ATAC-seq Identification of Chromatin Accessibility in Both Human Host Cells and the Parasite Toxoplasma gondii

Project description:To identify accessible chromatin regions in the human host cells during Toxoplasma parasite infection (uninfected, RH-infected and Pru-infected human foreskin fibroblasts) and in the obligate intracellular parasite Toxoplasma gondii (Type 1 RH strain and Type 2 Pru strain), ATAC-seq was performed.

RNAseq of intracellular Toxoplasma gondii treated with Tartrolon E

Project description:Tartrolon E is a pan anti-apicomplexan compound derived from a symbiotic bacteria of shipworms. The mechanism of action of the compound is unknown, and attempts to select parasite mutants resistant to the compound has been unsuccessful. In this study, RNAseq was performed on human foreskin fibroblast cells (HFF) infected with Toxoplasma gondii RH strain and treated with Tartrolon E to identify genes targeted by the compound.

Host gene expression response to Toxoplasma gondii infection is not different between RH?ku80 and RH?ku80?rop5 parasites.

Project description:The normally virulent type-I RH parasite is rendered avirulent when lacking ROP5. The avirulent phenotype is a consequence of interaction with the host innate immune system. We sought to understand if ROP5 alters host gene expression in order to escape host defenses. We saw no gene expression differences between host cells infected with wt (RH?ku80) or RH?ku80?rop5 parasites. We have included uninfected HFF samples that were harvested in parallel with the infected samples. Host gene expression in response to infection with Toxoplasma gondii. Two independent samples per sample type. Three sample types: HFF infected with RH?ku80, HFF infected with RH?ku80?rop5, and uninfected HFF.

Expression data for various strains of Toxoplasma gondii chosen from canonical types (i.e., I,II, and III)

Project description:This study establishes a baseline pattern for RNA expression among canonical strains of Toxoplasma gondii grown in tissue culture without perturbation. Parasites cultured within human foreskin fibroblast (HFF) cells grown with D10 media were scraped and harvested ~8-12 hours prior to host cell lysis. RNA was isolated and applied to a T. gondii Affymetrix array.

Comparative Analysis Reveals Genotype-specific Lyisne Malonylation of Toxoplasma gondii

Project description:Toxoplasma gondii is a protozoan parasite which can infect a wide range of animals, including humans. According to virulence, it is generally divided into three different strains, namely type I (RH strain), type II (PRU strain) and type III (VEG strain). Lysine malonylation (Kmal) is a new type of post-translational modification (PTM), which has been reported to regulate diverse biological pathways in various organisms, including T. gondii. However, there is no knowledge about whether lysine malonylation regulates the virulence of different strains in T. gondii. In this study, for the first time, we identified and quantified lysine malonylation level in three strains of T. gondii. In total, 111 proteins and 152 sites were up-regulated, 17 proteins and sites were down-regulated in RH compared with PRU strains, respectively; 50 proteins and 59 sites were up-regulated, 50 proteins and 53 sites were down-regulated in RH strain compared with VEG strains; 72 proteins and 90 sites were up-regulated, 7 proteins and 8 sites were down-regulated in VEG strain compared with PRU strains. Further analysis indicates that these proteins are involved in many important biological processes and regulating virulence-related functions of T. gondii. These findings provide novel and important resource for the role of lysine malonytion in virulence of T. gondii and provide a new direction for the research of vaccine in T. gondii.

Project description:The closely related protozoan parasites Toxoplasma gondii and Neospora caninum display similar life cycles, subcellular ultrastructure, invasion mechanisms, metabolic pathways, and genome organization, but differ in their host range and disease pathogenesis. Type II (γ) interferon has long been known to be the major mediator of innate and adaptive immunity to Toxoplasma infection, but genome-wide expression profiling of infected host cells indicates that Neospora is a potent activator of the type I (α/β) interferon pathways typically associated with antiviral responses. Infection of macrophages from mice with targeted deletions in various innate sensing genes demonstrates that host responses to Neospora are dependent on the toll-like receptor Tlr3 and the adapter protein Trif. Consistent with this observation, RNA from Neospora elicits type I interferon responses when targeted to the host endo-lysosomal system. While live Toxoplasma fails to induce type I interferon, heat-killed parasites do trigger this response, and co-infection studies reveal that T. gondii actively suppresses the production of type I interferon. These findings reveal that eukaryotic pathogens can be potent inducers of type I interferon and that some parasite species, like Toxoplasma gondii, have evolved mechanisms to suppress this response. Human foreskin fibroblasts (HFF; line BJ-5ta) were cultured to confluency in T25 flasks, infected with one representative of each of the three architypial strains of Toxoplasma gondii: GT1 (type I), Prugniaud (type II) and VEG (type III), or the closely related parasite species, Neospora caninum (strain Nc-Liv). RNA was collected from biological replicates for expression profiling by microarray. Uninfected HFF cells were used as a reference.
