    Copper is an essential trace element with inherent redox properties and fundamental roles in a diverse range of biological processes; therefore, maintaining copper homeostasis is crucial. In this Review, the authors discuss new insights into the mechanisms by which disrupted copper homeostasis contributes to tumour initiation and development, including the recently defined concepts of cuproplasia (copper-dependent cell growth and proliferation) and cuproptosis (a mitochondrial pathway of cell death triggered by excessive copper exposure). They also discuss potential strategies to exploit cuproplasia and cuproptosis for the treatment of cancer.

    Dendritic cells (DCs) are antigen-presenting cells that function at the interface between innate and adaptive immunity, thereby acting as key mediators of antitumour immune responses and immunotherapy efficacy. In this Review, the authors outline the emerging complexity of intratumoural DC states that is being revealed through single-cell analyses as well as the contributions of different DC subsets to anticancer immunity and the activity of immune-checkpoint inhibitors. The authors also discuss advances in the development of DC-based cancer therapies and considerations for their potential combination with other anticancer therapies.

    The TAM (TYRO3, AXL and MERTK) family receptor tyrosine kinases (RTKs) have diverse cancer-promoting functions in malignant cells as well as immune cells and other cell types in the tumour microenvironment, presenting an attractive opportunity for both direct and immune-mediated therapeutic activity manifest through inhibition of a single target. Accordingly, a variety of agents designed to selectively target TAM RTKs are entering clinical testing. This Review provides an essential guide to the TAM RTKs for clinicians. The authors comprehensively review the various roles of TAM RTKs in cancer, the evidence supporting their potential as therapeutic targets, and the translational development of TAM-targeted agents as cancer treatments.

    Antibodies targeting PD-1 or its ligand PD-L1 have revolutionized cancer therapy. Increased understanding of the mechanisms regulating PD-L1 has revealed links with several important oncogenic signalling pathways. Herein, the authors review the transcriptional, post-transcriptional and translational regulation of PD-L1 expression in cancers as well as the diverse post-translational modifications, including phosphorylation, palmitoylation, glycosylation, acetylation and ubiquitination, that affect PD-L1 stability and activity. They also discuss the possibility to simultaneously target key oncogenic pathways and modulate PD-L1 expression using small-molecule agents, which have potential advantages over or might synergize with anti-PD-1/PD-L1 antibodies.

    Two recent studies addressed the functional properties and clinical significance of tumour antigen-specific effector T cells in human melanomas and lung carcinomas using single-cell strategies. Herein, we discuss their findings, which expand our understanding of T cell alterations in the tumour microenvironment and demonstrate that CD8+ T cell exhaustion is mediated by exposure to tumour cell-specific antigens and is associated with a tissue-resident memory phenotype.

    Chimeric antigen receptor (CAR) T cell therapies are generating substantial excitement and have been approved for the treatment of various haematological malignancies. All approved CARs consist of an extracellular antigen-binding domain linked to an intracellular region containing a costimulatory domain and a T cell activation domain. A key question is whether the CD28-derived and 4-1BB-derived costimulatory domains used in current commercial CAR T cell products are associated with different cellular and clinical effects. Herein, Cappell and Kochenderfer provide an overview of CD28 and 4-1BB costimulatory pathways and compare the outcomes observed in preclinical and clinical studies with CARs incorporating either costimulatory domain.

    An unfavourable gut bacterial composition has been shown to reduce the likelihood of clinical benefit from immune-checkpoint inhibitors (ICIs). The results of two first-in-human studies of faecal microbiota transplantation in patients with melanoma refractory to anti-PD-1 antibodies validate preclinical evidence that this approach can improve the gut microbiota and overcome resistance to ICIs; however, many questions remain.

    Tumour budding is hypothesized to reflect the invasive and metastatic capacities of cancers and is accordingly associated with unfavourable patient outcomes. Herein, Lugli and colleagues describe the pathobiological characteristics of this phenomenon, including its associations with epithelial–mesenchymal transition and features of the tumour microenvironment, and review the evidence demonstrating the value of tumour budding as a prognostic biomarker across various solid cancers.

    Signalling induced by extracellular adenosine (eADO) can suppress antitumour immunity through multiple mechanisms. Herein, the authors review the pathophysiological functions of eADO in cancer and the related prognostic implications. They discuss the associated opportunities for eADO pathway-targeted immunotherapy, highlighting potential limitations and the scope for combination and biomarker-based strategies. The data emerging from oncology clinical trials of the diverse range of therapies that have been developed to target the eADO signalling pathway are also described.

