Project description:Trichuris muris is very closely related to the human parasite T. trichiura sharing cross reactive antigens. Moreover, it is a remarkably tractable model system for dissecting immune responses and host parasite relationships and is actively being investigated in a number of laboratories worldwide. T. muris is a naturally occurring nematode parasite of mice which resides in the caecum and colon and has a direct oral faecal life cycle. High-throughput sequencing of Trichuris muris transcriptome for de novo assembly of transcripts. The main objective of this project is to recognize genes expressed in given life stages. This data is part of a pre-publication release.

Project description:We analysed the exosomes secreted by the nematode Trichuris muris. Two replicates of exosomes were analysed using a 5600+ mass spectrometer
Project description:We measured the gene expression differences in germinal centre B cells from day 13 Trichuris muris-infected mice in which MLL1 is conditionally deleted in mature B cells
Project description:The intestine is a site of diverse functions including digestion, nutrient absorption, immune surveillance, and microbial symbiosis. As such, intestinal homeostasis is vital for overall wellbeing. Faecal microRNAs (miRNAs) offer valuable non-invasive insights into the transcriptional state of the intestine. However, typical faecal miRNA yields and profiles remain incompletely characterised. Here, we develop an optimised protocol for faecal miRNA detection, and describe a reproducible murine faecal miRNA profile across several studies by performing a meta-analysis. By examining faecal miRNA changes during chronic infection with the gastrointestinal helminth, Trichuris muris, we identify the altered expression of miRNAs associated with fibrosis, barrier integrity and wound healing. Fibrosis was confirmed in vivo, suggesting a role for these miRNAs in regulating wound healing during chronic infection where the production of classical wound healing Th2 cytokines are low. Further implementations of this technique can identify novel hypotheses and therapeutic strategies in diverse disease contexts.
Project description:We analysed the excretory/secretory (ES) products and the exosomes secreted by the nematode Trichuris muris. Two batches of ES and Optiprep fractions of exosomes were analysed using a 5600+ mass spectrometer
