This book was released on 2014-12-04 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissection of the specificity of host immune responses following infection with Mycobacterium tuberculosis is essential for designing effective vaccination and diagnostic biomarkers as well as for better understanding of immunopathogenesis of active tuberculosis. The articles in this volume of the Topics in Microbial Immunology review the significance of this area of research from both experimental models and clinical surveys. This includes T cell recognition of MHC permissive epitopes, use of algorithms for genome-based prediction of immunodominant epitopes, evaluation of candidate antigens/epitopes and adjuvants for vaccination and immunodiagnosis. Future research strategies indicate the need for better understanding of the relationship between epitope specificity and the phenotype of responding T cells and search for biomarkers with a capacity to discriminate and predict the change from latent infection to active disease. These research avenues have important potentials for improving the prevention and control of tuberculosis.

Download or read book Immunologic Mechanisms and Predictors of Susceptibility to Mycobacterium Tuberculosis written by Gillian Lee Beamer and published by . This book was released on 2009 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In contrast to low IFN-[gamma] and low CCL5, elevated levels of IL-10 in the lungs predicted reactivation TB approximately 4-8 weeks prior to disease onset in M.tb susceptible mice. Furthermore, IL-10 was shown to be a single cause of reactivation TB, as disease progression was delayed and protective immunity was enhanced by IL-10 blockade in vivo. Overall, these results indicate that single immune mediators may be used as biomarkers of TB disease progression in humans, and furthermore, that appropriately timed immunotherapeutic intervention may prevent the transition from controlled M.tb infection to active TB disease.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Identifying biomarkers for tuberculosis (TB) is an ongoing challenge in developing immunological correlates of infection outcome and protection. Biomarker discovery is also necessary for aiding design and testing of new treatments and vaccines. To effectively predict biomarkers for infection progression in any disease, including TB, large amounts of experimental data are required to reach statistical power and make accurate predictions. We took a two-pronged approach using both experimental and computational modeling to address this problem. We first collected 200 blood samples over a 2-year period from 28 non-human primates (NHP) infected with a low dose of Mycobacterium tuberculosis. We identified T cells and the cytokines that they were producing (single and multiple) from each sample along with monkey status and infection progression data. Machine learning techniques were used to interrogate the experimental NHP datasets without identifying any potential TB biomarker. In parallel, we used our extensive novel NHP datasets to build and calibrate a multi-organ computational model that combines what is occurring at the site of infection (e.g., lung) at a single granuloma scale with blood level readouts that can be tracked in monkeys and humans. We then generated a large in silico repository of in silico granulomas coupled to lymph node and blood dynamics and developed an in silico tool to scale granuloma level results to a full host scale to identify what best predicts Mycobacterium tuberculosis (Mtb) infection outcomes. The analysis of in silico blood measures identifies Mtb-specific frequencies of effector T cell phenotypes at various time points post infection as promising indicators of infection outcome. As a result, we emphasize that pairing wetlab and computational approaches holds great promise to accelerate TB biomarker discovery.
Download or read book Tuberculosis and the Tubercle Bacillus written by William R. Jacobs, Jr. and published by John Wiley & Sons. This book was released on 2017-09-01 with total page 1379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can today's innovative practices and molecular tools tame this ancient disease? One third of the world's population is infected with tuberculosis (TB), with about 10 million new cases annually. To combat TB and its agent, Mycobacterium tuberculosis, the World Health Organization launched The End TB Strategy, which aims to slash the suffering and cost of TB by 2035. This makes the second edition of Tuberculosis and the Tubercle Bacillus, edited by Jacobs, McShane, Mizrahi, and Orme, an extremely valuable resource for scientists and clinicians. The editors have gathered their colleagues from around the world to present the latest on the molecular biology of M. tuberculosis and related species, the host-pathogen interactions that enable invasion, and the host's immune response to M. tuberculosis infection. The basic, clinical, and translational research presented in this book supports the goals of WHO's End TB Strategy by driving toward the development of effective vaccines, rapid molecular diagnostics, and anti-TB drugs. Creating an effective tuberculosis vaccine. Understand the innate and adaptive immune response to M. tuberculosis infection, its study in established animal models, and how this information is being used to develop new vaccines against TB. Formulating new antituberculosis drugs. Learn the challenges and methods for evaluating new drugs in preclinical trials with a focus on drugs that work against "persisters" and those that act on the electron transport complex and ATP synthase of M. tuberculosis. Overcoming the challenges of diagnosing tuberculosis. Review new diagnostic tools that are simple, rapid, affordable, specific, sensitive, and safe, including molecular-based diagnostic methods such as GeneXpert MTB/RIF. Using molecular, genomic, and bioinformatics tools to understand the biology and evolution of Mycobacterium. Explore current research on the molecular mechanisms that M. tuberculosis uses to evade the immune system, enter a state of nonreplicating persistence, and become reactivated. The second edition of Tuberculosis and the Tubercle Bacillus presents the latest research on a microorganism that is exquisitely well adapted to its human host. This pathogen continues to confound scientists, clinicians, and public health specialists, who will all find much valuable information in this comprehensive set of reviews.

