Natural killer (NK) cells are innate lymphoid cells that have a significant role in regulating the defenses against cancer development and certain viral infections. They are equipped with an array of activating and inhibitory receptors that stimulate or diminish NK cell activity, respectively. Inhibitory receptors include, among others, the MHC class I ligands killer cell immunoglobulin-like receptors (KIR) in humans, and members of the Ly49 family of receptors in mice, and CD94/NKG2A. Activating receptors include cytokine and chemokine receptors, and those that interact with ligands expressed on target cells, such as the natural cytotoxicity receptors or NCRs (NKp30, NKp44 and NKp46), NKG2D, CD244 and DNAM-1. In addition, NK cells express Fc?RIIIA or CD16, the receptor that exerts antibody-dependent cell mediated cytotoxicity (ADCC). NK cells also express the death ligands FasL and TRAIL. The killing or sparing of target cells depends on the integration of distinct signals that originate from NK cell receptors. NK cells spare healthy cells that express normal levels of MHC class I molecules and low amounts of stress-induced self-molecules, whereas they kill target cells that down-regulate MHC class I molecules and/or up-regulate stress-induced self-molecules. The latter are common signatures of virus-infected cells and tumors. All the accumulated knowledge on NK cell biology, along with many clinical observations, is driving multiple efforts to improve the arsenal of NK cell-based therapeutic tools in the fight against malignant diseases. Indeed, NK cell-based immunotherapy is becoming a promising approach for the treatment of many cancers. It is well known that NK cells have a significant role in the anti-tumor effect of therapeutic antibodies that use ADCC as a mechanism of action. In addition to this, administration of autologous and allogeneic NK cells after activation and expansion ex vivo is used in the treatment of cancer. Moreover, adoptive transfer of NK cell lines has been tested in humans, and genetically modified NK cells expressing chimeric antigen receptors are being studied in preclinical models for potential use in the clinic.

Natural killer (NK) cells have been at the forefront of immunology for two decades. During that time, a great amount of information about these cells has been obtained. They are important in antiinfectious and antitumoral defense and shape the adaptive immune response. In addition, they can act as immunoregulatory cells. In recent years, the therapeutic potential of NK cells in cancer immunotherapy has become increasingly evident. This book describes in detail current knowledge about NK cells and covers a broad range of NK cell-related topics, including those that are not frequently reviewed, e.g. NK cells and allergy or NK cells and skin diseases.

NK Cells in Cancer Immunotherapy

Pages : 329 pages

Natural killer (NK) cells are crucial components of the innate immune system and play critical roles in host immunity against viral infections and cancer. NK cells' activity is controlled by the interaction of a wide range of receptors expressed on their surfaces with cell surface ligands. Opposite signals delivered by inhibitory and activating receptors tightly regulate NK cells' cytotoxicity. Natural killer cells can discriminate between normal and cancer cells. NK cells are known to directly recognize and kill malignant cells or induce apoptosis. However, tumor cells have the ability to evade those attacks. The main mechanisms involve the lack of expression or downregulation of the expression of major histocompatibility complex (MHC) class I molecules and secretion of soluble NKG2D ligands by tumor cells. Furthermore, tumors harbor a population of cancer stem cells (CSCs), which can drive tumor progression and therapeutical resistance. This chapter highlights the roles of NK cells in tumor immunosurveillance and their applications for cancer immunotherapy. NK cell biology and function as well as the role of their receptor interactions will be described. We will discuss the therapeutic applications of NK cells in cancer and NK cells targeting CSCs as a promising strategy for cancer therapy.

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.
