Mechanisms And Targets Of Antibody-complement Interactions That Neutralize Malaria

Summary
Our project aims to identify immune mechanisms that neutralize malaria from the moment of inoculation by a mosquito, before infection can become established to prevent the development of malaria disease. Furthermore, we will discover specific targets of protective immune responses. We expect this project will provide major new advances in our knowledge of human immunity to P. falciparum malaria, one of the world’s most significant causes of mortality and morbidity, and we will use this knowledge
Phagocytic Clearance And Immune Activation In Malaria

Summary
Macrophage white blood cells clear malaria infected cells by eating them, by three routes- by recognising ANTIBODIES or COMPLEMENT on the cell surface, or by the cell BINDING directly to the macrophage. Each has different results, such as amounts of cytokines produced. Cytokines clear malaria; in excess they can cause fatal immune pathology. We will investigate how variations in amount of antibody and complement and route of uptake of malaria infected cells might determine malaria outcome.
Scabies Mite Proteins As Targets For The Development Of New Therapeutics

Summary
Scabies and associated bacteria disease (pyoderma) are a significant health burden, with pyoderma implicated in rheumatic fever and heart disease. Investigations of the mechanism underlying scabies and bacteria disease links, identified scabies proteins inhibiting the human complement system. The inhibition prevents mite damage and promotes growth of bacteria. This proposal aims to elucidate the interaction between scabies, bacteria and the human host, in order to design new therapeutics.
Identification And Development Of Proteins Which Interact With The Innate Immune System As Malaria Vaccine Candidates

Summary
Parasites causing malaria live inside red blood cells. Some human proteins act in a chain reaction to destroy infected cells. Although these proteins recognise parasite-infected cells and the chain reaction starts, the infected cells are not destroyed due to parasite proteins which inhibit the human proteins. A vaccine could induce antibodies which block the parasite proteins inhibiting the human proteins so the immune system can function normally and kill infected cells, thus stopping malaria.
