Immune checkpoint blockade therapy has revolutionized the treatment of metastatic and solid tumours, achieving durable responses in a subset of patients. However, most patients do not respond to immune checkpoint blockade, underscoring the critical need to better understand the determinants of therapeutic efficacy. A key obstacle to effective antitumour immune responses is the abnormal structure and function of tumour-associated blood vessels, which impede immune cell infiltration and contribute to the development of an immunosuppressive tumour microenvironment. Current research highlights the inverse correlation between angiogenesis and immune activity within the tumour microenvironment. In this Review, we discuss tumour angiogenesis in the context of tumour immunity, examining how this affects tumour progression and immunotherapy outcomes. We examine the molecular mechanisms underlying the crosstalk between angiogenesis and tumour immunity and discuss emerging anti-angiogenic regulators that hold potential for combination therapies. By integrating insights from preclinical and clinical studies, we outline future research directions to address current challenges and optimize cancer treatment strategies through combined anti-angiogenic and immunotherapeutic approaches. Tumour-associated blood vessels are abnormal in structure and function, and this can limit immune cell infiltration into tumours and contribute to the immunosuppressive tumour microenvironment. This Review highlights how tumour angiogenesis impacts antitumour immunity and explains why combining anti-angiogenic strategies with immunotherapies could improve clinical outcomes for patients with cancer.
免疫检查点阻断疗法彻底改变了转移性肿瘤和实体瘤的治疗,在一部分患者中实现了持久的反应。然而,大多数患者对免疫检查点阻断没有反应,这强调了更好地了解治疗效果决定因素的迫切需要。有效抗肿瘤免疫应答的一个关键障碍是肿瘤相关血管的结构和功能异常,这阻碍了免疫细胞的浸润,并促进了免疫抑制肿瘤微环境的发展。目前的研究强调了肿瘤微环境中血管生成和免疫活性之间的负相关关系。在这篇综述中,我们在肿瘤免疫的背景下讨论肿瘤血管生成,研究它如何影响肿瘤进展和免疫治疗结果。我们研究了血管生成和肿瘤免疫之间串扰的分子机制,并讨论了新出现的抗血管生成调节因子,这些调节因子具有联合治疗的潜力。通过整合临床前和临床研究的见解,我们概述了未来的研究方向,以解决当前的挑战,并通过联合抗血管生成和免疫治疗方法优化癌症治疗策略。

Defects in antigen processing and presentation: mechanisms, immune evasion and implications for cancer vaccine development 抗原加工和呈递缺陷:机制、免疫逃避和对癌症疫苗开发的影响

Human tumour cells express mutated and non-mutated proteins that can be processed and presented by these cells as peptides bound to human leukocyte antigen (HLA). Some of these peptides are recognized by cognate T cell receptors as ‘non-self’, leading to specific killing of tumour cells by T cells. This process is fundamental to the success of cancer immunotherapy, which exploits the ability of the immune system to eliminate transformed cells. Mutated antigens (neoantigens) have been implicated in the remarkable therapeutic efficacy of immune checkpoint inhibitors (ICIs), which boost endogenous antitumour immune responses. In recent years, the combination of ICIs with personalized cancer vaccines that target neoantigens and other tumour-specific antigens has emerged as a new therapeutic strategy. However, the robust immune pressure that ICIs exert on cancer cells inevitably amplifies the phenomenon of immune editing, which can allow cancer cells to develop resistance mechanisms that subvert surveillance by the immune system. Diminished antigenicity can be due to defects in the antigen processing and presentation machinery, such as HLA-I/II loss of heterozygosity and loss of functional β2-microglobulin. This poses a considerable challenge for combination therapies that include ICIs and for the design of cancer-specific vaccines. Effective tumour-specific T cell immunity — and the success of cancer immunotherapies — relies on the presentation of antigens via human leukocyte antigen (HLA) molecules. In this Review, Bassani-Sternberg and Huber explore recent advances in understanding the repertoire of tumour-specific antigens, as well as how disruptions in antigen processing and presentation contribute to immune evasion and resistance to immune checkpoint blockade. The authors also highlight how these insights can inform the design of personalized neoantigen-based vaccines and combination therapies aimed at outpacing tumour immunoediting.
人类肿瘤细胞表达突变和非突变的蛋白质,这些蛋白质可以被这些细胞加工并作为与人类白细胞抗原(HLA)结合的肽呈递。其中一些肽被同源T细胞受体识别为“非自我”,导致T细胞特异性杀死肿瘤细胞。这个过程是癌症免疫疗法成功的基础,它利用免疫系统的能力来消除转化细胞。突变抗原(新抗原)与免疫检查点抑制剂(ICIs)显著的治疗效果有关,ICIs可以增强内源性抗肿瘤免疫反应。近年来,ICIs与针对新抗原和其他肿瘤特异性抗原的个性化癌症疫苗的结合已成为一种新的治疗策略。然而,ICIs对癌细胞施加的强大免疫压力不可避免地放大了免疫编辑现象,这可能使癌细胞形成抵抗机制,从而破坏免疫系统的监视。抗原性的降低可能是由于抗原加工和呈递机制的缺陷,如hla - 1 /II杂合性的丧失和功能性β2微球蛋白的丧失。这对包括ICIs在内的联合疗法和癌症特异性疫苗的设计提出了相当大的挑战。

