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.

The vertebrate immune system defends the organism against invading pathogens while at the same time being self-tolerant to the body’s own constituents thus preserving its integrity. Multiple mechanisms work in concert to ensure self-tolerance. Apart from purging the T cell repertoire from auto-reactive T cells via negative selection in the thymus dominant tolerance exerted by regulatory T cells plays a major role in tolerance imposition and maintenance. Among the various regulatory/suppressive cells hitherto described, CD4+CD25+ regulatory T cells (Treg) and interleukin-10 producing T regulatory 1 (Tr1) cells have been studied in most detail and are the subject of most articles in this issue. Treg, also called "natural" regulatory T cells, will be traced from their intra-thymic origin to the site of their action in peripheral lymphoid organs and tissues. The repertoire of Treg is clearly biased towards recognition of self-antigens, thereby potentially preventing autoimmune diseases such as gastritis and oophoritis. Regulatory T cells, however also control infections, allergies and tolerance to transplanted tissues and this requires their induction in the periphery under conditions which are not yet fully understood. The concept of dominant tolerance, by far not novel, will offer new insights and hopefully tools for the successful treatment of autoimmune diseases, improved cancer immunotherapy and transplant survival. The fulfillment of these high expectations will, however, require their unambiguous identification and a better understanding of their mode of action.

“Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.

This book highlights the important role free fatty acids (FFA) play as potential drug targets. While FFA have long been considered byproducts of cell metabolism, they are now recognized as ligands that regulate cell and tissue function via G-protein-coupled receptors. At least three receptors have been identified for which FFA appear to be the endogenous ligands.

Chromatin Signaling and Diseases covers the molecular mechanisms that regulate gene expression, which govern everything from embryonic development, growth, and human pathologies associated with aging, such as cancer. This book helps researchers learn about or keep up with the quickly expanding field of chromatin signaling. After reading this book, clinicians will be more capable of explaining the mechanisms of gene expression regulation to their patients to reassure them about new drug developments that target chromatin signaling mechanisms. For example, several epigenetic drugs that act on chromatin signaling factors are in clinical trials or even approved for usage in cancer treatments, Alzheimer's, and Huntington's diseases. Other epigenetic drugs are in development to regulate various class of chromatin signaling factors. To keep up with this changing landscape, clinicians and doctors will need to stay familiar with genetic advances that translate to clinical practice, such as chromatin signaling. Although sequencing of the human genome was completed over a decade ago and its structure investigated for nearly half a century, molecular mechanisms that regulate gene expression remain largely misunderstood. An emerging concept called chromatin signaling proposes that small protein domains recognize chemical modifications on the genome scaffolding histone proteins, facilitating the nucleation of enzymatic complexes at specific loci that then open up or shut down the access to genetic information, thereby regulating gene expression. The addition and removal of chemical modifications on histones, as well as the proteins that specifically recognize these, is reviewed in Chromatin Signaling and Diseases. Finally, the impact of gene expression defects associated with malfunctioning chromatin signaling is also explored. - Explains molecular mechanisms that regulate gene expression, which governs everything from embryonic development, growth, and human pathologies associated with aging - Educates clinicians and researchers about chromatin signaling, a molecular mechanism that is changing our understanding of human pathology - Explores the addition and removal of chemical modifications on histones, the proteins that specifically recognize these, and the impact of gene expression defects associated with malfunctioning chromatin signaling - Helps researchers learn about the quickly expanding field of chromatin signaling

Systems and Synthetic Immunology focuses on the similarities between biology and engineering at the systems level, which are important for applying engineering theories to biology problems. With the advent of new genomic techniques, there are numerous systematic investigations underway in the scientific world. This volume highlights techniques that can be used to effectively combine two of the most essential biological fields - Systems Biology and Synthetic Immunology. The respective chapters discuss the role of synthetic immunology in biotechnology, production of biomaterials, and their use in vaccine delivery. Further topics include the importance of cytokines; the use of genomic engineering tools in immunotherapy; immunosensors; nanotherapeutics; and bioinformatics tools in biomedical applications. Given its scope, the book offers readers an up-to-date and comprehensive review of this unique and dynamic field of research.
