Gene expression profile in peritoneal macrophage infected with Listeria monocytogenes

Project description:Several Toll-like receptors are activated by Listeria monocytogenes infection, resulting in the activation of MyD88 dependent signaling pathway. However, the negative role of MyD88 in gene expresson is unclear. To address this, we performed microarray analysis of mRNAs from WT or MyD88-/- peritoneal macrophages infected with Listeria monocytogenes.

Transcriptome Sequencing of mice eosinophils upon Listeria monocytogenes (L.m.) infection

Project description:Mature eosinophils were differentiated from mouse bone marrow progenitors We performed transcriptome sequencing on Listeria monocytogenes infected eosinophils and resting eosinophils to shed light on the transcriptional changes of cytokines and chemokines.

The response of splenic macrophages from C57BL/6 and Ch25h-/- mice to infection with Listeria monocytogenes.

Project description:WT (C57BL/6) and Ch25h-/- mice were infected i.v. with 1e5 CFU of Listeria monocytogenes. At day 3 post-infection, ~100,000 resident splenic macrophages (CD11b+, Ly6G-, Ly6clow) were isolated by flow cytometery and analyzed by RNA-seq

Listeria monocytogenes transcriptional response to bile

Project description:These studies were designed to examine the acute Listeria monocytogenes transcriptional response to mammalian (porcine) bile. Triplicate WT Listeria monocytogenes (strain 10403S) were grown to mid-log in BHI at 37 Â°C. Samples were divided, and either treated or not treated by addition of porcine bile (Sigma, to 1% final) for 30 minutes.

CtsR Regulon in Listeria monocytogenes

Project description:The foodborne pathogen Listeria monocytogenes uses a number of transcriptional regulators, including the negative regulator CtsR, to control gene expression under different environmental conditions and in response to stress. Gene expression patterns of DctsR log phase cells were compared to both wt and ictsR-mcsA log phase cells grown with 0.5mM IPTG to identify CtsR-dependent genes.We identified 62 CtsR-dependent genes that showed significant expression ratios (adj. P < 0.05), with ≥ 1.5-fold differential expression either between ΔctsR and wt or between ΔctsR and ictsR-mcsA. Keywords: Listeria monocytogenes, CtsR regulon, log phase

HrcA Regulon in Listeria monocytogenes

Project description:The foodborne pathogen Listeria monocytogenes uses a number of transcriptional regulators, including the negative regulator HrcA, to control gene expression under different environmental conditions and in response to stress. Gene expression patterns of DhrcA stationary phase cells were compared to wt to identify hrcA-dependent genes. We identified 61 HrcA-dependent genes that showed significant expression ratios (adj. P < 0.05), with ≥ 1.5-fold differential expression between ΔhrcA and wt. Combined with microarray analysis, Hidden Markov Model searches show HrcA directly repress at least 8 genes. Keywords: Listeria monocytogenes, HrcA regulon, stationary phase

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.

Listeria monocytogenes exposure to chlorine dioxide

Project description:Listeria monocytogenes strain 10403S has been studied extensively for stress response activity toward multiple stressors (acid, osmotic, cold, high temperature, etc.) as well as multiple stress regulons (SigB, CtsR, HrcA, etc.). Here we aimed to determine the transcriptional response of Listeria monocytogenes in early log phase towards the strong oxidative stress imposed by ClO2. The elucidation of such a response allows for further a more completel understanding of the mechanism of inactivation by sanitizers, specifically ClO2.

Immunopeptidomics-based design of highly effective mRNA vaccine formulations against Listeria monocytogenes

Project description:Listeria monocytogenes is a foodborne intracellular bacterial pathogen leading to human listeriosis. Despite a high mortality rate and increasing antibiotic resistance no clinically approved vaccine against Listeria is available. To identify antigens for this bacterial pathogen that can be encoded in mRNA vaccine formulations, we screened for Listeria epitopes presented on the surface of infected human cell lines by mass spectrometry-based immunopeptidomics. In between more than 15,000 human self-peptides, we detected 68 Listeria epitopes from 42 different bacterial proteins, including several known antigens. Peptide epitopes presented on different cell lines were often derived from the same bacterial surface proteins, classifying these antigens as potential vaccine candidates. Encoding these highly presented antigens in lipid nanoparticle mRNA vaccine formulations resulted in high levels of protection in vaccination challenge experiments in mice. Our results pave the way for the development of a clinical mRNA vaccine against Listeria and demonstrate the power of immunopeptidomics for next-generation bacterial vaccine development.
