Project description:Analysis of mRNA-seq reveals difference in gene expression profiles of wild type iBMDM, IRF3-/- iBMDM and IRF7-/- iBMDM infected with ME49, a type II Toxoplasma gondii
Project description:The lack of a comprehensive map of transcription start sites in Toxoplasma gondii has impeded advances in decrypting the molecular mechanisms underlying the regulation of gene expression. Genome-wide approaches for mapping transcription initiation have been instrumental in defining the determinants of transcription initiation in a range of model eukaryotes. We used a protocol for 5′-end RNA sequencing, called RAMPAGE, to sequence the 5′-ends of capped mRNA from ME49 and RH tachyzoites, as well as from ME49 bradyzoites. This allowed us to generate maps of transcription initiation events at single-nucleotide resolution across the asexual stages of the parasite.
Project description:Toxoplasma gondii is a ubiquitous protozoan pathogen able to infect both mammalian and avian hosts. Surprisingly, just three strains appear to account for the majority of isolates from Europe and N. America. To test the hypothesis that strain divergence might be driven by differences between mammalian and avian response to infection, we examine in vitro strain-dependent host responses in a representative avian host, the chicken. Chicken embryonic fibroblasts were cultivated in vitro and infected with different strains of Toxoplasma gondii (Type II = ME49, Type III = CEP); host transcriptional responses were then analyzed at 24 hours post-infection.
