This book was released on 2017 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gut microbiome has a profound effect on human health and disease. The burgeoning body of research investigating the gut microbiome has illustrated its important roles on not only the local inflammatory diseases, such as inflammatory bowel disease, but also on systemic immunological disorders, such as autoimmune diseases. Many of these associations were determined at the level of metagenome analysis. This provides categorical information on both taxonomic composition and predicted functional capacities of the microbial community. This thesis tackles the problem of how gut microbiota affect human diseases using both these categories of assessment. Although the accumulating evidence suggested the important roles of gut microbiota in the human immune system and Crohn's disease (CD), the molecular mechanisms of how microbiome directly modulates immune responses and leads to CD progression remain unclear. To advance the current understanding of microbial roles in CD, we developed a systems biology approach to assess the human immune function in response to disease-associated microbial products. Progress in computational omics analysis of the microbiome in CD enables the functional inference and prediction of microbial metabolites. Both genetic and clinical studies suggested the involvement of human CD4+ T cells in CD progression. We therefore tabulated a set of microbial metabolites predicted to be differentially abundant in CD, and screened these microbial metabolites for their bioactivity in human CD4+ T cell functions. Our screen revealed 15 bioactive microbial metabolites, 3 previously reported and 12 unprecedented, with selective action on CD4+ T cell cytokine production. Mechanistic assessment of one novel microbe-derived metabolite, ascorbate, revealed apoptosis of activated human CD4+ T cells associated with selective inhibition of glycolytic energy metabolism. These findings suggest a substantial rate (11%) of bioactive metabolites among the predicted CD-associated metabolite reservoirs and provide evidence for novel modes of microbial activity targeting T cell metabolism. Emerging studies have characterized the association of taxonomic composition with systemic autoimmune diseases with various clinical phenotypes and modes of pathologic immune responses. In this thesis, we assessed systemic sclerosis (SSc), a previously unstudied autoimmune disease with respect to the microbiome, notable for both systemic manifestations and gastrointestinal involvement. The metagenomic study of mucosal-luminal interface (MLI) samples revealed a unique microbial composition associated with disease state. Patients with SSc had decreased abundances of Faecalibacterium and Clostridium, and increased abundances of Bifidobacterium, Lactobacillus, Fusobacterium and -Proteobacteria compared with healthy controls. In addition, the increase of Fusobacterium species and the decrease of Bacteroides fragilis were associated with moderate/severe gastrointestinal symptoms. We conducted an independent study of faecal samples from two independent cohorts of patients, from United States and Norway, that revealed a similar group of microbial taxa associations, and a greater dysbiosis in patients from the United States. These studies enable the specific targets for intervention to avert or treat the gastrointestinal involvement in systemic sclerosis. The study of gut microbiota is beginning to evolve from association toward causality. The functions of gut microbiota are not only restricted to local inflammatory responses but expanded to systemic immune regulations.i We hypothesized that gut microbiome may regulate host immune cellular responses by producing metabolites. We investigated the bioactive microbial factors regulating Crohn's disease, and explored the potential microbial taxonomic biomarkers in a systemic autoimmune disorder, SSc. Those improved understandings of the microbiome activity and metabolism may inform therapeutic strategies and ultimately improve patient health.

Download or read book Physiological and Clinical Aspects of Short Chain Fatty Acids written by John H. Cummings and published by Cambridge University Press. This book was released on 2004-12-02 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive volume to look at the importance of short-chain fatty acids in digestion, the function of the large intestine and their role in human health. Short-chain fatty acids are the major product of bacterial fermentation of dietary carbohydrates in the human and animal large intestine. They represent the major end products of digestive processes occurring in the caecum and large intestine. As such, they form an important dietary component and it is increasingly recognised that they may have a significant role in protecting against large bowel cancer and in metabolism. Prepared by an international team of contributors who are at the forefront of this area of research, this volume will be an essential source of reference for gastroenterologists, nutritionists and others active in this area.

