Killer Cell Dynamics

This book reviews how mathematical and computational approaches can be useful to help us understand how killer T-cell responses work to fight viral infections. It also demonstrates, in a writing style that exemplifies the point, that such mathematical and computational approaches are most valuable when coupled with experimental work through interdisciplinary collaborations. Designed to be useful to immunoligists and viroligists without extensive computational background, the book covers a broad variety of topics, including both basic immunological questions and the application of these insights to the understanding and treatment of pathogenic human diseases.

As the research has continued, it has become increasingly clear that natural killer (NK) cells are critical sentinels of the innate immune response, playing important roles in protecting the body from numerous pathogens and cancer in addition to contributing to normal pregnancy and impacting the outcomes of transplantation. While the first edition provided a valuable collection of classical cellular and in vivo techniques to study NK cell functions, the Second Edition of "Natural Killer Cell Protocols: Cellular and Molecular Methods" brings together more recently developed methods, more refined techniques, and detailed protocols designed to study NK cells within specialized tissue sites in both mice and humans. In this collection of methods, international leaders in the field cover topics ranging from the analysis of the various stages of NK cell development and maturation to specialized techniques for the identification of ligands for NK cell receptors. This volume also includes an appendix, providing a rich resource summarizing available reagents to study NK cells, cross-referencing KIR nomenclature, and detailing the many HLA ligands for various KIR family members. As a volume in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and thorough notes sections, highlighting tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, "Natural Killer Cell Protocols: Cellular and Molecular Methods, Second Edition" seeks to aid researchers and further advance our understanding of the functions, maturation, and regulation of these fascinating and dynamic cells.

This volume contains collection of Natural Killer Cell methodologies relevant for both basic and translational research. These methodologies present new developments in the natural killer (NK) cell field, such as understanding the influence of NK cells metabolism on its function, identifying complexity of NK cell subsets through mass cytometry, and determining the emergence of memory NK cells in murine model of MCMV infection. Methods that study NK cell migration and cytotoxicity through endpoint analysis or live single cell imaging are also discussed. Chapters also describe methods pertaining to translational application of NK cells, such as ex vivo expansion of NK cells on K562 cell lines genetically modified to express either membrane bound IL-15 or membrane bound IL-21, large scale NK cell culture, current techniques for engineering NK cells to express chimeric antigen receptors or chemokine receptors using retroviral vectors, electroporation of mRNA, and the natural phenomenon of trogocytosis. Written in the highly successful Methods in Molecular Biology series format, these chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Cutting edge and thorough, Natural Killer Cells: Methods and Protocols is a valuable resource for researchers who not only want to understand mechanisms that govern NK cell behavior and diversity, but also for those who want to understand how to systematically evaluate NK cells for adoptive immunotherapy applications.

Natural Killer Cells explains the importance of killer cells and how they are produced. It mentions that the most likely explanation for killer cell production is that they serve as a complementary system for T cells as a primary defense against viruses. However, these cells defend against certain viruses only, such as herpes viruses and influenza viruses. The book also explains the primary functions of killer cells, and it discusses how these cells help recognize damaged tissues, limit further damage to tissues, and regenerate damaged tissues. It discusses how these cells mature and develop, and it covers the different isolation, culture, and propagation methods of these cells. Furthermore, it focuses on the different killer cells that are present in various parts of the human body. The book concludes by explaining that natural killer cells are utilized for clinical therapy of malignancies, and that they have led to positive outcomes in the field of biology and medicine. Provides a broad, detailed coverage of the biology and interactions of NK cells for students, fellows, scientists, and practitioners Includes figures, histologic sections, and illustrations of the ontogeny of NK cells

Mathematical Modeling and Immunology An enormous amount of human effort and economic resources has been directed in this century to the fight against cancer. The purpose, of course, has been to find strategies to overcome this hard, challenging and seemingly endless struggle. We can readily imagine that even greater efforts will be required in the next century. The hope is that ultimately humanity will be successful; success will have been achieved when it is possible to activate and control the immune system in its competition against neoplastic cells. Dealing with the above-mentioned problem requires the fullest pos sible cooperation among scientists working in different fields: biology, im munology, medicine, physics and, we believe, mathematics. Certainly, bi ologists and immunologists will make the greatest contribution to the re search. However, it is now increasingly recognized that mathematics and computer science may well able to make major contributions to such prob lems. We cannot expect mathematicians alone to solve fundamental prob lems in immunology and (in particular) cancer research, but valuable sup port, however modest, can be provided by mathematicians to the research aspirations of biologists and immunologists working in this field.

Currently, more than 36 million people are infected with HIV. Although the introduction of highly active anti-retroviral therapy (HAART) has led to substantial advances in the clinical management of HIV infected individuals, HAART cannot completely eliminate the virus. This is because CD4 T helper cells, harboring the virus, remain dormant reservoirs. These reservoirs are difficult to measure and are present even in HAART-treated HIV infected individuals with undetectable levels of HIV in the blood. A growing body of studies has revealed follicular helper (Tfh) CD4 T cells, a highly differentiated CD4 T cell population localized in immunologically sanctuary sites (follicle/germinal center), as a major reservoir of HIV. The present Frontiers in Immunology eBook compiles 16 timely review articles focusing on the dynamics of major follicular immune cell types in HIV/SIV infection and their potential role for disease pathogenesis and the viral persistence in the lymph node. This eBook provides a comprehensive presentation of recent published work on lymph node and especially Tfh cell dynamics in HIV infection and we hope that it will be useful for our further understanding of how such dynamics affect the interplay between virus and host as well as for the discovery of novel therapeutic targets in the fight against HIV.

Bringing new contributions to science might be challenging, however, this is our path to evolution. We cannot assume that we know everything, but it is only our curiosity that can lead us to answers. Therefore, we can and we should keep trying, seeking new and different paths. There is always a starting point: asking yourself „Why?”, and the answer will follow… The purpose of the present book is the study of some mathematical models of cell dynamics and convex optimization problems applied to chronic myeloid leukemia, a type of leukemia also known as chronic myelogenous leukemia. We take into consideration basic concepts, methods and results from the theory of differential equations, such as: existence, uniqueness, monotonicity, boundedness, continuous dependence on data and stability of solutions.
