In the context of cancer, however, Tregs promote immune evasion and tumor progression, particularly through their unique adaptations within the tumor microenvironment (TME). Recent research has emphasized how metabolic characteristics shape Treg activation, migration, and immunosuppressive function, revealing the impact of metabolic pathways on Treg fitness in homeostasis and within the TME. In this review, we first provide an overview of Tregs in cancer immunology, discussing their immunosuppressive roles and properties specific to the TME. We then examine the metabolic requirements for Treg activation and migration under normal conditions, followed by a discussion of how hypoxia, lactate accumulation, nutrient limitation, oxidative stress, and other TME-specific factors alter Treg metabolism and contribute to cancer immune evasion. Finally, we explore therapeutic strategies that target Treg metabolism within the TME, including pharmacological modulation of specific metabolic pathways to diminish Treg-mediated immunosuppression. Thus, we could suggest future directions and clinical implications for Treg-targeted metabolic modulation as a complementary approach in cancer treatment, setting the stage for novel strategies in immunotherapy.","PeriodicalId":13307,"journal":{"name":"Immune Network","volume":"25 1","pages":"e13"},"PeriodicalIF":4.3,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896657/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explores the extensive range of macrophage activities within adipose and liver tissues, emphasizing their contribution to the pathogenesis and progression of obesity and its related metabolic dysfunction-associated steatotic liver disease (MASLD). In the context of obesity, macrophages respond adaptively to lipid overloads and inflammatory cues in adipose tissue, profoundly influencing insulin resistance and metabolic homeostasis. Concurrently, their role in the liver extends to moderating inflammation and orchestrating fibrotic responses, integral to the development of MASLD. Highlighting the spectrum of macrophage phenotypes across these metabolic landscapes, we summarize their diverse roles in linking inflammatory processes with metabolic functions. This review advocates for a deeper understanding of macrophage subsets in metabolic tissues, proposing targeted research to harness their therapeutic potential in mitigating MASLD and other metabolic disorders.","PeriodicalId":13307,"journal":{"name":"Immune Network","volume":"25 1","pages":"e12"},"PeriodicalIF":4.3,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896663/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alveolar macrophages (AMs), the tissue-resident macrophages (TRMs) of the lung, are particularly dependent on mitochondria-driven oxidative phosphorylation (OXPHOS) to support their functions and maintain homeostasis. However, the specific genes and pathways that regulate OXPHOS in AMs remain unclear. In this study, we investigated the role of CR6-interacting factor 1 (CRIF1), a mitochondrial regulator, as a key factor that specifically modulates the metabolic fitness and maintenance of AMs. Using single-cell RNA sequencing and transcriptomic analyses, we found CRIF1 to be highly expressed in AMs compared to TRMs from other tissues, correlating with enhanced OXPHOS activity. Genetic ablation of Crif1 in macrophages resulted in a marked reduction in AM populations exclusively in the lung, while other TRM populations were unaffected. CRIF1-deficient AMs exhibited an altered metabolic profile, including impaired mitochondrial function, increased glycolysis, and aberrant lipid accumulation. These findings underscore the essential role of CRIF1 in regulating mitochondrial functions and metabolic fitness in AMs, distinguishing it from broader mitochondrial regulators like mitochondrial transcription factor A, which operates across multiple TRM populations. Our study provides critical insights into the tissue-specific regulation of macrophage metabolism and suggests potential therapeutic avenues for lung diseases associated with AM dysfunction.","PeriodicalId":13307,"journal":{"name":"Immune Network","volume":"25 1","pages":"e9"},"PeriodicalIF":4.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896662/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examine the complex journey of AAAs from dietary intake through intestinal absorption and metabolic transformation, highlighting the crucial role of host-microbe metabolic networks in generating diverse immunomodulatory compounds. This review provides a unique integrative perspective by mapping the molecular mechanisms through which these metabolites orchestrate immune responses. Through detailed analysis of metabolite-receptor and metabolite-transporter interactions, we reveal how specific molecular recognition drives cell type-specific immune responses. Our comprehensive examination of signaling networks-from membrane receptor engagement to nuclear receptor activation to post-translational modifications- demonstrates how the same metabolite can elicit distinct functional outcomes in different immune cell populations. The context-dependent nature of these molecular interactions presents both challenges and opportunities for therapeutic development, particularly in inflammatory conditions where metabolite signaling pathways are dysregulated. Understanding the complexity of these regulatory networks and remaining knowledge gaps is fundamental for advancing metabolite-based therapeutic strategies in immune-mediated disorders.","PeriodicalId":13307,"journal":{"name":"Immune Network","volume":"25 1","pages":"e10"},"PeriodicalIF":4.3,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896664/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As tissue-resident cells, ILCs dynamically respond to local environmental cues, with tissue-derived metabolites such as short-chain fatty acids and amino acids directly modulating their effector functions. The metabolic states of ILC subsets-ILC1, ILC2, and ILC3-are closely linked to their ability to produce cytokines, sustain survival, and drive proliferation. This review provides a comprehensive analysis of how key metabolic pathways, including glycolysis, oxidative phosphorylation, and fatty acid oxidation, influence ILC activation and function. Furthermore, we explore the complex interactions between these metabolic pathways and tissue-specific metabolites, which can shape ILC-mediated immune responses in health and disease. Understanding these interactions reveals new insights into the pathogenesis of conditions such as asthma, inflammatory bowel disease, and cancer. A deeper understanding of these mechanisms may not only advance our knowledge of disease pathogenesis but also lead to the development of novel therapeutic strategies targeting metabolic pathways in ILCs to treat tissue-specific immune disorders.","PeriodicalId":13307,"journal":{"name":"Immune Network","volume":"25 1","pages":"e3"},"PeriodicalIF":4.3,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11896661/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143614805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