This book was released on 2019-11-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Increasing evidence suggests that microbiota and especially the gut microbiota (the microbes inhabiting the gut including bacteria, archaea, viruses, and fungi) plays a key role in human physiology and pathology. Recent findings indicate how dysbiosis—an imbalance in the composition and organization of microbial populations—could severely impact the development of different medical conditions (from metabolic to mood disorders), providing new insights into the comprehension of diverse diseases, such as IBD, obesity, asthma, autism, stroke, diabetes, and cancer. Given that microbial cells in the gut outnumber host cells, microbiota influences human physiology both functionally and structurally. Microbial metabolites bridge various—even distant—areas of the organism by way of the immune and hormone system. For instance, it is now clear that the mutual interaction between the gastrointestinal tract and the brain (gut–brain axis), often involves gut microbiota, indicating that the crosstalk between the organism and its microbial residents represents a fundamental aspect of both the establishment and maintenance of healthy conditions. Moreover, it is crucial to recognize that beyond the intestinal tract, microbiota populates other host organs and tissues (e.g., skin and oral mucosa). We have edited this eBook with the aim of publishing manuscripts focusing on the impact of microbiota in the development of different diseases and their associated treatments.]

Download or read book Intestinal Microbiota in Health and Disease written by Eduardo J. Schiffrin and published by CRC Press. This book was released on 2014-02-11 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now considered an organ with defensive and metabolic capabilities, the intestinal microbiota plays a major role in the local host immune system development and education. It contributes to the generation of a homeostatic balance characterized by the capacity to react against pathogens while remaining hyperresponsive/tolerant against commensals. This homeostatic response depends on bacteria and bacterial product sensing by innate immune cells and their molecular asset at the intestinal mucosa. This book captures the enormous progress that has been accomplished in this field in recent years.
Download or read book Immunoregulation written by Nicola Fabris and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunoregulation is one of the areas which has witnessed the most explosive advances of immunology during the past decade. It is in this area that the current view of the immune system has arisen and developed. There is indeed little doubt that immune reactions are primarily determined by messages which are genera ted within the immune system and passed among different types of immunologie cells. This cell communication not only determines the type, intensity and duration of the response after perturbation of the immune system by exogenous antigens, but it is also essential for preventing autoimmune reactions and their clinical conse quences. In order to assure aperfect balance within the enormous com plexity of the immune system, it is not surprising that multiple self-regulatory mechanisms are organized at different levels, such as antibody feedback, idiotypic-anti-idiotypic responses, suppres sor and helper T cells, lymphokine signals and genetic require ments. A nu mb er of observations in recent years have, however, demonstrated that consistent contributions to the immunological homeostasis are given also by signals generated outside of the immune system, namely,in the central and autonomous nervous system as weIl as in the endocrine apparatus. Furthermore, the interactions between the immune system and the other body homestatic mechanisms seem to be bidirectional: if immunological cells may be targets of neuroendocrinological factors, immunological products seem in turn to contribute to the neuro endocrine homeostasis.
Download or read book Molecular Mechanisms of Bacterial Infection via the Gut written by Chihiro Sasakawa and published by Springer. This book was released on 2009-10-09 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our gut is colonized by numerous bacteria throughout our life, and the gut epithelium is constantly exposed to foreign microbes and dietary antigens. Thus, the gut epithelium acts as a barrier against microbial invaders and is equipped with various innate defense systems. Resident commensal and foreign invading bacteria interact intimately with the gut epithelium and can impact host cellular and innate immune responses. From the perspective of many pathogenic bacteria, the gut epithelium serves as an infectious foothold and port of entry for disseminate into deeper tissues. In some instances when the intestinal defense activity and host immune system become compromised, even commensal and opportunistic pathogenic bacteria can cross the barrier and initiate local and systematic infectious diseases. Conversely, some highly pathogenic bacteria, such as those highlighted in this book, are able to colonize or invade the intestinal epithelium despite the gut barrier function is intact. Therefore, the relationship between the defensive activity of the intestinal epithelium against microbes and the pathogenesis of infective microbes becomes the basis for maintaining a healthy life. The authors offer an overview of the current topics related to major gastric and enteric pathogens, while highlighting their highly evolved host (human)-adapted infectious processes. Clearly, an in-depth study of bacterial infectious strategies, as well as the host cellular and immune responses, presented in each chapter of this book will provide further insight into the critical roles of the host innate and adaptive immune systems and their importance in determining the severity or completely preventing infectious diseases. Furthermore, under the continuous threat of emerging and re-emerging infectious diseases, the topic of gut-bacteria molecular interactions will provide various clues and ideas for the development of new therapeutic strategies.
