Tuberculosis remains one of the world’s biggest killers responsible for more than a million deaths each year. New drugs and new vaccines are urgently needed to tackle the disease. This book describes the application of this century’s first new science, systems biology, to the study of tuberculosis. After introducing the basic principles of systems biology, successive chapters describe how systems-based approaches provide new insights into gene regulation, metabolism, protein-protein interaction, host-pathogen interactions, the immune response, persistence, drug treatment and diagnosis of tuberculosis. This book will be an invaluable aid to anyone interested in exploring how the latest science is helping us to understand this ancient disease.
