Available in PDF, EPUB and Kindle. Book excerpt: The clinical success of immune checkpoint blockers is a pivotal advancement for treating an increasing number of cancer types. However, immune checkpoint blockers still rarely induce complete remission and show little to no therapeutic efficacy in a significant percentage of cancer patients. Efforts are now underway to identify biomarkers that accurately predict which patients benefit from immune checkpoint blockers. Moreover, adaptive immune resistance can develop in tumors during treatment with immune checkpoint blockers. These adaptive resistance mechanisms in tumors might be disrupted by combining adjunctive immunotherapies, which could potentially improve the therapeutic efficacy of immune checkpoint blockers. This chapter discusses the mechanism of action of cytotoxic T lymphocyte antigen-4 (CTLA-4) and programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) immune checkpoint blockers and biomarkers that might predict clinical responses to these drugs. Lastly, ongoing research on mechanisms of tumor adaptive resistance could facilitate rationale design of adjunctive immunotherapies that can be synergistically combined with immune checkpoint blockers to more effectively treat cancer.

Download or read book Adaptive Immune Resistance in Cancer Therapy written by Lin Qi and published by Frontiers Media SA. This book was released on 2024-02-16 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adaptive immune resistance (AIR) mechanism refers to the various strategies employed by tumours to adapt and ultimately to overcome immune attack. The AIR mechanism was firstly identified in the selective induction of programmed cell death 1 ligand 1 (PDL1) by interferon gamma of tumors. The inhibition of adaptive immune resistance underlies the responses to PD-1 or PD-L1–blocking antibodies, and may have relevance for the development of other cancer immunotherapy strategies. Therefore, identifying specific AIR mechanisms is of great significance to develop novel drugs and enhance the efficacy of cancer treatment. In this research topic, we aim to generate a collection of articles that discuss the AIR mechanisms, the classification of AIRs, and the current and future cancer therapy strategies based on AIR. Of particular, these articles can focus on exploring the AIR mechanisms in different cancer types and further identify the association between AIR and tumour microenvironment (TME).

This book was released on 2019-12-27 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The immune system harbors great potential for controlling and eliminating tumors. Recent developments in the field of immuno-oncology has led to unprecedented clinical benefits for a broad spectrum of solid tumors. However, immunotherapy (IT) approaches currently have several limitations including (i) low response rate; (ii) development of resistance and (iii) causing severe immune-related adverse effects (IrAEs), which underline the importance of adequate patient selection. Importantly, IT holds promising synergistic potential when combined with standard-of-care chemotherapy, radiotherapy (RT) and anti-angiogenic therapy (AAT) as part of multi-modal oncologic treatment regimes. Published data suggest that there are potential synergy between RT and AAT, which ultimately could help potentiate the response to IT. However, the complex interactions between RT and IT and/or AAT remain poorly understood. Many research questions including optimal timing, scheduling and dosing, as well as patient selection and side effects of combined therapy approaches, remain to be addressed. This Research Topic aims to give a comprehensive overview of the current field with particular emphasis on the future outlook of RT and AAT as complementary approaches to improve IT in solid tumors.

Book excerpt: In this book, leading experts in cancer immunotherapy join forces to provide a comprehensive guide that sets out the main principles of oncoimmunology and examines the latest advances and their implications for clinical practice, focusing in particular on drugs with FDA/EMA approvals and breakthrough status. The aim is to deliver a landmark educational tool that will serve as the definitive reference for MD and PhD students while also meeting the needs of established researchers and healthcare professionals. Immunotherapy-based approaches are now inducing long-lasting clinical responses across multiple histological types of neoplasia, in previously difficult-to-treat metastatic cancers. The future challenges for oncologists are to understand and exploit the cellular and molecular components of complex immune networks, to optimize combinatorial regimens, to avoid immune-related side effects, and to plan immunomonitoring studies for biomarker discovery. The editors hope that this book will guide future and established health professionals toward the effective application of cancer immunology and immunotherapy and contribute significantly to further progress in the field.

Download or read book Cancer Immunotherapy written by Jenni Punt and published by Elsevier Inc. Chapters. This book was released on 2013-06-04 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once alerted by the innate immune system to the presence of a pathogen or a cellular abnormality, the adaptive immune system responds by activating and expanding antigen-specific B and T lymphocytes. This chapter focuses specifically on the activation and activities of T lymphocytes, which coordinate the adaptive immune response. We open with a description of where and how naïve T cells first encounter antigen. We then examine what factors influence the differentiation of helper CD4+ T lymphocytes into one of several effector subsets, each of which secretes a distinct subset of cytokines. We follow with a discussion of the origin and function of cytotoxic CD8+ T cells, the lymphocyte with the capacity to directly kill tumor cells. We close with a brief summary of the unique challenges that face the adaptive immune system when it tried to mount a response to a tumor.

This book was released on 2019-09-05 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, significant progress has been made in the clinical development and use of various types of cancer immunotherapy, all of which rely on the immune system to fight cancer. The majority of new cancer drug applications submitted to the Food and Drug Administration (FDA) are for immunotherapies or combinations involving immunotherapies. One type of immunotherapy is an immune checkpoint inhibitor. Cells in the human body have proteins that regulate the immune system response to foreign invaders (e.g., cancer cells, microorganisms). However, cancer cells can coopt these "checkpoint" proteins and thwart the immune system's ability to recognize and attack cancer cells. To help promote an immune response to cancer, researchers have developed immune checkpoint inhibitors that enable T-cells to recognize cancer cells as foreign and to prevent deactivation of an immune system response. To examine the challenges and opportunities to develop combination cancer therapies that include immune checkpoint inhibitors, the National Cancer Policy Forum held a workshop on July 16â€"17, 2018, in Washington, DC. This workshop convened stakeholders with a broad range of expertise, including cancer researchers, clinicians, patient advocates, and representatives from industry, academia, and government. This publication summarizes the presentations and discussions from the workshop.

