Cell Activation and Apoptosis in HIV Infection


Book Description

In the past decade, the global efforts in the control of HIV disease were basically concentrated on the search for anti-retroviral agents. So far, anti-HIV therapies have been shown to be disappointing because of rapid development of drug-resistant mutant variants. Despite this drawback in the therapeutic fight against HIV infection, antiviral research should be actively pursued. However, failure of antiviral therapy indicates that other avenues of research should be rapidly explored with the same energy. In this setting, striking advances have been recently made in the dissection and understanding of the viro-immunological processes governing the progressive destruction of lymphoid organs associated with AIDS develop ment, and HIV-induced activation and apoptosis have been identified as key phenomena of the immune system destruction. This book assembles the most recent advances on basic and clinical aspects ofT-cell activationiapoptosis in HIV infection and their implications for immunotherapy. These data were presented at an international symposium held on July 11-12, 1994, in Paris. The book is partitioned into 21 chapters covering four comprehensive fields: 1) T-celllmacrophage activation and HIV infection; 2) Apoptosis and viropathogenesis of HI V disease; 3) Apop tosis and immunopathogenesis ofHIV disease; 4) Mediators ofT-cell activationiapoptosis and therapeutic applications. We hope that this book will assist the readers in understanding recent advances in the viro-immunopathogenesis of HI V disease as well as the rationales for potential immune cell-targeted therapeutic interventions.

HLA-DR Antigens


Book Description




Human Cytomegalovirus


Book Description

This volume has gathered some of the experts in the field to review aspects of our understanding of CMV and to offer perspectives of the current problems associated with CMV. The editors and authors hope that the chapters will lead to a better understanding of the virus that will assist in the development of new and unique antivirals, a protective vaccine, and a full understanding of CMV's involvement in human disease.




Immunopathogenesis of HIV Infection


Book Description

During the last 5 years, major advances have been made in our understanding of the pathogenesis of human immunodeficiency virus (HIV) disease and in the development of new potent antiviral agents. With regard to HIV pathogenesis, several recent observations have not only changed our perspectives of HIV disease, but have been critical for the design of therapeutic strategies.







Nutrition and HIV


Book Description

The world continues to lose more than a million lives each year to the HIV epidemic, and nearly two million individuals were infected with HIV in 2017 alone. The new Sustainable Development Goals, adopted by countries of the United Nations in September 2015, include a commitment to end the AIDS epidemic by 2030. Considerable emphasis on prevention of new infections and treatment of those living with HIV will be needed to make this goal achievable. With nearly 37 million people now living with HIV, it is a communicable disease that behaves like a noncommunicable disease. Nutritional management is integral to comprehensive HIV care and treatment. Improved nutritional status and weight gain can increase recovery and strength of individuals living with HIV/AIDS, improve dietary diversity and caloric intake, and improve quality of life. This book highlights evidence-based research linking nutrition and HIV and identifies research gaps to inform the development of guidelines and policies for the United Nations’ Sustainable Development Goals. A comprehensive approach that includes nutritional interventions is likely to maximize the benefit of antiretroviral therapy in preventing HIV disease progression and other adverse outcomes in HIV-infected men and women. Modification of nutritional status has been shown to enhance the quality of life of those suffering HIV/AIDS, both physically in terms of improved body mass index and immunological markers, and psychologically, by improving symptoms of depression. While the primary focus for those infected should remain on antiretroviral treatment and increasing its availability and coverage, improvement of nutritional status plays a complementary role in the management of HIV infection.




HIV-1 Latency


Book Description

This volume summarizes recent advances in understanding the mechanisms of HIV-1 latency, in characterizing residual viral reservoirs, and in developing targeted interventions to reduce HIV-1 persistence during antiretroviral therapy. Specific chapters address the molecular mechanisms that govern and regulate HIV-1 transcription and latency; assays and technical approaches to quantify viral reservoirs in humans and animal models; the complex interchange between viral reservoirs and the host immune system; computational strategies to model viral reservoir dynamics; and the development of therapeutic approaches that target viral reservoir cells. With contributions from an interdisciplinary group of investigators that cover a broad spectrum of subjects, from molecular virology to proof-of-principle clinical trials, this book is a valuable resource for basic scientists, translational investigators, infectious-disease physicians, individuals living with HIV/AIDS and the general public.




Endothelial Dysfunction


Book Description

The endothelium enables communication between blood and tissues and is actively involved in cardiovascular homeostasis. Endothelial dysfunction has been recognized as an early step in the development of cardiovascular diseases: respectively, endothelium represents a potential therapeutic niche with multiple targets. The purpose of the book is to point out some recent findings of endothelial physiology and pathophysiology emphasizing various aspects of endothelial dysfunction connected to the body's internal and external environment. While basic features of the endothelium are presented in an introductory chapter, the authors of the following 17 chapters have provided extensive insight into some selected topics of endothelial (dys)function. The book would hopefully be useful for anyone interested in recapitulating endothelial (patho)physiology and expanding knowledge of molecular mechanisms involved in endothelial dysfunction, relevant also for further clinical investigations.




AIDS Pathogenesis


Book Description

Infection with the human immunodeficiency virus is characterized by the destruction of the host immune system as also reflected by a progressive loss of CD4-positive T-cells. This finally results in the host's incapacity to deal with opportunistic infections and the immune surveillance of tumors, a clinical status known as the Acquired Immunodeficiency Syndrome (AIDS). The book AIDS Pathogenesis provides the reader with a complete overview of the clinical course of HIV-1 infection. It describes the clinical aspects of primary infection, the different clinical outcomes of HIV-1 infection, and strategies for anti-viral treatment. In addition, more fundamental aspects of HIV-1 infection are reviewed. These include the biology of the virus and the novel insights in AIDS pathogenesis. Not only is the significance of an HIV-specific cellular and humoral immune response discussed, but also the possible incapacity of the adult human host to deal with T-cell destruction. Finally, the book discusses the currently used laboratory markers that allow for monitoring of the clinical course of infection.
