pathophysiology of MASLD, including its roles in lipid accumulation, oxidative stress, mitochondrial dysfunction, iron homeostasis, ferroptosis and inflammatory signalling. We discuss how CPR dysfunction, driven by genetic polymorphisms or metabolic stress, contributes to disease heterogeneity and progression. These insights highlight CPR as a relevant and potentially actionable regulator of hepatic metabolism. The current FDA approval of resmetirom, a thyroid hormone receptor-β agonist, which increases POR transcription levels, provides translational proof that restoring CPR-dependent pathways can ameliorate MASH with fibrosis. A deeper understanding of the multifaceted role of CPR could inform precision medicine strategies for this complex and widespread liver disease.","PeriodicalId":18793,"journal":{"name":"Nature Reviews Gastroenterology &Hepatology","volume":"22 1","pages":""},"PeriodicalIF":65.1,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147725638","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}

Clinical practice guidelines for adults typically recommend a uniform treatment approach, regardless of age-related considerations. However, different emphases might be needed for pregnant women, adults and the older age group (≥65 years of age). Moreover, metabolic health, and therefore liver health, are determined at a very early age and even in utero and infancy. Thus, the prevention and treatment of SLD should not be overlooked at these early life stages and should be specific for each stage of life. The life course approach is a comprehensive strategy that considers health needs across all stages of life, from infancy to older age.

Initially thought to be associated mainly with pernicious anaemia and limited to certain geographical areas, AIG is now recognized as a global disorder with a broad clinical spectrum, ranging from asymptomatic cases to gastrointestinal, haematological, neurological and gynaecological manifestations. The role of Helicobacter pylori in the development of AIG has been debated, with evidence suggesting that AIG might arise through distinct pathogenic pathways both related and unrelated to H. pylori infection. The risk of gastric adenocarcinoma in AIG has also been reassessed on the basis of studies exploring its natural history. Finally, novel insights have emerged regarding the characterization of 'potential AIG' and 'seronegative AIG', two distinct conditions that were previously overlooked.
