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:Background: Parasitic helminths influence the composition of the gut microbiome. However, the microbiomes of individuals living in helminth-endemic regions are understudied. The Orang Asli, an indigenous population in Malaysia with high burdens of the helminth Trichuris trichiura, display microbiotas enriched in Clostridiales, an order of spore-forming obligate anaerobes with immunogenic properties. We previously isolated novel Clostridiales that were enriched in these individuals and found that a subset promoted the Trichuris life cycle. In this study, we aimed to further characterize the functional properties of these bacteria.Results: Clostridiales isolates were profiled for their ability to perform 57 enzymatic reactions and produce short chain fatty acids (SCFAs) and hydrogen sulfide, revealing that these bacteria were capable of a range of activities associated with metabolism and host response. Consistent with this finding, monocolonization of mice with individual isolates identified bacteria that were potent inducers of regulatory T cell (Treg) differentiation in the colon. Comparisons between variables revealed by these studies identified enzymatic properties correlated with Treg induction and Trichuris egg hatching.

Project description:Helminth infection may have the potential to suppress intestinal inflammation in inflammatory bowel diseases. Ulcerative colitis is more common in developed countries than in developing countries endemic for helminth infections. There are animal models, as well as clinical trials, suggesting therapeutic effects of experimental helminth infection. Here, we provide a comprehensive molecular portrait of dynamic changes in the intestinal mucosa of an individual who infected himself with Trichuris trichiura to treat his symptoms of ulcerative colitis. Genes involved in carbohydrate and lipid metabolism were upregulated in helminth-colonized tissue, while tissues with active colitis showed upregulation of proinflammatory genes such as IL-17, IL13RA2, and CHI3L1. T. trichiura colonization of the intestine may reduce symptomatic colitis by promoting goblet cell hyperplasia and mucus production through TH2 cytokines and IL-22. By better understanding the physiological effects of helminth infection, new therapies for ulcerative colitis could be identified. This is the third (out of three) series of arrays from this patient from a colonoscopy in 2009 when the patient was in remission.
