Book Description
This book adds to a intensively investigated question of immunological research. How do regulatory T cells mediate their function to ensure tolerance against self-antigen? The author analyzes the interaction via the cytokine interleukin 2 between T helper cells, which mediate immune responses, and regulatory T cells. Since both cell types depend on interleukin 2 to mediate their functions, competition for interleukin 2 is likely. A mathematical model is developed to describe the interaction. This model focuses on the interleukin 2 receptor dynamics on helper and regulatory T cells and the extracellular interleukin 2 diffusion. The interleukin 2 receptor dynamics is governed mainly by an autocrine positive feedback loop on both cell types. However, its differential regulation results in a switch-like up-regulation of the receptors on T helper cells and a gradual adaptation of the receptor levels to extracellular interleukin 2 supply on regulatory T cells. This difference enables regulatory T cells to efficiently compete for interleukin 2 and deprive T helper cells of their growth factor. Cell culture experiments verify these findings. It can be shown that the antigen stimulus and the intercellular distance are relevant control parameters for competition. Other mechanisms are described for suppression of T helper cell action by regulatory T cells; competition for interleukin 2 may act in concert with them.

Book Description
This book offers a detailed review of the remarkable advances that have been made in research on the pathogenesis of a number of neuroimmunological diseases, as well as outlining novel treatments including the use of monoclonal antibodies. Written by renowned experts who have made major contributions in the field, such as identifying neuromyelitis optica as an immunopathological clinical condition, identifying the role of ganglioside and ganglioside-complex antibodies in Guillain-Barré syndrome, and developing a novel treatment for POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) syndrome, the book summarizes recent advances in basic and clinical research. Neuroimmunological Diseases is a useful resource for not only researchers but also neurologists who are engaged in the management of neuroimmunological diseases.

Book Description
This book provides readers an extensive overview of recent progress in basic and clinical research on cancer immunotherapy. Thanks to rapid advances in molecular biology and immunology, it has become increasingly evident that cancer growth is influenced by host immune responses. With the success of a number of clinical trials, immunotherapy has become a promising treatment modality of cancer. This book covers five major topics, including monoclonal antibodies, biological response modifiers, cancer vaccines, adoptive cellular therapy and oncolytic viruses. It also examines the combination of different immune strategies as well as the combination of immunotherapy with other treatments to increase anti-tumor effects. Through the comprehensive discussion of the topic, the book sheds valuable new light on the treatment of tumors.

Book Description
Whole new areas of immunological research are emerging from the analysis of experimental data, going beyond statistics and parameter estimation into what an applied mathematician would recognise as modelling of dynamical systems. Stochastic methods are increasingly important, because stochastic models are closer to the Brownian reality of the cellular and sub-cellular world.

Book Description
T cells play a vital role mediating adaptive immunity, a specific acquired resistance to an infectious agent produced by the introduction of an antigen. There are a variety of T cell types with different functions. They are called T cells, because they are derived from the thymus gland. This volume discusses how T cells are regulated through the operation of signaling mechanisms. Topics covered include positive and negative selection, early events in T cell receptor engagement, and various T cell subsets.

Book Description
This book provides researchers the opportunity to investigate type-2-associated diseases in their laboratories. Beginning with chapters describing various models of type-2 immunity, the volume then continues by detailing cellular protocols designed to identify, characterize, and assess the function of key adaptive and innate immune cells involved in type-2 inflammation; approaches to isolate and evaluate specific cellular subsets at the genetic, epigenetic, and molecular level; protocols to assess type-2 immunity and its relationship to organismal and metabolic systems (ex. Microbiome). This book concludes with a section that explores the use of primary human cells in evaluating relevance to the clinic. Written in the highly successful Methods in Molecular Biology series format, 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. Vital and authoritative, Type 2 Immunity: Methods and Protocols aims to provide a broad network of methods that can be used to develop a hypothesis and investigate its potential from bench to beside.

Book Description
The sirtuin family of proteins (SIRT1-7) received a lot of attention in recent years as they serve as metabolic sensors that control not only metabolism, but also aging and lifespan regulation. As such, sirtuins are strong targets for the treatment of age-related metabolic diseases, including obesity, diabetes, and cancer. Indeed, many research groups as well as pharmaceutical companies discovered food components and/or drugs that target the sirtuins and provide significant health benefits. This book focuses on various aspects of sirtuin biology, from basic biochemistry, via molecular function, to its role in (fighting) human disease.
