Transcriptional response of bovine macrophages after infection with two Argentinean Mycobacterium bovis isolates

ABSTRACT: Infection of cattle with Mycobacterium bovis causes severe financial hardship in many countries, in addition to presenting a health risk for humans. As an intracellular pathogen, M. bovis, adapted to survive and thrive within the intramacrophage environment. However, little is known about expression patterns in the macrophage, particularly in the bovine host. In this study, DNA microarray analysis was used to detect genes expressed in Holstein bovine macrophages derived from peripheral blood mononuclear cells infected during four hours with two Argentinean strains of M. bovis, a virulent strain, 04-303 and an attenuated strain, 534. Genes encoding antrax toxin receptor, cell division and apoptosis regulator, ankyrin proteins that are found within the membrane associated cytoskeleton, protein of cell differentiation and regulators of endocytic traffic of membrane were more strongly expressed in infected macrophages.

Blood from healthy Holstein bovines was taken in sterile conditions and peripheral blood mononuclear cells (PBMC) were separated from heparinized blood. PBMCs were used to prepare ten independent cultures which were incubated at 37C for one week in RPMI 1640 complete medium supplemented with 10% of autologous plasma. Four cultures were infected with viable cells of M. bovis virulent strain 04-303, four with avirulent strain 534 and two were left as uninfected controls. Four hours post infection, the cells were scraped, lysed. RNA was extracted, labeled and hybridized to ten Affymetrix Bovine Genome arrays.

Comparative gene expression profiling analysis of RNA-seq data for bovine macrophages infected with two Myocbacterium bovis strains of variable virulence and co-cultured with autologous lymphocytes.

Project description:In this study we compared the transcriptome of bovine macrophages infected with two Mycobacterium bovis strains of variable virulence, co-cultured with autologous lymphocytes. We used the highly virulent M. bovis strain called Mb04-303 and the attenuated Mb534 strain. We first observed that only the infection of bovine macrophages with the virulent strain, Mb04-303, induced in peripheral bovine mononuclear cells a powerful innate immune response capable of controlling the intracellular mycobacterial replication.By RNAseq analysis we found that infections with Mb04-303 downregulated the KEAP1-NFE2L2 pathway that encodes a transcriptional factor involved in antioxidant genes and inflammasome activation and upregulated the type 1 interferon signalling pathway, compared to the infections with the attenuated Mb534 strain.

Early response of bovine alveolar macrophages to infection with live and heat-killed Mycobacterium bovis

Project description:Bovine tuberculosis, caused by Mycobacterium bovis, is a disease of considerable economic importance yet comparatively little is known about the bovine immune response to the disease. Alveolar macrophages are one of the first cells to encounter mycobacteria following infection. In this experiment we investigated the early transcriptional response of bovine alveolar macrophages following infection with M. bovis. The transcriptional response to heat-killed M. bovis was also investigated to look for genes that are only differentially transcribed in response to the live organism. Five-condition experiment, uninfected, live and heat-killed M. bovis-infected bovine alveolar macrophages from five cattle infected for two and four hours. Comparisons were within animal. Dye swaps were incorporated into the design.

Responses of Monocytes derived macrophages from TB-infected and TB-free cattles to in vitro M.bovis challenge

Project description:Macrophages from cattles with different infectious status of bovine tuberculosis have different responses to in vitro Mycobacterium bovis challenge. This is confirmed in our previous study exploring several immune-related genes using qPCR. Microarrays can help us better understand the differences by screening thousands of genes. Monocytes Derived Macrophages from 3 TB-infected cattles and 3 TB-free cattles were challenged with Mycobacterium bovis at a MOI of 10 at 6 hours, and the control group were the same unchallenged macrophages at 6 hours.

Transcriptional response of bovine moncocyte-derived macrophages to infection with strains of Mycobacterium bovis and Mycobacterium avium subspecies paratuberculosis

Project description:Mycobacterium bovis (M. bovis) and Mycobacterium avium subspecies paratuberculosis (MAP) are important pathogens of cattle, causing bovine tuberculosis and Johne’s disease respectively. M. bovis and MAP infect residential macrophages in the lung and intestines respectively and subvert the macrophage biology to create a survival niche. To investigate this interaction we simultaneously studied the transcriptional response of bovine monocyte-derived macrophages to infection with two strains of M. bovis (AF2122/97 and G18) and two strains of MAP (C & L1).

Genome-wide Analysis of mRNAs and lncRNAs in Mycoplasma Bovis infected and non-infected bovine mammray gland tissues.

