Project description:The aim of this study is to look at antigenic variation in recrudescent Plasmodium chabaudi infections and to identify the genes, if any, which allow the parasite to avoid the acquired immune response during recrudescence. This has been done in collaboration with Jean Langhorne at NIMR whose group performed the mouse work and extracted the RNA. This data is part of a pre-publication release.

The closely related species T. muris is a naturally occurring nematode parasite of mice that serves as a remarkably tractable model system for dissecting immune responses and host-parasite relationships. Such studies are of relevance beyond parasitology as helminths have arguably had a significant impact on the evolution of the mammalian immune system. Both Trichuris species reside in the caecum and colon of the host where they burrow their front end for feeding into the intestinal mucosa, thereby breaching the mucus barrier and allowing access of the microflora directly to the epithelium. The interplay of intestinal helminths, the bacterial microflora and the host immune system is currently a research focus in various laboratories (Bancroft et al 2012). This study will study the transcriptional responses of the intestinal mucosa (caecum) from infected and uninfected mice.

Project description:The aim of this study is to characterise gene expression in the rodent malaria intra-erthrocytic development cycle. This will inform two further studies looking at host-parasite interactions in rodent malaria and in comparison to the same stage of human malaria will provide insight into variation in lifecycles between human and rodent malaria.

It is a severely debilitating disease, which is transmitted to humans by black fly. This project aims to undertake high-throughput sequencing of Onchocerca volvulus transcriptome for de novo assembly of transcripts. The main objective of this project is to recognize genes expressed in given life stages.

Project description:Trypanosoma vivax is a major pathogen of domestic cattle and wildlife across sub-Saharan Africa. For many years, the WTSI has had a research interest in developing a genome sequence for T. vivax, as part of a wider programme concerning African trypanosome parasites of Humans and animals. In 2012 a draft genome sequence for T. vivax Y486 was published by the WTSI and our collaborators in comparison with related species, T. brucei and T. congolense. This study identified numerous putative genes in T. vivax that have no known affinity and are therefore species-specific. A related transcriptomic study confirmed that some of these putative genes are transcribed, but lacked accuracy and was based on a single parasite life stage only. Until recently, it has not been possible to culture different T. vivax life stages in refined media. There is now the opportunity to use new approaches to produce whole cell RNA for both insect and bloodstream parasite stages. We sequence stage-specific cDNA and identify stage-specific genes, and compare these features with similar data already available for T. brucei and T. congolense, which display substantial differences in their developmental cycles.

It affects over 200 million people across 74 countries. The complete genome sequence of Schistosoma mansoni was published in 2009, but immune response against this parasite is not well characterized. This study is to investigate the overall immune response, antibody and TCR repertoire of immunologically nave mice, mice infected with S.mansoni and mice challenged with a secondary schistosome infection.RNA-seq data will be used to characterise the systemic immune response of mouse to Schistosoma infection, including both whole-transcriptome sequencing for a global picture of the immune response, and sequencing the lymphocyte antigen receptor genes to get a detailed picture of the adaptive immune response.

Project description:The goal of this project is to understand the etiology and pathology of host-pathogen interaction using high-throughput cellular phenotyping. By combining the expertise in pathogen biology, informatics and stem cell biology across the institute, this project will use targeted genetic modification in mouse embryonic stem cells to identify functions of host genes in innate immunity. We will also explore the biology of mouse embryonic stem cells and their differentiation into immune competent cells. To this end we will generate homozygous and inducible knockout lines in mouse embryonic stem cells, which will be differentiated into immune competent cells, such as macrophages or dendritic cells. These will be subjected to a panel of immune challenge and stimulation assays to characterise the functions of the disrupted genes. To identify new functions for mammalian genes in innate immunity we will:\Generate a panel of homozygous inducible gene knockout mouse ES cell lines working from a list of ca. 80 candidate genes (MGP phenotyping and GWAS hits). \Scale up differentiation protocols for immune challenge and stimulation assays.\Benchmark in vitro differentiated ES cell models against primary immune cells from selected MGP mouse lines and eventually against human iPS cells.\Screen a panel of 30 genetically modified cell lines in immunological challenge and stimulation assays, defining phenotypes at the cellular level by high content imaging, biochemically by assaying cytokine production, and at the molecular level by transcriptome analysis.\Define novel gene functions in innate immunity through network analysis of gene expression data from all challenged cell lines.\In the longer term scale up the production and phenotyping of genetically modified cell lines (mouse or human as appropriate).This data is part of a pre-publication release.
