4-hydroxy-2-nonenal (4-HNE) induced transcriptional changes in Listeria monocytogenes

ABSTRACT: Pathogens must counteract a wide array of antimicrobial responses, including the reactive oxygen species (ROS) burst. ROS mediated oxidation of host membrane poly-unsaturated fatty acids (PUFAs) leads to the production of the toxic alpha-beta carbonyl 4-hydroxy-2-nonenal (4-HNE). 4-HNE has been studied extensively in the context of sterile inflammation but understanding of its role during bacterial infection remains limited. In this work we found that 4-HNE is generated during bacterial infection and that the intracellular pathogen Listeria monocytogenes induces a specific set of genes in response to 4-HNE exposure.

ISG15 counteracts Listeria monocytogenes infection

Project description:ISG15 is primarily documented as an interferon-stimulated, ubiquitin-like protein (ubl), which has anti-viral activity. Although ISG15 was the founding member of the ubl protein family, very little is known about its function. We have found that ISG15 expression in non-phagocytic cells is dramatically induced upon Listeria infection and that surprisingly this induction can be Type I Interferon independent. Listeria-mediated ISG15 induction depends on the cytosolic surveillance pathway, which senses bacterial DNA and signals through STING, TBK1, IRF3 and IRF7. Most importantly, we observed that ISG15 expression restricts Listeria infection both in vitro and in vivo. We then made use of Stable Isotope Labeling in tissue culture (SILAC) to identify the ISGylated proteins that could be responsible for the ISG15-mediated protective effect. Our SILAC analysis revealed that overexpression of ISG15 leads to a striking ISGylation of integral membrane proteins of the endoplasmic reticulum and Golgi apparatus, which correlates with increased canonical secretion of cytokines. Taken together, our data reveal a previously uncharacterized signaling pathway that restricts Listeria infection and acts via ISGylation, reinforcing the view that ISG15 is a key component of the innate immune arsenal of the mammalian host.

Intracellular transcription by multiple Listeria monocytogenes strains

Project description:These studies were designed to examine the transcription of Listeria monocytogenes strains 10403S and LO28 during intracellular replication in mammalian macrophages. Duplicate WT Listeria monocytogenes (strains 10403S and LO28) were used to infect mouse bone marrow-derived macrophages (BMMs). Bacterial RNA was harvested at 4 hours post-infection.

Listeria monocytogenes Transcriptome with RNA-Seq

Project description:The stationary phase stress response transcriptome of the human bacterial pathogen Listeria monocytogenes was defined using RNA sequencing (RNA-Seq) with the Illumina Genome Analyzer. Specifically, bacterial transcriptomes were compared between stationary phase cells of L. monocytogenes 10403S and an otherwise isogenic DsigB mutant, which does not express the alternative sigma factor σB, a major regulator of genes contributing to stress response. Keywords: Transcriptome and differential expression analyses

Immunopeptidomics identification of Listeria monocytogenes T cell epitopes in mice

Project description:Listeria monocytogenes is a foodborne intracellular bacterial model pathogen. Protective immunity against Listeria depends on an effective CD8 T-cell responses, but very few T cell epitopes are known in mice as most common animal infection model for listeriosis. To identify epitopes we screened for Listeria epitopes presented in the spleen of infected mice by mass spectrometry-based immunopeptidomics. In between more than 6,000 mouse self-peptides presented on MHC Class I molecules, we detected 26 Listeria peptides from 25 different bacterial proteins, including previously reported antigens. Bacterial immunopeptides with confirmed fragmentation spectra were further tested for their potential to CD8 T cells, revealing VTYNYINI from the putative cell wall surface anchor family protein LMON_0576 as a novel bona fide peptide epitope. Despite its high biological potency in a prime boost model, this epitope did not protect against challenge infection but can be used as a research tool to probe CD8 T cell responses in mouse models of Listeria infection. Our results demonstrate the power of immunopeptidomics for bacterial antigen identification but highlight the need for in-depth immune characterization for vaccine candidate selection.

Infection with Listeria monocytogenes alters the placental transcriptome and eicosanome

Project description:Introduction: Placental infection and inflammation are risk factors for adverse pregnancy outcomes, including preterm labor. However, the mechanisms underlying these outcomes are poorly understood. Methods: To study this response, we have employed a pregnant mouse model of placental infection caused by the bacterial pathogen Listeria monocyogenes, which infects the human placenta. Through in vivo bioluminescence imaging, we confirm the presence of placental infection and quantify relative infection levels. Infected and control placentas were collected on embryonic day 18 for RNA sequencing to evaluate gene expression signatures associated with infection by Listeria. Results: We identified an enrichment of genes associated with eicosanoid biosynthesis, suggesting an increase in eicosanoid production in infected tissues. Because of the known importance of eicosanoids in inflammation and timing of labor, we quantified eicosanoid levels in infected and uninfected placentas using semi-targeted mass spectrometry. We found a significant increase in the concentrations of several key eicosanoids: leukotriene B4, lipoxin A4, prostaglandin A2, prostaglandin D2, and eicosatrienoic acid. Discussion: Our study provides a likely explanation for dysregulation of the timing of labor following placental infection. Further, our results suggest potential biomarkers of placental pathology and targets for clinical intervention.

Proteomics-based identification of ISG15 modification sites during Listeria monocytogenes infection

Project description:ISG15 is an interferon-stimulated, ubiquitin-like protein, with anti-viral and anti-bacterial activity, however its precise mechanism of action during viral or bacterial infection remains elusive. We previously found that ISG15 restricts Listeria infection both in vitro and in vivo and identified ISGylated proteins that could be responsible for the protective effect. Here, we endeavored to map the in vivo ISGylome following Listeria infection to mechanistically elucidate the function of ISG15 in host defense. To do so we combined a genetic approach employing a murine model of deregulated ISGylation with quantitative proteomics of immune-enriched endogenous ISG15 modification sites. In this way, we mapped 930 ISG15 sites in 438 proteins. In addition, we also quantified protein level changes in the host proteome following infection. Gene ontology analysis revealed that ISGylated proteins were mostly enriched in proteins which alter cellular metabolic processes, including four upstream modulators of the catabolic and antibacterial pathway of autophagy. Structural analysis further revealed that a number of ISG15 modifications can occur at catalytic sites or dimerization interfaces of enzymes. Finally, we showed that animals and cells with deregulated ISGylation have increased infection-induced autophagy through the modification of mTOR, WIPI2, and AMBRA1. Taken together, these findings ascribe a putative role of ISGylation to temporarily reprogram organismal metabolism following infection through direct modification of a variety of enzymes in the liver.

Transcription profiling of Listeria monocytogenes after infection into murine macrophages

Project description:P388D1 murine macrophages were cultured in 85 mm tissue culture plates to about semi confluency. L. monocytogenes serotypes (1/2a EGD-e, 4a L99, 4b CLIP80459 and 4b F2365) were infected to the P388D1 cell monolayer at a MOI of 100 per eukaryotic cell. Infection was carried for 45 min and followed by addition of fresh medium containing 20 M-5g/ml gentamicin. The medium of the plates (containing 20 M-5g/ml gentamicin) infected with L. monocytogenes serotypes were replaced after 2 h post infection with fresh medium containing 50 M-5g/ml gentamicin. At each step the plates were washed extensively with 1x PBS. Incubation of the bacterial tissue culture plates was carried out in a humidified incubator for up to 4 h post infection.
