The pattern generated by X-rays scattering from enzyme crystals CHAGAS' DISEASE Chagas' disease is spread by bites from beetle-like bugsMany patients do not realise they have been infectedDrugs are toxic and only cure some patients in the early stages of infection
"We also need to improve our understanding of parasite biology - how they work, how they stay alive, what makes them tick essentially."We also need to improve our understanding of parasite biology - how they work, how they stay alive, what makes them tick essentially.
"That leads to the second stage of the research, which is how do we stop them working and how we can develop the chemical tools which will do just that.""That leads to the second stage of the research, which is how do we stop them working and how we can develop the chemical tools which will do just that."
The scientists want to find out how enzymes in the parasites protect them in the human immune system.The scientists want to find out how enzymes in the parasites protect them in the human immune system.
The team will build a detailed picture of the chemical structure by shining X-rays through crystals made from the enzymes.The team will build a detailed picture of the chemical structure by shining X-rays through crystals made from the enzymes.
That information with be used to try and develop new drugs for malaria and tuberculosis. That information will also be used to try and develop new drugs for malaria and tuberculosis.
