Serum Response Factor Regulates Immediate Early Host Gene Expression in Toxoplasma gondii-Infected Host Cells

Toxoplasma gondii is a wide spread pathogen that can cause severe and even fatal disease in fetuses and immune-compromised hosts. As an obligate intracellular parasite, Toxoplasma must alter the environment of its host cell in order to establish its replicative niche. This is accomplished, in part, by secretion of factors into the host cell that act to modulate processes such as transcription. ...

Toxoplasma gondii and the host cells.

The protozoan Toxoplasma gondii, described by Nicolle and Manceaux in 1908, is a ubiquitous and cosmopolitan parasite that infects a wide range of mammal and bird species with high prevalence. The biological success of T. gondii is associated with the formation of a specific relationship between the parasite and host cells leading to the establishment of a latent, chronic infection. During prim...

Increased Expression of Toxoplasma Gondii GRA1 Suppresses Host Cell Apoptosis

Suppression of host cell apoptosis enable Toxoplasma gondii to proliferate, but the mechanism is not well understood. We explore the relationship between the expression of T. gondii dense granule protein 1 (GRA1) and host HeLa cell apoptosis. We inserted the T. gondii gra1 coding gene into a pET32a vector and produced recombinant GRA1 (rGRA1) in E. coli Rosetta strain. We then immunized rabbits...