Download or read book Understanding convergent evasion mechanisms in cancer and chronic infection Implications for immunotherapy written by Matthias Theobald and published by Frontiers Media SA. This book was released on 2024-06-04 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex interactions between the innate and adaptive immune systems function to recognize and clear pathogens or transformed cells, but inefficient interactions between these two systems can result in harmful immunologic responses including chronic infections and the development of cancer. Several hallmarks of dysfunctional adaptive immune responses often detected in tumors share specific features with ineffective immunity in chronic infections. The members of the micromilieu actively participate in the process of tumorigenesis or chronification of infection by modulating innate and adaptive immune system interactions leading e.g. to insufficient T cell responses. The best example is given by the acquisition of an “exhausted” state of cytotoxic CD8+ T cells (CTLs) responding to chronic infections or tumors that are associated with elevated expression of inhibitory receptors and impaired cytokine response. Targeting these major inhibitory pathways by immune checkpoint blockers represents a prime example of successful clinical translation of tumor-specific immunotherapies. Understanding the mechanisms behind (mal)adaptations of the immune system is crucial for achieving therapeutic benefits. The establishment and co-evolution of a dynamic microenvironment niche constituted by the recruitment of numerous cell types dampen immune responses and thus contribute to the development of neoplastic transformation as well as infection. Although there are examples of successful immunotherapeutic approaches (CAR-T cells, immune checkpoint inhibitors, or mRNA vaccination), a large percentage of patients with cancer or chronic infections still do not benefit from these therapies or develop severe immune-related adverse events. The reasons for these failures are not well understood. A possible explanation might be that current immunotherapies target predominantly the effector arm of the immune system by trying to reactivate dysfunctional T cells, but do not sufficiently address the influence of the innate immune system and the contributions of the tumor microenvironment (TME) niche. The main problem we would like to address in this special issue is how inappropriate function of the innate immune system affects adaptive immunity and contributes to inefficient anti-cancer immunity and chronification of infections. The central goal is to provide a more precise understanding of the various (common and novel) immune evasion mechanisms in cancers and in chronic infections to obtain a detailed map of common and disease-specific immune escape checkpoints. To that aim, we want to compile a wide array of interdisciplinary studies exploring a comparative and multi-layered analysis of mechanisms responsible for inefficient immune responses, including novel approaches i.e. multi-omics or epigenetic signaling. We would also like to combine studies from different fields, including basic and clinical immunology, oncology, and virology/microbiology. We welcome the submission of Original Research, Review, Mini-Review, Methods, Case report, and Perspective articles that cover, but are not limited to the following topics: • Convergent mechanisms supporting immune escape in preclinical models (tumors and chronic infections) • Convergent evasion mechanisms mediated by tumor-infiltrating suppressive cells (Treg, MDSC, macro-phages, soluble mediators, signaling, metabolism, ...) • Convergent immune evasion mechanisms mediated by chronic infection (viral or parasite) • Novel strategies to modulate the TME by direct or indirect targeting of immune suppressor cells. • Approaches to enhance persistence and resilience of anticancer T cells • Combinatorial therapeutic strategies (mRNA, antibodies, immune checkpoint blockers …) that target convergent immune evasion mechanisms Manuscripts consisting solely of bioinformatics or computational analysis of public genomic or transcriptomic databases which are not accompanied by robust and relevant validation (clinical cohort or biological validation in vitro or in vivo) are out of scope for this topic.

Download or read book Anti tumor Activity of Cytotoxic Immune Cells Basic Research and Clinical Perspectives written by Malgorzata Firczuk and published by Frontiers Media SA. This book was released on 2024-05-24 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cytotoxic T lymphocytes (CTL) and natural killer (NK) cells are powerful effectors of antitumor immunity. CTL recognize tumor antigens presented by human leukocyte antigen (HLA) molecules with antigen-specific T cell receptors (TCR) and are the key effector cells of the adaptive immune response. In contrast, NK cells lack antigen-specific receptors and are regulated by the balance of signals from activating and inhibitory receptors. These two types of cells cooperate and complement each other in eliciting host immune response to cancer and mediating immune surveillance. Moreover, these cells play a crucial role in antitumor immunotherapy, including monoclonal antibodies (mAbs), bispecific T cell engagers (BiTe), as well as adoptive transfer of chimeric antigen receptor (CAR)-modified cytotoxic cells.

Download or read book Immunotherapy of Hepatocellular Carcinoma written by Tim F. Greten and published by Springer. This book was released on 2018-08-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book we provide insights into liver – cancer and immunology. Experts in the field provide an overview over fundamental immunological questions in liver cancer and tumorimmunology, which form the base for immune based approaches in HCC, which gain increasing interest in the community due to first promising results obtained in early clinical trials. Hepatocellular carcinoma (HCC) is the third most common cause of cancer related death in the United States. Treatment options are limited. Viral hepatitis is one of the major risk factors for HCC, which represents a typical “inflammation-induced” cancer. Immune-based treatment approaches have revolutionized oncology in recent years. Various treatment strategies have received FDA approval including dendritic cell vaccination, for prostate cancer as well as immune checkpoint inhibition targeting the CTLA4 or the PD1/PDL1 axis in melanoma, lung, and kidney cancer. Additionally, cell based therapies (adoptive T cell therapy, CAR T cells and TCR transduced T cells) have demonstrated significant efficacy in patients with B cell malignancies and melanoma. Immune checkpoint inhibitors in particular have generated enormous excitement across the entire field of oncology, providing a significant benefit to a minority of patients.