This book was released on 2015-01-15 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: Latent tuberculosis infection (LTBI), defined as a state of persistent immune response to prior-acquired Mycobacterium tuberculosis antigens without evidence of clinically manifested active TB, affects about one-third of the world's population. Approximately 10% of people with LTBI will develop active TB disease in their lifetime, with the majority developing it within the first five years after initial infection. Currently available treatments have an efficacy ranging from 60% to 90%. Systematic testing and treatment of LTBI in at-risk populations is a critical component of WHO's eight-point framework adapted from the End TB Strategy to target pre-elimination and, ultimately, elimination in low incidence countries. OVERVIEW: Recognizing the importance of expanding the response to LTBI, in 2014 WHO developed Guidelines on the Management of Latent Tuberculosis Infection. The guidelines are primarily targeted at high-income or upper middle-income countries with an estimated TB incidence rate of less than 100 per 100 000 population, because they are most likely to benefit from it due to their current TB epidemiology and resource availability. The overall objective of the guidelines is to provide public health approach guidance on evidence-based practices for testing, treating and managing LTBI in individuals with the highest risk of progression to active disease. Specific objectives include identifying and prioritizing at-risk population groups for targeted intervention of LTBI testing and treatment, including defining an algorithm, and recommending specific treatment options. The guidelines are expected to provide the basis and rationale for the development of national guidelines for LTBI management based on available resources, epidemiology of TB including intensity of transmission, the health-care delivery system of the country, and other national and local determinants.

Download or read book Antibody Fc written by Margaret Ackerman and published by Academic Press. This book was released on 2013-08-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibody Fc is the first single text to synthesize the literature on the mechanisms underlying the dramatic variability of antibodies to influence the immune response. The book demonstrates the importance of the Fc domain, including protective mechanisms, effector cell types, genetic data, and variability in Fc domain function. This volume is a critical single-source reference for researchers in vaccine discovery, immunologists, microbiologists, oncologists and protein engineers as well as graduate students in immunology and vaccinology. Antibodies represent the correlate of protection for numerous vaccines and are the most rapidly growing class of drugs, with applications ranging from cancer and infectious disease to autoimmunity. Researchers have long understood the variable domain of antibodies, which are responsible for antigen recognition, and can provide protection by blocking the function of their target antigen. However, recent developments in our understanding of the protection mediated by antibodies have highlighted the critical nature of the antibody constant, or Fc domain, in the biological activity of antibodies. The Fc domain allows antibodies to link the adaptive and innate immune systems, providing specificity to a wide range of innate effector cells. In addition, they provide a feedback loop to regulate the character of the immune response via interactions with B cells and antigen-presenting cells. Clarifies the different mechanisms of IgG activity at the level of the different model systems used, including human genetic, mouse, and in vitro Covers the role of antibodies in cancer, infectious disease, and autoimmunity and in the setting of monoclonal antibody therapy as well as naturally raised antibodies Color illustrations enhance explanations of the immune system
