Project description:EMG produced TPA metagenomics assembly of the Lime was injected to acid sulfate soils with aim to balance the acidity. The indigenous microbial communities before and after injection were investigated. (Effects of lime injection on the microbial community in acid sulfate soils) data set
Project description:An Infinium microarray platform (GPL28271, HorvathMammalMethylChip40) was used to generate DNA methylation data from blood samples in two equid species: Somali wild ass and Grevy's zebra. n=12 blood samples
Project description:Precise immunological mechanisms of mRNA vaccines have still not been fully elucidated, especially the initial immune responses at the injection site. Here, by constructing a single-cell atlas of injection site responses of mRNA vaccine, we show that stromal inflammatory responses and type I interferon responses dominate initial transcriptional reactions elicited by mRNA vaccines at the injection site. Tracking down the fates of the delivered mRNA revealed that injection site fibroblasts are highly enriched with the delivered mRNA, and they express IFN-β specifically in response to the mRNA component, not to the LNP. Accordingly, migratory dendritic cells highly expressing interferon stimulated genes (mDC_ISG) were found specifically in muscle and draining lymph nodes of mRNA vaccine injected mice, compared to the empty LNP injected mice. Co-administration of IFN-β and LNP robustly induced mDC_ISGs at the injection site and substantially enhanced antigen-specific CD8 T cell responses. Collectively, these data elucidate earliest mechanisms of the mRNA vaccine and highlight the underappreciated immunogenic role of the mRNA component in the mRNA vaccine.
Project description:Background: Witches’ broom disease of Mexican lime (Citrus aurantifolia L.), which is caused by the phytoplasma “Candidatus Phytoplasma aurantifolia”, is a devastating disease that results in significant economic losses. Plants adapt to abiotic stresses by regulating gene expression at the transcriptional and post-transcriptional levels. MicroRNAs (miRNAs) are a recently identified family of molecules that regulate plant responses to environmental stresses through post-transcriptional gene silencing. Methods: Using a high-throughput approach to sequence small RNAs, we compared the expression profiles of miRNAs in healthy Mexican lime trees and in plants infected with “Ca. Phytoplasma aurantifolia”. Results: Our results demonstrated the involvement of different miRNAs in the response of Mexican lime trees to infection by “Ca. Phytoplasma aurantifolia”. We identified miRNA families that are expressed differentially upon infection with phytoplasmas. Most of the miRNAs had variants with small sequence variations (isomiRs), which are expressed differentially in response to pathogen infection. Conclusions: It is likely that the miRNAs that are expressed differentially in healthy and phytoplasma-infected Mexican lime trees are involved in coordinating the regulation of hormonal, nutritional, and stress signalling pathways, and the complex interactions between them. Future research to elucidate the roles of these miRNAs should improve our understanding of the level of diversity of specific plant responses to phytoplasmas.
Project description:We developed and performed LIMe-ID to simultaneously measure lamina association and DNA methylation in one experimental workflow. We then conducted LIMe-ID following perturbations of PRC2 to better understand the influence of H3K27me3 on lamina association.
