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.

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.

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.

Transcription profiling of bovine neutrophils 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 neutrophils play an important role for the eradication of pathogens which cause mycoplasmal infection, however the effects of M. bovis for immune response of neutrophils have not been fully clarified. We examined the transcription profiling of bovine neutrophils on the stimulation with M. bovis for 3h (3 stimuli, 3 control).

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.

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).

Comparative metabolomics of Mycoplasma bovis and Mycoplasma gallisepticum reveals fundamental differences in active metabolic pathways and suggests novel gene annotations

Project description:Mycoplasmas are simple, but successful parasites that have the smallest genome of any free-living cell and are thought to have a highly streamlined cellular metabolism. Here we have undertaken a detailed metabolomic analysis of two species, Mycoplasma bovis and Mycoplasma gallisepticum, which cause economically important diseases in cattle and poultry, respectively. Untargeted GC/MS and LC/MS analyses of mycoplasma metabolite extracts revealed significant differences in the steady state levels of many metabolites in central carbon metabolism, while 13C stable isotope labelling studies revealed marked differences in carbon source utilization. These data were mapped onto in silico metabolic networks predicted from genome wide annotations. The analyses elucidated distinct differences, including a clear difference in glucose utilisation, with a marked decrease in glucose uptake and glycolysis in M. bovis compared to M. gallisepticum, which may reflect differing host nutrient availabilities. The 13C-labeling patterns also revealed several functional metabolic pathways that were previously unannotated in these species, allowing us to assign putative enzyme functions to the products of a number of genes of unknown function, especially in M. bovis. This study demonstrates the considerable potential of metabolomic analyses to assist in characterising significant differences in the metabolism of different bacterial species, and in improving genome annotation.
