Chemo-sensation in Ascaris infection. This project aims to show the role of chemo-sensation as an equally important target for worm control, and explore pathways to prevent infection. Parasitic worms cost global food/textile industry more than $100 billion dollars per year, and cause disease in more than 1 billion people and domesticated animals world-wide.

This project aims to show the role of chemo-sensation as an equally important target for worm control, and explore pathways to prevent infection. Parasitic worms cost global food/textile industry more than $100 billion dollars per year, and cause disease in more than 1 billion people and domesticated animals world-wide. This project will use a combination of imaging, systems biology, chemical biology and microfluidic methods to provide significant benefits, such as exploring Ascaris chemo-sensation during larval migration, identify the key host queues and parasite genes regulating this process, and probe helminth chemosensation as a novel target for anti-parasitic treatments.Read moreRead less
Molecular insights into bacterial metal ion homeostasis and toxicity. This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity. Metal ions are essential to all forms of life, and half of all proteins use metal ions for cellular chemical processes. However, how cells precisely balance sufficient metal ions for essential cellular chemistry without ....Molecular insights into bacterial metal ion homeostasis and toxicity. This project aims to measure bacterial cellular metal concentrations, elucidate mechanisms cells use to adapt to changing extracellular metal concentrations, and reveal the molecular targets of metal toxicity. Metal ions are essential to all forms of life, and half of all proteins use metal ions for cellular chemical processes. However, how cells precisely balance sufficient metal ions for essential cellular chemistry without accumulating a toxic excess (metal homeostasis) is poorly understood. Discovering the roles of metal ions in bacterial cells will be key to defining the chemical biology of living systems and will provide information essential to understanding how microbes adapt to changing environments.Read moreRead less
New molecular tools to study the mechanisms of bacterial metal homeostasis. This project aims to provide new insight into how metal ion uptake is regulated. It will precisely measure the cellular concentrations of metal ions, reveal the roles of metal ions in essential cellular processes, and identify the molecular targets of metal toxicity. Metal ions are essential to all forms of life and are used by up to half of all proteins to facilitate cellular chemical processes. The intended outcome of ....New molecular tools to study the mechanisms of bacterial metal homeostasis. This project aims to provide new insight into how metal ion uptake is regulated. It will precisely measure the cellular concentrations of metal ions, reveal the roles of metal ions in essential cellular processes, and identify the molecular targets of metal toxicity. Metal ions are essential to all forms of life and are used by up to half of all proteins to facilitate cellular chemical processes. The intended outcome of the research is to provide new fundamental knowledge of the roles of metal ions in bacterial cells; knowledge that will be key to defining the chemical biology of living systems and will provide information essential to understanding how microbes adapt to changing environments.Read moreRead less

Summary
Targeting cell death pathways in parasites. Schistosomiasis is a disease caused by parasitic worms. Due to the potential for drug resistance, new drugs are needed. This project aims to identify the components needed for parasite survival based on a cell death pathway in schistosomes. Neutralising the activities of these proteins should cause parasite death, providing a new treatment strategy.
