Quantitative proteomics revealed modulation of macrophages by MetQ gene of Streptococcus suis serotype 2.

ABSTRACT: MetQ gene of Streptococcus suis serotype 2 deletion strain has attenuated antiphagocytosis. However,the mechanism of antiphagocytosis and pathogenesis of MetQ in SS2 has remained unclear. In this study, stable isotope labeling by amino acids in cell culture (SILAC) based liquid chromatography-mass spectrometry (LC-MS) and subsequent bioinformatics analysis was used to determine differentially expressed proteins of RAW264.7 cells infected with △MetQ and ZY05719, aimed at elucidating the mechanism of antiphagocytosis and innate immunity of macrophages infected by Streptococcus suis.

Streptococcus suis serotype 2 (SS2) is a serious zoonotic pathogen; it can lead to symptoms of streptococcal toxic shock syndrome (STSS) in humans and sepsis in pigs, and poses a great threat to public health. The SS2 MetQ gene deletion strain has attenuated antiphagocytosis, although the mechanism of antiphagocytosis and pathogenesis of MetQ in SS2 has remained unclear. In this study, stable isotope labeling by amino acids in cell culture (SILAC) based liquid chromatography-mass spectrometry (L ...[more]

Understanding Streptococcus suis serotype 2 infection in pigs through a transcriptional approach

Project description:Streptococcus suis serotype 2 is an important pathogen of pigs, and the disease it causes is characterized by meningitis, septicaemia and pneumonia with high mortality. The pathogen is also an emerging zoonotic agent and threatens humans that are exposed to pigs or their by-products. We investigated the response of PBMC (Peripheral Blood Mononuclear Cell), brain and lung tissues to infection with S. suis 2 strain SC19 by using the Affymetrix Porcine Genome Array. Six piglets free of S. suis 2 were allocated randomly to the infected group and the uninfected group. Each piglet of the infected group was intravenous injection with Streptococcus suis 2 strain SC19 at a dose of 3Ã105 colony-forming units (CFU). Each piglet of the noninfected group was treated similarly with an identical volume of PBS as control. At 24 h after challenge, the pigs were slaughtered and their brains, lungs and PBMC were collected with RNase-free equipment for microarray analysis.

Gene expression analysis of human monocytic cells (THP-1) exposure to Streptococcus suis serotype 2

Project description:Streptococcus suis is an important zoonosis pathogen that causes significant economic losses worldwide characterized by meningitis, septicaemia, arthritis, bronchopneumonia endocarditis. Streptcoccus suis 2 strain SC19 was isolated in Sichuan province in China, during the outbreak in 2005. Septicemia is most popular symptoms for SC19 infection, and mortality is high. We used human acute monocytic leukemia cell line (THP-1) infected SC19 to analysis the pathomechanism of septicemia in SS2 infection. Human acute monocytic leukemia cell line (THP-1) cells were stimulated with Streptcoccus suis 2 (SS2) strain SC19. We added SS2 to THP-1 cells at a MOI of 1:1 (bacteria/cells). Uninfected control cells were incubated with PBS only. After 3 hours incubation, cells were collected for RNA extraction and hybridization on Affymetrix microarrays. A total of 4 samples were challenged, and 4 samples were used as controls. 4 microarrays were used in this experiment.

Investigating the effect of CodY mutation on the gene expression in Streptococcus suis serotype 2 SC19 strain.

Project description:To investigate the effect of CodY mutation on the gene expression in Streptococcus suis serotype 2 SC19 strain, we have employed whole genome microarray expression profiling as a discovery platform to identify genes regulated by CodY mutation. DNA microarray analysis was performed using an Agilent custom-designed oligonucleotide microarray. Based upon the whole genome sequence of SC19 , specific 60-mer oligonucleotide probes were designed using eArray (https://earray.chem.agilent.com/earray/), to cover all annotated genes. Probes were printed seven times on microarray slides. Three biological replicates of total RNA from two wild type strains and from two codY mutant strains were amplified and labeled with Cy3-CTP using Low Input Quick Amp Labeling Kit, one-color(Agilent technologies, US), following the manufacturer’s instructions. Labeled cRNA was purified using the RNeasy mini kit (Qiagen). After fragmentation, microarray slides were hybridized with 600 ng Cy3-labeled cRNA. Hybridization was performed at 65 °C for 17 h with rotation at 10 rpm. Microarray slides were washed and scanned by an Agilent Microarray Scanner (G2565BA). Those genes with greater than two-fold change ratios were regarded as differentially expressed genes. codY mutation induced gene expression in Streptococcus suis serotype 2 SC19 was detected in two wild type and two codY mutated strain of Streptococcus suis serotype 2.

Microarray analysis of the Streptococcus suis serotype 2 transcriptional response to acidic conditions

Project description:For a pathogen such as Streptococcus suis serotype 2, ecological success is determined by its ability to sense the environment and mount an appropriate adaptive transcriptional response. Thus, determining conditions for analysis of gene expression in vitro that are representative of the in vivo environment is critical for understanding the contributions of transcriptional response pathways to pathogenesis. In this study, we used analysis of the global expression profile in response to acidic pH in vitro and identified a set of regulated genes involved in diverse cellular processes. 196 (11%) genes were differentially regulated by the acid stress: 92 (47%) were down-regulated at low acid (pH 5.8) relative to the neutral condition (pH 7.2), whereas 104 (53%) were up-regulated at pH 5.8 versus pH 7.2. To confirm the microarray data, 16 genes were measured by quantitative RT-PCR. There was a strong positive correlation (r = 0.96) between the results obtained by microarray and quantitative RT-PCR. The data showed that S. suis S2 is equally capable of inducing an acid tolerance response with maximal protection provided after adaptation at pH 5.8 for survival. A cDNA microarray imprinted with 2156 genes representing about 98% of the Streptococcus suis serotype 2 genome was used for transcriptome analysis. For two-sample (reference vs. test) microarray hybridization, four independent bacterial cultures from each condition (pH 5.8, pH 7.2) were prepared as biological replicates for RNA isolation. Accordingly, four dual-fluorescence-labeled cDNA probes were prepared to hybridize with four slides. Pairwise comparisons were made using dye-swaps to avoid labeling bias. A ratio of mRNA levels (test/reference) was calculated for each gene. Significant changes of gene expression were identified with the SAM software. After the SAM analysis, only genes with at least 2-fold changes in expression were collected for further analysis.

investigation of the pathogenesis of H1N1 influenza virus and swine streptococcus suis serotype 2 co-infection in pigs by microarray analysis

Project description:Swine H1N1 influenza virus and streptococcus suis serotype 2 (SS2) are two important contributors to the porcine respiratory disease complex, which have significant economic impacts. Clinically, swine influenza virus and swine streptococcus suis co-infection is common, which will increase the mortality. However, the pathogenesis of the co-infection remains largely unkown. To explore it, gene expression profiling was to performed to detect comprehensive analysis of the global host response induced by H1N1 virus infection alone, SS2 infection alone, H1N1-SS2 co-infection and PBS control.
