Upon antigen encounter, naïve T cells differentiate into (i) effectors that combat infected or malignant cells, and at later time points, into (ii) memory cells that provide long-lasting immunity. This differentiation process allows some T cells to leave the confines of secondary lymphoid organs and to enter peripheral tissues in search of pathogens or tumor cells. These different environments pose specific challenges for effector and memory T cells to maintain homeostasis. T cells directed into the lungs are likely to encounter higher levels of oxygen, but lower amounts of nutrients than those directed into the intestinal epithelium. In addition to oxygen tension and nutrient concentrations, other key factors, such as the commensal flora and stromal components, create unique conditions that require tissue-specific adaptations of T cells. These steady state conditions can dramatically change during infection when inflammatory mediators and T cell growth factors are released, requiring the immediate response of T cells. The gradual changes imposed by growing tumors can also be challenging for T cells due to competition with rapidly cycling tumor cells that deplete essential resources of oxygen and glucose. The strategies that T cells employ to respond to the diverse cues from their surroundings are the focus of current research. It appears that next to circulating memory T cells that are confined to the circulation and those that survey all of the peripheral tissues, dedicated populations of resident memory T cells exist that can optimally adapt to the local circumstances within each tissue. Restrictions on the metabolic requirements of T cells residing in tumor tissue have been found to directly impact on effector functions such as cytokine production. The fundamental principles of how the machinery of T cells can translate local cues into tissue-specific differentiation processes are fascinating and warrant further investigation.

Human Gut Microbiota in Health and Disease: From Pathogenesis to Therapy is a comprehensive discussion of all the aspects associated with gut microbiota early colonization, its development and maintenance, and its symbiotic relationship with the host to promote health. Chapters illustrate the complex mechanisms and metabolic signalling pathways related to how the gut microbiota maintain proper regulation of glucose, lipid and energy homeostasis and immune response, while mediating inflammatory processes involved in the etiology of many chronic disease conditions. Details are provided on the primary etiological factors of chronic disease, the effects of gut dysbiosis and its associated disease conditions, while providing an overview of therapeutic strategies involving dietary fiber and prebiotics, fecal microbiota transplantation therapy and probiotics. Throughout the chapters, a comprehensive review of peer-reviewed animal and human studies is provided as evidence related to the history of human exposure, safety, tolerance, toxicity, nomenclature, and clinical efficacy of utilizing prebiotic fructans, s, as well as probiotic intervention, and dietary modification in the prevention and intervention of chronic disease conditions. With common use today of pharmaceutical medicine in treating symptoms, and frequent overuse of antibiotics in chronic disease within mainstream medical practice, understanding the etiological mechanisms of dysbiosis-induced chronic disease, and natural approaches that offer prevention and potential cures for these diseases is of vital importance to overall human health. - Details the complex relationship between human microbiota in the gut, oral cavity, urogenital tract and skin as well as their colonization, development and impact of factors that influence the relationship - Illustrates the mechanisms associated with dysbiosis-associated inflammation and its role in the onset and progression in chronic disease - Provides the primary mechanisms and comprehensive scientific evidence for the use of dietary modification, and pro- and pre-biotics in preventing and intervening in chronic disease

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.

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.

Methods in Toxicology, Volume 2: Mitochondrial Dysfunction provides a source of methods, techniques, and experimental approaches for studying the role of abnormal mitochondrial function in cell injury. The book discusses the methods for the preparation and basic functional assessment of mitochondria from liver, kidney, muscle, and brain; the methods for assessing mitochondrial dysfunction in vivo and in intact organs; and the structural aspects of mitochondrial dysfunction are addressed. The text also describes chemical detoxification and metabolism as well as specific metabolic reactions that are especially important targets or indicators of damage. The methods for measurement of alterations in fatty acid and phospholipid metabolism and for the analysis and manipulation of oxidative injury and antioxidant systems are also considered. The book further tackles additional methods on mitochondrial energetics and transport processes; approaches for assessing impaired function of mitochondria; and genetic and developmental aspects of mitochondrial disease and toxicology. The text also looks into mitochondrial DNA synthesis, covalent binding to mitochondrial DNA, DNA repair, and mitochondrial dysfunction in the context of developing individuals and cellular differentiation. Microbiologists, toxicologists, biochemists, and molecular pharmacologists will find the book invaluable.

The recent emphasis in biomedical research on translational biology and personalized medicine is revolutionizing conceptual and experimental approaches to understanding and improving human health. Translational Biology in Medicine begins with an introduction to experimental model systems for disease, such as cell lines, primary cells, stem cells and animal models for disease, followed by a systematic description of genetic and genomic profiling and biomarker validation currently used in biomedical research. Examples of translation studies that have used these models and methods are presented, including studies in aging, tissue repair and chronic infection, each with an emphasis on how personalized medicine is transforming biomedicine. Bioethical considerations in translational study design and bioethical considerations in biomedical research are then covered, before concluding remarks, and a look towards the future of personalized medicine. - Describes cellular and animal model systems used in translational research - Discusses the use of blood, genetic and genomic biomarkers for disease - Presents translational studies in aging, tissue repair and infectious disease biomedicine
