Activation of invasion in Toxoplasma. Host cell invasion is critical for the establishment and maintenance of infection by the single-celled parasite Toxoplasma gondii, the causative agent of Toxoplasmosis. This project will use the latest molecular techniques to understand how invasion is activated and will define a new set of drug targets to treat Toxoplasmosis and related diseases.
Dynamic regulation of cell signalling scaffolds.

How Do Mutations In Autophagy Receptors Cause FTD And ALS?

Summary
As cells age the "garbage disposal" process within cells slows down, becoming less functional. In inherited forms of dementia the genes involved often code for damaged proteins that "clog up" the disposal system or directly affect the “garbage men”. These defective garbage men genes include SQSTM1/p62, OPTN, VCP and UBQLN2. We will determine how these defective genes lead to build up of garbage in neuronal cells and how leads to disease.

Summary
Exercise is one of the best prevention and treatment strategies for all major human diseases. Despite these well documented advantages, we still do not know exactly how exercise produces these benefits at the molecular level. A comprehensive understanding of this will lead to new avenues to treat many diseases. This project will monitor thousands of molecular changes that occur in human muscle biopsies following exercise and create the world’s first molecular blueprint of exercise.
The cell is the building block of life. This proposal focusses on the surface of the cell, the plasma membrane, and specialised structures called caveolae that are an abundant feature of animal cells. Altered caveolae are a feature of many human disease conditions. In this proposal we will address the function of caveolae. We will test the idea that proteins are released from caveolae into the cell when cells are stressed forming a novel signalling pathway disrupted in disease.

Summary
Cytokines are hormones that regulate blood cell production and function. The research proposed in this application focuses on the biological roles and biochemical mechanisms of action of an important family of proteins that control the actions of cytokines, thereby allowing their beneficial effects in coordinating oxygen transport, blood clotting and responses to infection, while preventing the harmful effects of excess responses, such as myeloproliferative diseases or autoimmunity.
Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innov ....Mechanisms of memory function involving site-specific tau phosphorylation. This project aims to understand the molecular principles that facilitate encoding, maintenance and retrieval of memories in the brain. To store memories in brain circuits, electrical and chemical signals are crucial. Brain cells can integrate signals into biochemical modifications of intracellular proteins. The nature of the protein modifications that represent memory within brain cells is unknown. This project uses innovative genome editing, mathematical modelling and proteomic approaches, to study how biochemical modifications of a key protein called tau help encode and retrieve memories. These molecular insights will make a significant advance in the current understanding of a brain function that is essential to all human activities.Read moreRead less

The core inflammasome as a model for caspase activation. This project aims to change the paradigm for the structure of the active inflammasome. Inflammasomes activate caspases, enzymes central to cell death and inflammatory processes. The current concept of inflammasomes is that caspases are recruited into a single massive protein complex seen as a “speck” in the cell. This project proposes the speck is a terminal stage, after the major enzymatic activity is over. This project aims to purify sma ....The core inflammasome as a model for caspase activation. This project aims to change the paradigm for the structure of the active inflammasome. Inflammasomes activate caspases, enzymes central to cell death and inflammatory processes. The current concept of inflammasomes is that caspases are recruited into a single massive protein complex seen as a “speck” in the cell. This project proposes the speck is a terminal stage, after the major enzymatic activity is over. This project aims to purify smaller early stage inflammasome complexes, for structural analysis. The outcome will be a clearer understanding of processes of caspase activation and inflammasome formation. This will provide significant benefits, such as improve our understanding of processes of cell death and innate immunity, and train students.Read moreRead less

Protein phosphorylation is a dynamic process regulated by both protein kinases and protein phosphatases. While the role of kinases in cellular functions are well defined, the roles of protein phosphatases are not well understood. Using a range of laboratory models this project aims to discover the function of the phosphatase PP2A, in cell proliferation, survival, differentiation and DNA damage repair. The anticipated outcome is an improved understanding of all stages of mammalian development. This will provide significant benefits in the biotechnology, chemical and pharmaceutical industries.Read moreRead less
