Summary
The single-celled parasite Toxoplasma gondii is the cause of Toxoplasmosis and is an important basis of eye disease, congenital birth defects and illness in immunocompromised individuals. To perpetuate infection T. gondii moves through tissue and invades host cells using a molecular motor, termed the 'glideosome'. We will reveal how the glideosome produces the force required for movement and characterise its critical features. Our work will provide a foundation in which to model novel drugs that ....The single-celled parasite Toxoplasma gondii is the cause of Toxoplasmosis and is an important basis of eye disease, congenital birth defects and illness in immunocompromised individuals.

Summary
Toxoplasma gondii causes a globally important zoonotic disease. It is transmitted by cats, and finds its way into our food chain via infected meat and contaminated water. We have used a unique functional genomics pipeline to discover proteins crucial for reproduction of Toxoplasma in the cat. We will now test combinations of these proteins to immunise cats and prove that we can develop a vaccine that blocks transmission of this highly significant parasitic disease.
Functional Dissection Of Invasion Motor Regulation In Toxoplasma Gondii

Summary
The single-celled intracellular parasite Toxoplasma gondii is the cause of Toxoplasmosis and can be the basis of illness in immunocompromised individuals, eye disease and congenital birth defects. After host cell recognition Toxoplasma needs to activate the invasion machinery to establish a successful infection. We will reveal, at the molecular level, how Toxoplasma achieves this and then screen for drugs that inhibit this process. Compounds identified in this project could act as lead compounds ....The single-celled intracellular parasite Toxoplasma gondii is the cause of Toxoplasmosis and can be the basis of illness in immunocompromised individuals, eye disease and congenital birth defects.
