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.
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.
Project description:Expression profile microarray of human foreskin fibroblast cell comparing control untreated HFF cell with HFF cell infected with ME49 strain.Study on Toxoplasma gondii infection of HFF cell LncRNAs expression, for further studies on the differential exprssion of LncRNAs in HFF cell against the infection of Toxoplasma gondii research provide the basic function.