In 1975, Köhler and Milstein invented hybridoma technology for the generation of murine monoclonal antibodies with predetermined antigen-binding specificity. The transformative impact of monoclonal antibodies is demonstrated by their ubiquitous use as biomedical research reagents and the worldwide approval of at least 212 antibody therapeutics with tens of millions of patients treated to date. Advances in antibody technologies, such as humanization and robust methods for human antibody generation, mitigated the major limitations of murine antibodies as therapeutics. These technologies, combined with progress in biomanufacturing, helped to launch this modern era of antibody therapeutics. Beyond IgG, antibody therapeutics have blossomed into multiple alternative formats, including bispecific antibodies and antibody–drug conjugates. Additionally, antibody fragments have been developed as stand-alone therapeutics and to target cell therapies, notably chimeric antigen receptor T cells. These advances in antibody technologies, plus innovation enabling subcutaneous delivery, have improved the therapeutic benefits and convenience of antibody treatment for many patients. This concept is illustrated here by multiple generations of antibody therapeutics for human epidermal growth factor receptor 2 (HER2)+ cancers and B cell-targeted therapies for haematological cancers and immunological diseases. Finally, we opine briefly on some of the many promising future directions with antibody therapeutics, including the application of artificial intelligence for antibody identification and multi-parameter optimization. Fifty years ago, Köhler and Milstein introduced the world to hybridoma technology for the generation of monoclonal antibodies. Scientists have subsequently built upon this seminal discovery to develop antibody-based therapies for numerous diseases, with millions of patients benefiting from such drugs. To mark 50 years of monoclonal antibodies, this Review from Chan, Martyn and Carter provides an overview of how antibody engineering strategies have continued to improve antibody-based therapeutics, chiefly focusing on antibody-mediated targeting of B cells and also human epidermal growth factor receptor 2 (HER2)+ cancers. The authors also highlight the promise of emerging tools, including artificial intelligence, for development of the next generation of antibody-based therapeutics.
1975年,Köhler和Milstein发明了杂交瘤技术,用于产生具有预定抗原结合特异性的小鼠单克隆抗体。单克隆抗体作为生物医学研究试剂的广泛使用,以及迄今为止全球至少批准了212种抗体治疗方法,治疗了数千万患者,证明了单克隆抗体的变革性影响。抗体技术的进步,如人源化和人类抗体生成的稳健方法,减轻了小鼠抗体作为治疗手段的主要局限性。这些技术与生物制造的进步相结合,帮助开启了抗体治疗的现代时代。除了IgG,抗体疗法已经发展成多种形式,包括双特异性抗体和抗体-药物偶联物。此外,抗体片段已被开发为独立治疗和靶向细胞治疗,特别是嵌合抗原受体T细胞。抗体技术的这些进步,加上能够皮下递送的创新,提高了许多患者的治疗效果和抗体治疗的便利性。针对人类表皮生长因子受体2 (HER2)阳性癌症的多代抗体疗法和针对血液学癌症和免疫疾病的B细胞靶向疗法说明了这一概念。最后,我们简要地展望了抗体治疗的未来发展方向,包括人工智能在抗体鉴定和多参数优化方面的应用。

