Deciphering Mycobacterium tuberculosis sulfur metabolism during infection

Mycobacterium tuberculosis, the pathogen responsible for tuberculosis, is an intracellular bacterium that infects mainly macrophages and can persist for a long time in pulmonary lesions called granulomas. To survive and multiply inside macrophages, the bacteria have to acquire nutrients that will fuel their metabolism. While carbon and nitrogen metabolisms of bacterial pathogens have been studied for decades, sulfur metabolism is currently gaining interest. Sulfur is required to synthetize the two sulfur-containing amino acids cysteine and methionine but also to produce mycothiol (the main redox buffer in mycobacteria) and Fe-S clusters of enzymes. Sulfur acquisition is therefore essential for M. tuberculosis survival during infection and pathways of sulfur metabolism could be interesting targets for the development of new antimicrobial strategies. In this context, my PhD project aims at understanding M. tuberculosis sulfur metabolism during infection in vivo.
