This book brings together the world’s leading authorities on tumor immunology. This book describes the basic immunology principles that form the foundation of understanding how the immune system recognizes and rejects tumor cells. The role of the innate and adaptive immune responses is discussed and the implications of these responses for the design of clinical strategies to combat cancer are illustrated.
Recent advances in understanding of fundamental immunology have created new insights into the dynamic interactions between tumors and the immune system. This includes new understanding of T- and B-cell interaction, immune inhibitory mechanisms including the biology of T regulatory cells, myeloid suppressor cells, and dendritic cell subsets. Enhanced understanding of mechanisms underlying T-cell anergy such as arginine deprivation, immunosuppressive cytokines, defective innate and interferon response pathways, and NKG2D downregulation have all provided new insight into suppression of anti-tumor immunity and tumor evasion. In addition to emerging understanding of tumor evasion, new immune targets such as CTLA4 blockade, NK stimulatory receptors, manipulation of the antigen processing and presentation, cytokine and costimulatory responses all provide new possibilities for enhancing anti-tumor immunity even in tumors previously felt to be resistant to immune attack. Several of these strategies have already been realized in the clinic. The volume will explore evolving paradigms in antigen presentation, dendritic cell biology, the innate response and immunosuppressive mechanisms, and emerging strategies for manipulation of the immune system for therapeutic benefit that have realized success in neuroblastoma, leukemia, melanoma, lung cancer, and allogeneic transplantation. Early successes as well as failures will be highlighted to provide a snapshot of the state of clinical immunotherapy with an eye to future possibilities such as combination therapies, adoptive T-cell transfer, and the retargeting of immune cells via T-cell receptor engineering.
The interplay between tumors and their immunologic microenvironment is complex, difficult to decipher, but its understanding is of seminal importance for the development of novel prognostic markers and therapeutic strategies. The present review discusses tumor-immune interactions in several human cancers that illustrate various aspects of this complexity and proposes an integrated scheme of the impact of local immune reactions on clinical outcome. Current active immunotherapy trials have shown durable tumor regressions in a fraction of patients. However, clinical efficacy of current vaccines is limited, possibly because tumors skew the immune system by means of myeloid-derived suppressor cells, inflammatory type 2 T cells and regulatory T cells (Tregs), all of which prevent the generation of effector cells. To improve the clinical efficacy of cancer vaccines in patients with metastatic disease, we need to design novel and improved strategies that can boost adaptive immunity to cancer, help overcome Tregs and allow the breakdown of the immunosuppressive tumor microenvironment.
The oral mucosa is a challenging environment from an immunological perspective, containing discrete niches with a unique architecture and function that requires precise adjustment of the immune system. Being the port of entry to the gastrointestinal and respiratory tracts, the oral cavity is also constantly challenged by antigens derived from air and food. Moreover, the oral cavity is the sole tissue of the body harboring a hard surface (i.e. the tooth) that is exposed to the hostile external environment, resulting in the formation of a complex biofilm that has local and systemic effects. To deal with such challenges, the oral immune system aims to prevent the invasion of pathogens/harmful antigens and to tolerate non-pathogenic counterparts in order to maintain homeostasis. In recent years, numerous studies have addressed these fundamental issues, revealing sophisticated mechanisms engaged by the immune system to maintain oral mucosal homeostasis and to combat various immunological insults. Some of these studies have identified novel immunological mechanisms, emphasizing the uniqueness of the oral immune system and the necessity to further investigate its functions.
This book highlights information derived primarily from clinical samples, with particular reference to theoretical and scientific aspects of the human immune system. This text will focus on topics that range from host-pathogen interactions in infectious disease to host immune response in cancer, allergic diseases, neuroinflammatory diseases, and autoimmune disorders. The reader will also have a well-rounded understanding of the behavior of the immune system with particular emphasis on the role of immunoproteomics in immunotherapy, neuroprotective immunity for neurodegenerative and neuroinfectious disease, leukemia-associated dendritic cell induction of adaptive immunity dysregulation, and the role of immune checkpoint inhibitors in cancer, infection, as well as neuroinflammation. Taken together, the contents of this book are intended for both clinicians and researchers in academia and industry.
Maintaining optimal immune function is at the cornerstone of disease prevention and management. The realization that lifestyle factors such as exercise, nutrition, sleep and stress can be targeted to optimize immune function for the prevention and treatment of illness and disease has intensified among physicians and health care providers. Exercise immunology as a discipline came to the fore in the early 1990’s through formation of the International Society of Exercise and Immunology (ISEI). Since then, several major advances have been made including the understanding that: (i) physical activity is associated with fewer incidences and symptoms of infection; (ii) every bout of exercise facilitates the ongoing exchange of immune cells between the blood and tissues to increase immune surveillance; (iii) regular exercise lowers chronic low-grade inflammation and improves vaccine responses in the elderly; (iv) contracting skeletal muscle acts as an immune regulatory organ; (v) physical activity can improve immune markers in aging and multiple disease states (e.g. cancer, HIV, diabetes); (vi) exercise expedites infection resolution and restricts host-pathogen entry and dissemination.

Immunology is the study of the body's protection from foreign macromolecules or invading organisms and the responses to them. These invaders include viruses, bacteria, protozoa or even larger parasites. In addition, immune responses are developed against our own proteins (and other molecules) in autoimmunity and against our own aberrant cells in tumour immunity. The first line of defense against foreign organisms are barrier tissues such as the skin that stop the entry of organism into our bodies. A second line of defense is the specific or adaptive immune system which may take days to respond to a primary invasion (that is infection by an organism that has not hitherto been seen). This new book brings together new research spanning the globe dealing with this extremely important subject.
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.