The cell-autonomous innate immune system is responsible for sensing and mitigating viral infection at the level of individual cells. Many of the mechanisms used by the cell-autonomous innate immune system in eukaryotic cells are ancient and have evolutionary roots in bacterial systems that defend against phage infection. Studies from recent years have shown that modification of the free nucleotide pool is central to many of these conserved immune mechanisms. In this Review, we explain how immune pathways manipulate the available pool of nucleotides to deprive viruses of molecules essential for their replication, how immune proteins chemically modify nucleotides to generate immune signalling molecules, and how cell-autonomous innate immune mechanisms produce altered nucleotides that poison viral replication. We also discuss the mechanisms used by viruses to antagonize nucleotide-based immunity. Finally, we explore the evolutionary logic of using nucleotides as building blocks for immune responses. Modification of the nucleotide pool is emerging as key to innate immunity in animals, plants and bacteria. This Review explains how immune pathways conserved from bacteria to humans manipulate the nucleotide pool to block viral replication and produce immune signalling molecules.

Stem cells maintain tissue architecture by replacing differentiated cells at steady state and upon injury. Implementing this cornerstone role requires protection of stem cells from pathogens and from the toxic effects of immune system activation. However, the pro-inflammatory innate immune mechanisms that protect differentiated cells from infection are poorly functional in stem cells. Instead, stem cells employ other specific defence mechanisms, such as antiviral RNA interference. At steady state, the proliferation and differentiation of tissue stem cells is regulated by multiple cell types, including immune cells. Following sterile tissue injury or during infection, the immune response — in addition to controlling pathogens and clearing cell debris — orchestrates tissue repair by fine-tuning stem cell activity, through direct cell–cell contacts and via inflammatory mediators such as cytokines. There is thus stem–immune cross-talk that is fundamental to the maintenance of tissue homeostasis. Inflammageing, which is defined as the age-driven elevation of inflammation and is associated with an altered immune cell composition, profoundly affects this stem–immune cross-talk, impacting the ability to repair tissues and participating in ageing of the whole organism. This Review by Poirier highlights the intrinsic mechanisms that protect stem cells from infection. The author also explains how stem cell populations in different tissue sites respond to infection or injury to protect tissue integrity, and the impact of inflammageing on these processes.
干细胞在稳态和损伤时通过替代分化细胞维持组织结构。实现这一基石作用需要保护干细胞免受病原体和免疫系统激活的毒性影响。然而,保护分化细胞免受感染的促炎性先天免疫机制在干细胞中功能不佳。相反,干细胞采用其他特定的防御机制,如抗病毒RNA干扰。在稳定状态下,组织干细胞的增殖和分化受多种细胞类型的调控,包括免疫细胞。在无菌组织损伤或感染期间,除了控制病原体和清除细胞碎片外,免疫反应还通过直接的细胞间接触和细胞因子等炎症介质,通过微调干细胞活性来协调组织修复。因此,茎-免疫相互作用是维持组织稳态的基础。炎症被定义为年龄驱动的炎症升高,与免疫细胞组成的改变有关,它深刻地影响了这种干细胞-免疫的相互作用,影响了组织修复的能力,并参与了整个生物体的衰老。

The author also explains how stem cell populations in different tissue sites respond to infection or injury to protect tissue integrity, and the impact of inflammageing on these processes.","PeriodicalId":19049,"journal":{"name":"Nature Reviews Immunology","volume":"25 12","pages":"900-911"},"PeriodicalIF":60.9,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701339","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}
