Abstract

Pancreatic cancer (PC) is a highly malignant tumour of the digestive system with poor therapeutic response and low survival rates. Immunotherapy has rapidly developed in recent years and has achieved significant outcomes in numerous malignant neoplasms. However, responses to immunotherapy in PC are rare, and the immunosuppressive and desmoplastic tumour microenvironment (TME) significantly hinders their efficacy in PC. Tumour-associated neutrophils (TANs) play a crucial role in the PC microenvironment and exert a profound influence on PC immunotherapy by establishing a robust stromal shelter and restraining immune cells to assist PC cells in immune escape, which may subvert the current status of PC immunotherapy. The present review aims to offer a comprehensive summary of the latest progress in understanding the involvement of TANs in PC desmoplastic and immunosuppressive functions and to emphasise the potential therapeutic implications of focusing on TANs in the immunotherapy of this deleterious disease. Finally, we provide an outlook for the future use of TANs in PC immunotherapy.

肿瘤相关中性粒细胞：胰腺癌免疫疗法的潜在治疗目标

胰腺癌（PC）是一种高度恶性的消化系统肿瘤，治疗反应差，存活率低。近年来，免疫疗法迅速发展，在众多恶性肿瘤中取得了显著疗效。然而，免疫疗法在 PC 中的反应非常罕见，免疫抑制和去肿瘤微环境（TME）极大地阻碍了免疫疗法在 PC 中的疗效。肿瘤相关中性粒细胞（TANs）在PC微环境中起着至关重要的作用，通过建立稳固的基质庇护所和抑制免疫细胞来协助PC细胞进行免疫逃逸，从而对PC免疫疗法产生深远影响，这可能会颠覆PC免疫疗法的现状。本综述旨在全面总结人们在了解 TANs 参与 PC 去瘤和免疫抑制功能方面取得的最新进展，并强调在这种有害疾病的免疫疗法中关注 TANs 的潜在治疗意义。最后，我们对 TANs 未来在 PC 免疫疗法中的应用进行了展望。

期刊介绍： Immunology is one of the longest-established immunology journals and is recognised as one of the leading journals in its field. We have global representation in authors, editors and reviewers. Immunology publishes papers describing original findings in all areas of cellular and molecular immunology. High-quality original articles describing mechanistic insights into fundamental aspects of the immune system are welcome. Topics of interest to the journal include: immune cell development, cancer immunology, systems immunology/omics and informatics, inflammation, immunometabolism, immunology of infection, microbiota and immunity, mucosal immunology, and neuroimmunology. The journal also publishes commissioned review articles on subjects of topical interest to immunologists, and commissions in-depth review series: themed sets of review articles which take a 360° view of select topics at the heart of immunological research.