Project description:Mycoplasma bovis (M. bovis) causes to the diseases such as arthritis, pneumonia, abortion and mastitis causing to great losses in dairy bovine industries. It undertakes significant functions in the regulation of the immune response formed by many RNA type bacteria such as Messenger RNA (mRNAs) and Long noncoding RNA (lncRNAs). mRNA and lncRNA expression profiles still cannot be majorly known in the bovine mammary gland tissues infected with M. bovis. To illuminate this issue, transcription analysis has been conducted regarding mRNA and IncRNAs in the breast tissues belonging to Holstein cattle infected and not infected with M. Bovis. Differently expressed 1310 mRNAs and 57 IncRNAs have been determined in the bovine mammary gland tissues infected and not infected with M. Bovis. In addition; 392 novel lncRNAs have been detected. Also; it has been found that 19 novel lncRNAs are expressed in a different way. It has been revealed in gene ontology analysis that the differently expressed mRNAs and IncRNAs play a significant role in many vital biological pathways such as Metabolic pathways, T cell receptor signaling pathway, TGF-beta signaling pathway, Pathways in cancer, PI3K-Akt signaling pathway, NF-kappa B signaling pathway, mTOR signaling pathway and Apoptosis including the immune response and cancer. When literature review is conducted, it is seen that this study is the first genome wide IncRNA research conducted on the infected bovine mammary gland tissues with M. bovis agent. Our results have provided bovine mammary gland IncRNA and mRNA resource to understand their roles in the regulation of the immune response against the agent of M. Bovis in the bovine mammary gland tissues.

In vitro infection of Bovine monocytes with Mycoplasma bovis delays apoptosis and suppresses production of IFNγ and TNF-α but not IL-10

Project description:Mycoplasma bovis is one of the major causative pathogens of the bovine respiratory complex disease that is characterized by enzootic pneumonia, mastitis, pleuritis and polyarthritis. M. bovis enters and colonizes the bovine respiratory epithelia through inhalation of aerosol from contaminated air. The nature of the interaction between M. bovis and bovine innate immune system is not well understood. We hypothesized that M. bovis invades blood monocytes and regulates cellular function to support its persistence and systemic dissemination. We used bovine-specific peptide kinome arrays to identify cellular signaling pathways that could be relevant to M. bovis-monocyte interaction in vitro. We validated these pathways using functional, protein and gene expression arrays. Here we show that infection of blood monocytes with M. bovis delays spontaneous or TNF-α/staurosporine-driven apoptosis, activates NF-κβ p65 subunit and inhibits caspase-9 activity. We also report that M. bovis infected bovine monocytes do not produce IFN-γ and TNF-α, although production of IL-10 is elevated. Our findings suggest that M. bovis takes over the cellular machinery of bovine monocytes to prolong bacterial survival and to possibly facilitate subsequent systemic distribution.

RNA sequencing provides exquisite insight into the manipulation of the alveolar macrophage by tubercle bacilli

Project description:Mycobacterium bovis, the agent of bovine tuberculosis, causes an estimated $3 billion annual losses to global agriculture due, in part, to the limitations of current diagnostics. Development of next-generation diagnostics requires a greater understanding of the interaction between the pathogen and the bovine host. Therefore, to explore the early response of the alveolar macrophage to infection, we report the first application of RNA-sequencing to define, in exquisite detail, the transcriptomes of M. bovis-infected and non-infected alveolar macrophages from ten calves at 2, 6, 24 and 48 hours post-infection. Differentially expressed sense genes were detected at these time points that revealed enrichment of innate immune signalling functions, and transcriptional suppression of host defence mechanisms (e.g., lysosome maturation). We also detected differentially expressed natural antisense transcripts, which may play a role in subverting innate immune mechanisms following infection. Furthermore, we report differential expression of novel bovine genes, some of which have immune-related functions based on orthology with human proteins. This is the first in-depth transcriptomics investigation of the alveolar macrophage response to the early stages of M. bovis infection and reveals complex patterns of gene expression and regulation that underlie the immunomodulatory mechanisms used by M. bovis to evade host defence mechanisms.

Key hub and bottleneck genes differentiate the macrophage response to virulent and attenuated Mycobacterium bovis

Project description:Mycobacterium bovis is an intracellular pathogen that causes tuberculosis in cattle. Following infection, the pathogen resides and persists inside host macrophages by subverting host immune responses via a diverse range of mechanisms. Here, a high-density bovine microarray platform was used to examine the bovine monocyte-derived macrophage transcriptome response to M. bovis infection relative to infection with the attenuated vaccine strain, M. bovis Bacille CalmetteM-bM-^@M-^SGuM-CM-)rin. Differentially expressed genes were identified (adjusted P-value M-bM-^IM-$ 0.01) and interaction networks generated across an infection time course of 2, 6 and 24 h. The largest number of biological interactions was observed in the 24 h network, which exhibited small-worldscale-free network properties. The 24 h network featured a small number of key hub and bottleneck gene nodes, including IKBKE, MYC, NFKB1 and EGR1 that differentiated the macrophage response to virulent and attenuated M. bovis strains, possibly via the modulation of host cell death mechanisms. These hub and bottleneck genes represent possible targets for immunomodulation of host macrophages by virulent mycobacterial species that enable their survival within a hostile environment. Affymetrix GeneChipM-BM-. Bovine Genome Arrays were used to examine gene expression from a paired comparison of bovine monocyte-derived macrophages (MDM) after in vitro challenge with Mycobacterium bovis versus M. bovis BCG across a time series of 2 hr, 6 hr and 24 hr post-challenge.
