Strain-dependent host responses in chicken embryonic fibroblasts infected with Toxoplasma gondii [ME49, CEP, and Mock]

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.

RNA-seq data analysis of TgAP2XII-1 on Toxoplasma gondii merozoites development [ME49 XII-1 RNAseq]

Project description:To investigate transcriptional role of TgAP2XII-1 on type II Toxoplasma gondii (ME49 Tir1), an auxin inducible degron system was introduced to control the protein expression of TgAP2XII-1 and the target protein could be totally degradated in 3h after adding IAA.

RESTRICTION checkpoint controls bradyzoite development in Toxoplasma gondii

Project description:The Toxoplasma gondii G1 RESTRICTION checkpoint operates the switch between parasite growth and differentiation. The Cdk-related G1 kinase TgCrk2 forms alternative complexes with atypical cyclins (TgCycP1, TgCycP2 and TgCyc5) in the rapidly dividing developmentally incompetent RH and slower dividing developmentally competent ME49 tachyzoites and bradyzoites. The TgCycP1 expression interferes with bradyzoite differentiation. The TgCycP2 regulates G1 in the developmentally competent ME49 but not in the developmentally incompetent RH tachyzoites. Examination of TgCycP2 and TgCyc5 in alkaline induced and spontaneous bradyzoite differentiation (rat embryonic brain cells) models confirmed TgCycP2 role in bradyzoite replication and revealed that stress induced TgCyc5 is critical for efficient tissue cyst maturation.

Anti-tumor Effect and Action Mechanism of Exosomes Derived from Toxoplasma gondii-Infected Dendritic Cells in Mice Colorectal Cancer

Project description:Toxoplasma gondii is an obligate intracellular protozoan with anti-tumor activity against a variety of cancers. However, the therapeutic effect of T. gondii on colorectal cancer is unclear, and using direct Toxoplasma infection in immunotherapy involves safety concerns. This study investigated the anti-tumor effect and mechanism of exosomes derived from dendritic cells (DC) infected with T. gondii (Me49-DC-Exo). We used the density gradient centrifugation to isolate exosomes from uninfected DCs (DC-Exo) and T. gondii Me49-infected DCs (Me49-DC-Exo). The isolated exosomes were identified by transmission electron microscopy, nanoparticle tracking analysis, and western blotting. Me49-DC-Exo significantly inhibited tumor growth and reduced the proportion of M2 macrophages in the blood of tumor-bearing mice. In vitro, Me49-DC-Exo suppressed macrophage (RAW264.7) polarization to M2 phenotype. miRNA sequencing revealed that multiple miRNAs in Me49-DC-Exo were differentially expressed compared with DC-Exo. miR-182-5p, miR-155-5p, miR-125b-2-3p, and miR-155-3p were up-regulated, while miR-9-5p was significantly down-regulated. Transfecting mimics or inhibitors of these differential miRNAs into RAW264.7 cells showed that miR-155-5p promoted M1 macrophage polarization while inhibiting M2 macrophage polarization. Bioinformatics prediction and dual-luciferase reporter assay confirmed the suppressor of cytokine signaling 1 (SOCS1) as a direct target of miR-155-5p. Silencing SOCS1 gene expression in RAW264.7 cells increased CD86 + CD206 - M1 macrophage proportion and inducible nitric oxide synthase and tumor necrosis factor-α mRNA levels. However, arginase1 and transglutaminase 2 expression levels decreased. These results suggest that the exosomes inhibit macrophage polarization to M2 phenotype and regulate SOCS1 expression by delivering functional miR-155-5p. These findings provide new ideas for colorectal cancer immunotherapy.

MicroRNA expression profile of porcine alveolar macrophages infected with Toxoplasma gondii

Project description:Purpose: Porcine alveolar macrophage was infected by T. gondii including Rh strain and Me49 strain. We want to explore the change of miRNAs after infected with T. gondii in porcine alveolar macrophages. Results: Our study generated six mi RNA expression profiles from macrophages which infect with Rh strain and Me49 and control group in different time. Compare with T. gondii-infected and uninfected with T. gondii, 81 differentially expressed mi RNAs were identified, including 36 novel mi RNAs and 45 mature mi RNAs.

Genome-wide mapping of transcription initiation in the asexual stages of 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.
