Abstract
Cancers can avoid immune-mediated elimination by acquiring traits that disrupt antitumour immunity. These mechanisms of immune evasion are selected and reinforced during tumour evolution under immune pressure. Some immunogenic subclones are effectively eliminated by antitumour T cell responses (a process known as immunoediting), which results in a clonally selected tumour. Other cancer cells arise to resist immunoediting, which leads to a tumour that includes several distinct cancer cell populations (referred to as intratumour heterogeneity (ITH)). Tumours with high ITH are associated with poor patient outcomes and a lack of responsiveness to immune checkpoint blockade therapy. In this Review, we discuss the different ways that cancer cells evade the immune system and how these mechanisms impact immunoediting and tumour evolution. We also describe how subclonal antigen presentation in tumours with high ITH can result in immune evasion.
期刊介绍：
Nature Reviews Immunology is a journal that provides comprehensive coverage of all areas of immunology, including fundamental mechanisms and applied aspects. It has two international standard serial numbers (ISSN): 1474-1733 for print and 1474-1741 for online. In addition to review articles, the journal also features recent developments and new primary papers in the field, as well as reflections on influential people, papers, and events in the development of immunology. The subjects covered by Nature Reviews Immunology include allergy and asthma, autoimmunity, antigen processing and presentation, apoptosis and cell death, chemokines and chemokine receptors, cytokines and cytokine receptors, development and function of cells of the immune system, haematopoiesis, infection and immunity, immunotherapy, innate immunity, mucosal immunology and the microbiota, regulation of the immune response, signalling in the immune system, transplantation, tumour immunology and immunotherapy, and vaccine development.
