Over the last several years the field of humanized mice has matured and developed into an essential component of translational research for HIV/AIDS. Humanized mice serve both as vehicles for discovery and as highly sophisticated platforms for biomedical research. In addition, humanized mice have demonstrated outstanding potential for the investigation of critical aspects of the infection and pathogenesis of the hepatitis and herpes viruses, as well as highly relevant microbial infections such as tuberculosis and malaria. Humanized Mice for HIV Research provides a comprehensive presentation of the history, evolution, applications, and current state of the art of this unique animal model. An expansion of twelve review articles that were published in Humanized Mice by Springer in 2008 (Eds: Nomura T, Watanabe T, Habu S), this book expertly captures the outstanding progress that has been made in the development, improvement, implementation, and validation of humanized mouse models. The first two parts of this book cover the basics of human-to-mouse xenotransplantation biology, and provide critical information about human immune cell development and function based on individual models created from different immunodeficient strains of mice. The third and fourth parts investigate HIV-1 biology, including different routes of transmission, prevention, treatment, pathogenesis, and the development of adaptive immunity in humanized mice. The fifth part shows the broad applicability of humanized mice for therapeutic development, from long-acting antiretroviral combinations to genetic manipulations with human cells and cell-based approaches. The sixth part includes liver tissue engineering and the expansion of humanized mice for many other human cell-tropic pathogens.

The world has recorded losses in terms of human life as well as extensive time spent in experimentation with development of new drugs, elucidation of disease mechanism(s), and therapeutic agent discovery. Ethical and legal issues cojoin in slowing down scientific discoveries in medicine and biology. The past two (2) decades, therefore, have seen tremendous attempts that largely are successful in developing animal models with the characteristics of mimicking, approximating, or expressing transplanted human organs/tissues. These models or rather approaches seem to be fast, cost-effective, and easy to maintain compared to primates. This book is a collection of expert essays on animal models of human diseases of global interest. A visible objective of the book is to provide real-time experimental approach to scientists, clinicians, ethicists, medicolegal/medical jurisprudence workers, immunologists, postgraduate students, and vaccinologists and informative and multidisciplinary approach for the identification of new therapeutic targets and biomarkers using animal models as well as investigating the pathogenesis and therapeutic strategies of human diseases. An increased understanding of the genetic, molecular, and cellular mechanisms responsible for the development of human diseases has laid out the foundation for the development of rational therapies mainly with animal models.

The term humanized mouse in this text refers to a mouse in which human tissues and cells have been transplanted and show the same biological function as they do in the human body. That is, the physiological properties and functions of tra- planted human tissues and cells can be analyzed in the mouse instead of using a living human body. It should therefore be possible to study the pathophysiology and treatment of human diseases in mice with good reproducibility. Thus, the hum- ized mouse can be used as a potent tool in both basic and clinical research in the future. The development of appropriate immunodeficient mice has been indispensable in the creation of the humanized mouse, which has been achieved through many years of efforts by several laboratories. The first stage on the road to the humanized mouse was the report on nude mice by Isaacson and Cattanach in 1962. Thereafter, nude mice were studied in detail by Falanagan and, in 1968, Pantelouris found that these mice have no thymus gland, which suggested that the mice lack transplan- tion immunity against xenografts such as human hematopoietic stem cells. At the Nude Mouse Workshops (organized by Regard, Povlsen, Nomura and colleagues) that were held nine times between 1972 and 1997, the possibility of creating a humanized mouse using nude mice was extensively examined. The results, however, showed that certain human cancers can be engrafted in nude mice, but unfortunately engraftment of normal human tissue was almost impossible.

A successful vaccine for the prevention and/or immunotherapy against HIV/AIDS is one of the prominent challenges of the 21st century. To date, all human vaccine trials against this virus/disease have resulted in failure, or at best have shown very low efficacy. The scientific community dealing with HIV/AIDS has unanimously proposed a focus on basic science, with the intention of identifying correlates of protection that can serve as guides in developing and evaluating vaccine preparation. However, Nature seems to have already found several ways of dealing with infections by HIV and related primate lentiviruses, either by resisting infection or, once infected, avoiding immune damage and immunodeficiency. Models of Protection Against HIV/SIV will allow for an in-depth reflection on the perspectives for vaccine and therapy research derived from important recent studies. It will be authored by some of the most well known specialists in the field of HIV resistance/protection: including F. Barré-Sinoussi (2008 Nobel Prize for Medicine winner), B. Walker, S. Rowland-Jones, A. Telenti, M. Lederman and F. Plummer. This book is structured in a unique way, looking at three models of resistance/protection separately and then comparing the models against one another to provide its readership with a detailed examination of the research that is most predominant in the search for a vaccine. This structure presents the information in an easy-to-understand format and gives the book a cross-discipline appeal -- an important reference for those in the scientific community, medical care, public health and academia alike.
