Transcription profiling of bovine mammary epithelial cells stimulated with Mycoplasma bovis against untreated controls

Project description:Mycoplasma species are highly contagious pathogens, and intramammary Mycoplasma infection is a serious issue for the dairy industry. The bovine mammary epithelial cells (bMEC) play an important role for the eradication of pathogens which cause intramammary infection, however the effects of M. bovis for immune response of bMEC have not been fully clarified. We examined the transcription profiling of bMEC on the stimulation with M. bovis for 6h (3 stimuli, 3 control).

microRNA identification in the Mycoplasma bovis infected mammary gland tissue in Holstein Friesian cattle

Project description:The immune response associated with mastitis caused by Mycoplasma bovis is a very complicated biological process in several type of cells, including immune cells, mammary epithelial cells and, endothelial cells. Thus, revealing of the microRNAs in the Mycoplasma bovis infected mammary gland tissues is particularly important for the immune response mechanism to Mycoplasma bovis. Firstly, mammary gland tissue samples were collected from Holstein cows and screened for Mycoplasma bovis. Then, total RNA was isolated from mycoplasma bovis infected tissues and RNA sequencing was performed. After bioinformatics analysis, GO and KEGG analysis of target genes of identified microRNAs were conducted. Our results revaled that 24 of the known microRNAs were expressed differently and 13 of the novel microRNAs were expressed differently in Mycoplasma bovis positive tissues. The target genes of these microRNAs were found to be associated with especially inflammation pathways. In conclusion, this study demonstrated that identified miRNAs may be involved in the signaling pathways during mastitis case caused by Mycoplasma bovis.

Transcription profiling of bovine peripheral blood mononuclear cells stimulated with Mycoplasma bovis against untreated controls

Project description:Mycoplasma species are highly contagious pathogens, and Mycoplasma infectious disease are a serious issue for the dairy industry. The bovine peripheral blood mononuclear cells (PBMCs) play an important role for the eradication of pathogens which cause mycoplasmal infection, however the effects of M. bovis for immune response of PBMCs in vitro have not been fully clarified.We examined the transcription profiling of bovine PBMCs on the stimulation with M. bovis for 6h (3 stimuli, 3 control).

Transcriptome profiles of the different expression genes in peripheral blood mononuclear cells (PBMCs) of calves infected with two different virulent Mycoplasma bovis strains

Project description:Mycoplasma bovis (M.bovis) is a critical pathogen of bovines resulting in pneumonia, mastitis, arthritis, etc. To reveal its virulence related factors, a virulent M. bovis HB0801 and its derived vaccine strain P150 were infected calve and the transcriptome profiles of PBMCs were compared by using of the microarray at 7 days after infection. The data postulated the pathogenic mechanism of wild strain and immune mechanism of the attenuated strain to provide clues for the further research of the interaction between M. bovis and its host.

Comprehensive Immunoproteome of Mycoplasma bovis

Project description:This study was aimed to elucidate a global antigenic profile of Mycoplasma bovis (M. bovis) with immunoproteomics, immunoinformatics, and gene expression approaches. The extracts of whole-cell proteins and TX-114 membrane fraction of a Chinese strain M. bovis HB0801 were separated with two dimensional gel electrophoresis (2-DE) and proteins reacting with antisera to M. bovis from experimentally infected calves were detected by MALDI-TOF MS.

Innate immune response of bovine mammary epithelial cells to <i>Mycoplasma bovis</i>.

Project description:Mycoplasma spp. are contagious bacteria, and mycoplasmal mastitis is a serious productivity problem on dairy farms. Bovine mammary epithelial cells (bMECs) have an important role in the elimination of pathogens, but the effect of Mycoplasma bovis on bMECs has not been fully described. To elucidate the immune response against intramammary infection by M. bovis, we undertook microarray analysis to examine and profile mRNA expression in bMECs after stimulation with M. bovis. We also compared the effects of M. bovis, Staphylococcus aureus, and Escherichia coli on immune-related mRNA expression in bMECs. Transcriptome analysis indicated a significant decrease in the level of mRNA-encoding lysine-specific demethylase 4D, suggesting that the immune response is suppressed by a decrease in histone demethylase activity. Interleukin (IL)-1β, IL-6, tumor necrosis factor alpha, toll-like receptor (TLR) 2, and TLR4 mRNA expression levels were significantly increased in bMECs stimulated with heat-killed M. bovis, but the expression levels were lower than those following stimulation by heat-killed S. aureus or E. coli. Our results suggest that M. bovis weakly affects mRNA expression in bMECs compared to the effects of E. coli or S. aureus. Moreover, live M. bovis may induce suppression of the immune response in bMECs.

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.
