Pathogenic bacteria of the genus Bartonella can induce vasoproliferative lesions during infection. The underlying mechanisms are unclear, but involve secretion of an unidentified mitogenic factor. Here, we use functional transposon-mutant screening in Bartonella henselae to identify such factor as a pro-angiogenic autotransporter, called BafA. The passenger domain of BafA induces cell proliferation, tube formation and sprouting of microvessels, and drives angiogenesis in mice. BafA interacts wit ...[more]

Dual RNA-sequencing of nontypeable Haemophilus influenzae and host cell transcriptomes reveals new aspects of host-pathogen interface

Project description:Characterization of host-pathogen interactions is critical for the development of next-generation therapies and vaccines. Classical approaches involve the use of transformed cell lines and/or animal models which may not reflect the complexity and response of the human host. We reconstituted the ciliated human bronchial epithelium in vitro using primary bronchial epithelial cells to simultaneously monitor the infection-linked global changes in nontypeable Haemophilus influenzae (NTHi) and infected host epithelia gene expression by dual RNA-seq. Acquisition of a total of nearly 2,5 billion sequences allowed construction of high-resolution strand-specific transcriptome maps of NTHi during infection of host mucosal surface and monitoring of metabolic as well as stress-induced host-adaptation strategies of this pathogen. As a part of our screening, we identified a global profile of noncoding transcripts that are candidate small RNAs regulated during human host infection in Haemophilus species. Temporal analysis of host mRNA signatures revealed significant dysregulation of target cell cytoskeleton elicited by bacterial infection, with a profound effect on intermediate filament network of bronchial epithelium. Our data provide a robust and comprehensive catalogue of regulatory responses that drive NTHi pathogenesis and gives novel insights into complex crosstalk between the host and the invading pathogen. Primary human bronchial epithelium was infected with NTHi at a multiplicity of 100:1. Total RNA was isolated at 1, 6, 24 and 72 h post-infection in three biologically-independent experiments and cDNA libraries were prepared and sequenced with Illumina HiSeq 2500 sequencer. At each time point, between 60 and 180 million total reads per sample were obtained of which approximately one-third could be aligned to non-rRNA regions of the bacterial and human genomes

Host metabolic reprogramming during immune activation promotes intracellular bacterial survival (host and bacteria)

Project description:Intracellular pathogens, such as Salmonella enterica serovar Typhimurium (S.Tm), are able to sense and respond to a changing host cell environment. Macrophages exposed to microbial products undergo metabolic changes that are increasingly understood to drive a productive inflammatory response. However, the role of macrophage metabolic reprogramming in bacterial adaptation to the intracellular environment has not been explored. Here we show that changes in host metabolic state serve as a signal detected byS.Tm. Using metabolic profiling and dual RNA-seq, we show that succinate accumulates in infected macrophages and is sensed by intracellular S.Tm to promote induction of virulence genes. Succinate uptake by the bacterium drives induction of pmrAB-dependent genes and SPI-2 virulence-associated regulon. S.Tm lacking the DcuB transporter for succinate uptake display impaired intracellular survival. Our work demonstrates that accumulation of metabolic intermediates, necessary for macrophage activation, promote intracellular survival of pathogens, opening a new realm of metabolic host-pathogen crosstalk.

Paired single-cell host profiling with multiplex-tagged bacterial mutants reveals intracellular virulence-immune networks VI

Project description:Encounters between host cells and intracellular bacterial pathogens lead to complex phenotypes that determine the outcome of infection. Single-cell RNA-sequencing (scRNA-seq) are increasingly used to study the host factors underlying diverse cellular phenotypes. But current approaches do not permit the simultaneous unbiased study of both host and bacterial factors during infection. Here, we developed scPAIR-seq, an approach to analyze both host and pathogen factors during infection by combining multiplex-tagged mutant bacterial library with scRNA-seq to identify mutant-specific changes in host transcriptomes. We applied scPAIR-seq to macrophages infected with a library of Salmonella Typhimurium secretion system effector mutants. We developed a pipeline to independently analyze redundancy between effectors and mutant-specific unique fingerprints, and mapped the global virulence network of each individual effector by its impact on host immune pathways. ScPAIR-seq is a powerful tool to untangle bacterial virulence strategies and their complex interplay with host defense strategies that drive infection outcome.
