This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycobacterium tuberculosis associated granuloma formation can be viewed as a structural immune response that can contain and halt the spread of the pathogen. In several mammalian hosts, including non-human primates, Mtb granulomas are often hypoxic, although this has not been observed in wild type murine infection models. While a presumed consequence, the structural contribution of the granuloma to oxygen limitation and the concomitant impact on Mtb metabolic viability and persistence remains to be fully explored. We develop a multiscale computational model to test to what extent in vivo Mtb granulomas become hypoxic, and investigate the effects of hypoxia on host immune response efficacy and mycobacterial persistence. Our study integrates a physiological model of oxygen dynamics in the extracellular space of alveolar tissue, an agent-based model of cellular immune response, and a systems biology-based model of Mtb metabolic dynamics. Our theoretical studies suggest that the dynamics of granuloma organization mediates oxygen availability and illustrates the immunological contribution of this structural host response to infection outcome. Furthermore, our integrated model demonstrates the link between structural immune response and mechanistic drivers influencing Mtbs adaptation to its changing microenvironment and the qualitative infection outcome scenarios of clearance, containment, dissemination, and a newly observed theoretical outcome of transient containment. We observed hypoxic regions in the containment granuloma similar in size to granulomas found in mammalian in vivo models of Mtb infection. In the case of the containment outcome, our model uniquely demonstrates that immune response mediated hypoxic conditions help foster the shift down of bacteria through two stages of adaptation similar to thein vitro non-replicating persistence (NRP) observed in the Wayne model of Mtb dormancy. Finally, the adaptation in part contributes to the ability of Mtb to remain dormant for years after initial infection.

Download or read book Understanding the Host Immune Response Against Mycobacterium tuberculosis Infection written by Vishwanath Venketaraman and published by Springer. This book was released on 2018-09-26 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: According to the World Health Organization, approximately one third of the world’s population is latently infected with Mycobacterium tuberculosis (M. tb [LTBI]), of whom about 9 million have active tuberculosis (TB). It is estimated that approximately 2 million individuals die each year from active TB. An estimated 14.4% of these individuals have HIV and M. tb co-infection. TB has long been known to be one of the leading causes of death in HIV-infected individuals. Recent evidence now indicates that individuals with type 2 diabetes, the elderly, and chronic smokers are also increasingly susceptible to TB infection, the ability of their immune system to fight off active TB infection having been compromised by their condition. This book therefore aims to provide a detailed review of recent advances in the research that involves characterizing the host’s immune responses against TB infection in conditions such as HIV, diabetes, chronic cigarette smoking and aging, and strategies to restore favorable immune responses against this deadly pathogen.
