Summary
Pathogenic bacteria are master manipulators of the inflammatory signalling pathways designed to thwart them. Understanding how they do this will allow us to develop drugs that limit their ability to infect. We have shown that pathogenic bacteria inject a protein called EspL into human cells to promote the destruction of a family of human proteins, called RIP Kinases (RIPK), that co-ordinate the inflammatory response and aim now to discover how EspL causes RIPK degradation and thereby promotes in ....Pathogenic bacteria are master manipulators of the inflammatory signalling pathways designed to thwart them.

Why Is The Hijacking Of A Human Erythrocyte Signalling Pathway Essential For Malaria Infection?

Summary
Malaria drug resistance is spreading and the world needs cost-effective new drugs. We found 2 human enzymes, known targets of cancer chemotherapy, to be key for parasite survival in red blood cells. We aim to understand why these human proteins are crucial for the parasite and to identify new human proteins hijacked by malaria. This will open exciting options for antimalarial drug discovery: to harness funds invested in cancer drugs by targeting proteins with dual roles in cancer and malaria.
Suppression Of Immunity By The Malaria Parasite Antigen Plasmodium Falciparum Erythrocyte Membrane Protein-1 (PfEMP-1)

Summary
The malaria parasite P. falciparum infects red blood cells and makes the cells put on their surface a protein called PfEMP-1. The parasite can effectively “hide” by constantly changing this protein and making it unrecognizable by the immune system. PfEMP-1 can also suppress the immune system so that it can’t respond adequately to infection. Therefore, understanding PfEMP-1 function is important. I will investigate how PfEMP-1 can do this by looking at its cross talk with the immune system.
