    Metabolism of intracellular Salmonella enterica: One lifestyle in intra-cellular infections

    The intracellular lifestyle of Salmonella enterica relies on the adaptation to nutritional conditions within the Salmonella-containing vacuole (SCV) in host cells. Based on previous results, metabolic requirements for Salmonella in the SCV shall be characterized further. This includes (i) prediction of intracellular phenotypes of mutant strains based on metabolic modeling and experimental tests, (ii) isotopologue profiling using 13C compounds in intracellular Salmonella, and (iii) complementation of metabolic defects for attenuated mutant strains. The collaborative work between the Dandekar and Hensel groups proposed for the second funding period should lead to a comprehensive understanding of the metabolic requirements of the intracellular lifestyle of Salmonella. Further analyses of intracellular phenotypes will be based on improved metabolic predictions. Vice versa, based on analyses of mutant phenotypes and isotopologue analyses, iterative refinement of metabolic flux models will be achieved. Our vision is a comprehensive understanding of the adaptation of Salmonella to its lifestyle in a membrane-bound compartment in mammalian cells. Towards an integrated model and profiting from SPP1316, we will do comparisons of the Salmonella lifestyle with other pathogens and their metabolic requirements during infection such as cytoplasmic lifestyle found in Listeria or within a membrane compartment as for Legionella.