    The use of bispecific antibodies to engage cells of the immune system that are cytotoxic to cancer cells is a major focus of cancer immunotherapy, with approvals for the treatment of acute lymphoblastic leukaemia. Here, the authors review the clinical results obtained with bispecific antibodies to date. They also discuss the challenges associated with this therapeutic approach and the proposed solutions aimed at preventing or minimizing toxicities, countering immune escape and broadening the indications for these treatments.

    Surgery remains a key pillar of cancer therapy, particular for those with curable, localized disease. The immediate perioperative period (days before and after surgery) is associated with various psychological and physiological stresses and associated factors, including inflammatory mediators, that might promote cancer progression and thus determine long-term outcomes. Herein, the authors present the hypothesis and supporting evidence that the use of certain types of immunotherapy, together with interventions to abrogate stress–inflammatory responses, in conjunction with surgery might improve the overall success of cancer treatment.

    As more patients with oncogene-driven non-small-cell lung cancer are treated with targeted therapies, they are joining forces online to form groups that provide support, education and advocacy focused on specific oncogenes. Herein, we discuss how the involvement of these groups in patient-partnered research can benefit both patients and lung cancer research.

    Chimeric antigen receptor (CAR) T cell therapy, the first approved therapeutic approach with a genetic engineering component, holds substantial promise in the treatment of a range of cancers but is nevertheless limited by various challenges, including toxicities, intrinsic and acquired resistance mechanisms, and manufacturing issues. In this Review, the authors describe the innovative approaches to the engineering of CAR T cell products that are providing solutions to these challenges and therefore have the potential to considerably improve the safety and effectiveness of treatment.

    Cancer stem cells (CSCs) are implicated in cancer development, progression and resistance to treatment; therefore, the signalling pathways that mediate the CSC phenotype are attractive therapeutic targets. In this Review, the authors provide an update on the progress in targeting the Notch, WNT, Hedgehog and Hippo signalling pathways. Additionally, they discuss the interactions of CSCs with the immune system, the roles of CSC-related signalling pathways in immune cells and novel approaches to CSC-directed immunotherapy.

    The adoptive transfer of T cells expressing a chimeric antigen receptor (CAR) is an effective therapy for patients with relapsed or refractory CD19+ B cell malignancies, but can cause life-threatening toxicities. Herein we discuss a recent study suggesting that alterations to the design of anti-CD19 CARs can reduce cytokine release and the incidence of treatment-related complications.

    Patients with resectable solid tumours can harbour minimal residual disease (MRD) after initial treatment, which is a potential source for subsequent metastatic relapse. The interaction between disseminated tumour cells (DTCs) and the new microenvironment in which they reside determines whether DTCs remain dormant or progress into overt metastases. We highlight the promise of liquid biopsies to inform on MRD.

    According to the cancer stem cell (CSC) paradigm, a minor subpopulation of cancer cells with stem-cell properties predominantly underlies tumour progression, therapy resistance, and disease recurrence. Notably, epithelial-to-mesenchymal transition (EMT) is implicated in these processes, and CSCs typically show markers of EMT-programme activation. Herein, the authors outline our current understanding of the links between the EMT programme, the CSC phenotype, metastasis, and drug resistance, and discuss the potential for therapeutic targeting of these facets of tumour biology.

    Telomerase reverse transcriptase (TERT) is expressed constitutively in tumour cells throughout the evolution of many cancers; therefore, this potential tumour self-antigen has been an important target for anticancer vaccines over the past 10 years, but only modest benefits from this approach have been observed in clinical trials. In this Perspectives, Maurizio Zanetti reviews these studies, and highlights advances in our knowledge that warrant further development and refinement of TERT immunotherapy.

    Although dramatic changes in the delivery of radiation therapy have occurred, the impact of radiobiology on the clinic has been far less substantial. New advances are uncovering some of the mechanistic processes that underlie the differences between the tumour and host tissue characteristics. The authors of this Review focus on how these processes might be targeted to improve the outcome of radiotherapy for patients.

  • Review Article |

    Cancer stem cell (CSC) populations are increasingly recognized in most malignancies and are hypothesized to contribute to cancer proliferation, relapse, and metastasis. Thus, the highly conserved stem-cell signal transduction pathways involved in development and tissue homeostasis that are frequently active in CSCs represent prime targets for targeted therapies against this characteristically treatment-resistant and highly tumorigenic cell population. This Review provides a update on the clinical development of therapies targeting Wnt, Notch, and Hedgehog, three prominent stem-cell signalling pathways that are upregulated in CSCs.
