Title Dual RNA-seq – Comparative Dual RNA-seq in pig macrophages
Organisms Sus scrofa; Salmonella enterica subsp. enterica serovar Typhimurium str. SL1344
Experiment type Expression profiling by high throughput sequencing
Summary Bacteria possess many small noncoding RNAs whose regulatory roles in pathogenesis are little understood due to a paucity of macroscopic phenotypes in standard virulence assays. Here, we use a novel Dual RNA-seq approach for a single-step simultaneous RNA profiling in both pathogen and host to reveal molecular phenotypes of sRNAs during infection with Salmonella Typhimurium. We identify a new PhoP/Q-activated small RNA which upon bacterial internalization acts to temporally control the expression of both, invasion-associated effectors and virulence genes required for intracellular survival. This riboregulatory activity is shown to adjust the human response to replicating Salmonella, and have a pervasive impact on host RNA expression both inside and outside protein-coding regions including infection-specific alterations of an array of long noncoding RNAs. Our study provides a paradigm for a comprehensive RNA-based analysis of intracellular bacterial pathogens without their physical purification from a host and a new discovery route for hidden functions of pathogen genes.
