Project description:Dendritic cells (DC) play a pivotal regulatory role in activation of the innate as well as the adaptive part of the immune system by responding to environmental microorganisms. We have previously shown that some lactobacilli strains induce a strong production of the pro-inflammatory and Th1 polarizing cytokine IL-12 in DC. Contrary, bifidobacteria do not induce IL-12, but are able to inhibit the IL-12 production induced by lactobacilli. In the present study, genome wide microarrays were used to investigate the maturation and gene expression pattern murine bone marrow derived DC stimulated with Lactobacillus acidophilus NCFM and Bifidobacterium bifidum Z9. L. acidophilus NCFM strongly induced expression of interferon (IFN)-β, multiple virus defence genes, and cytokine and chemokine genes related to both the adaptive and the innate immune response. Contrary, B. bifidum Z9 mostly up-regulated genes encoding cytokines and chemokines related to the innate immune response. Moreover, B. bifidum Z9 inhibited the expression of the genes initiating the adaptive immune response induced by L. acidophilus NCFM and had an additive effect on genes of the innate immune response and some Th2 skewing genes. The gene encoding Jun dimerization protein 2 (JDP2), a key regulator in cell signalling, was one of the few genes only induced by B. bifidum Z9. Blocking of the JNK1/2 pathway completely inhibited the gene expression of Ifn-β. We suggest that B. bifidum Z9 employs an active mechanism to inhibit induction of genes in DC triggering the adaptive immune system and that JPD2 is involved in the regulatory mechanism.

In the experiment saline control, Lactobacillus acidophilus NCFM, Bifidobacterium bifidum Z9 or both bacteria were were added to murine dendritic cells and stimulated for 10 hours. Experiments were run in triplicates and analyzed in a Two-way ANOVA design.

Project description:To identify the putative salivary tPA activator, we fractionated salivary proteins by size-exclusion chromatography and identified fraction Z8 as the strongest tPA activator, whereas the adjacent fractions Z7 and Z9 activated tPA at lower levels. Mass spectrometry analysis of these fractions identified a total of 152 unique proteins.

Project description:Plant growth-promoting rhizobacteria (PGPR) have been reported to influence plant growth, yield, and nutrient uptake by an array of mechanisms. Uncovering the behavioral dynamics of PGPR is one of the most important issues necessary for understanding their functional performances. In this study, strain NJAU-Z9 which was found to possess complex functions and efficient rhizospheric colonization ability was selected from plenty of bacterial strains isolated randomly from the pepper rhizosphere soil and identified as Bacillus velezensis. Repeated seedling nursing tests performed absolute growth-promoting advantage for the novel isolated strain. After that, primers for the quantitative detection were designed based on its whole genome sequence (WGS), and a real-time PCR method was utilized to explore strategies for monitoring the strain in natural soil and in the pepper rhizosphere. Results showed based on the whole genome, two primers were identified as NJAU-Z9-specific quantitative PCR primers. Two seasonal pot experiments demonstrated that strain NJAU-Z9 effectively colonized the rhizosphere measured by the novel abundance detecting strategy, improved plant growth, and showed a positive correlation between bacterial number and biomass. This study offers a strategy based on a real-time PCR method for directly monitoring B. velezensis strain NJAU-Z9 in the soil and the rhizosphere and provides a reference for the quantitative study of other PGPR strains based on WGSs.
