RNAseq transcriptome analysis of Streptococcus pyogenes HKU16 and an isogenic gshT mutant. Manuscript title: Streptococcus pyogenes hijacks host glutathione for growth and innate immune evasion

Project description:The nasopharynx and the skin are the major oxygen-rich anatomical sites for colonization by the human pathogen Streptococcus pyogenes (group A Streptococcus, GAS). To establish infection, GAS must survive oxidative stress generated during aerobic metabolism and the release of reactive oxygen species (ROS) by host innate immune cells. Glutathione is the major host antioxidant molecule while GAS is glutathione-auxotrophic. Here we report the molecular characterization of the ABC transporter substrate binding protein GshT in the GAS glutathione salvage pathway. We demonstrate that glutathione uptake is critical for aerobic growth of GAS and that impaired import of glutathione induces oxidative stress that triggers enhanced production of the reducing equivalent NADPH. Our results highlight the interrelationship between glutathione assimilation, carbohydrate metabolism, virulence factor production and innate immune evasion. Together, these findings suggest an adaptive strategy employed by extracellular bacterial pathogens to exploit host glutathione stores for their own benefit.

Comparison of gene expression changes in Streptococcus pyogenes in the presence of zinc

Project description:Manuscript title: Zinc disrupts central carbon metabolism and capsule biosynthesis in Streptococcus pyogenes. Macrophages and neutrophils release free zinc to eliminate phagocytosed bacterial pathogens. The study investigates the effect of how zinc toxicity affects Streptococcus pyogenes. Therefore, a microarray analysis was performed in S. pyogenes cells to determine gene expression changes when exposed to high levels of zinc. We discovered that a pathway involved in tagatose-6-phosphate metabolism was upregulated when the cells are under zinc stress.

Expression analysis of Streptococcus pyogenes MGAS315 induced with XIP pheromone

Project description:Whole genome expression profile comparing MGAS315 treated with XIP pheromone versus vehicle-treated cells Interpretations are described further in the manuscript to be submitted: authors Mashburn-Warren, Morrison, and Federle. Title: The Cryptic Competence Pathway in Streptococcus pyogenes is Controlled by a Peptide Pheromone. A two chip study using total RNA recovered from three separate cultures of Streptococcus pyogenes MGAS315, each treated with either XIP pheromone or with vehicle; RNA preparation of cultures receiving same type of treatment were pooled using equivalent amounts of RNA from each culture. RNA pools were fluorescently labeled and hybridized to arrays designed to the S. pyogenes NZ131 genome.
