Tumor metabolism, however, has largely been studied on whole tumors or cancer cells and the metabolism of infiltrating immune cells remains poorly understood. It is now clear from a range of analyses and metabolite rescue studies that metabolic adaptations to the tumor microenvironment (TME) directly impede T-cell and macrophage effector functions. The drivers of metabolic adaptation to the TME and metabolic immune suppression include depletion of essential nutrients, accumulation of waste products or immune suppression metabolites, and metabolic signaling through altered posttranslational modifications. Each infiltrating immune cell subset differs, however, with specific metabolic requirements and adaptations that can be maladaptive for antitumor immunity. Here, we review T-cell and macrophage adaptation and metabolic immune suppression in solid tumors. Ultimately, understanding and addressing these challenges will improve cancer immunotherapy and adoptive chimeric antigen receptor T-cell therapies.","PeriodicalId":10452,"journal":{"name":"Cold Spring Harbor perspectives in medicine","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140025290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A nearly ubiquitous feature of cancer cells is their capacity to grow independent of such signals, in an uncontrolled, cell-intrinsic manner. This property arises due to the frequent oncogenic activation of core growth factor signaling pathway components, including receptor tyrosine kinases, PI3K-AKT, RAS-RAF, mTORC1, and MYC, leading to the aberrant propagation of pro-growth signals independent of exogenous growth factors. The growth of both normal and cancer cells requires the acquisition of nutrients and their anabolic conversion to the primary macromolecules underlying biomass production (protein, nucleic acids, and lipids). The core growth factor signaling pathways exert tight regulation of these metabolic processes and the oncogenic activation of these pathways drive the key metabolic properties of cancer cells and tumors. Here, we review the molecular mechanisms through which these growth signaling pathways control and coordinate cancer metabolism.","PeriodicalId":10452,"journal":{"name":"Cold Spring Harbor perspectives in medicine","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140025450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Almost every component of the immune system plays a role in enabling or inhibiting breast tumor growth. Building on early seminal work showing the involvement of T cells and macrophages in controlling breast cancer progression and metastasis, single-cell genomics and spatial proteomics approaches have recently expanded our view of the TIME. In this article, we provide a detailed description of the immune response against breast cancer and examine its heterogeneity in disease subtypes. We discuss preclinical models that enable dissecting the mechanisms responsible for tumor clearance or immune evasion and draw parallels and distinctions between human disease and murine counterparts.
