Identification And Chracterization Of Host Cell Receptors For Influenza A Viruses
Funder

Funding Amount
$92,314.00
Summary
Following inhalation, influenza virus infects cells of the immune system and epithelial cells lining the airways. Currently, it is not clear how influenza virus attaches to and infects these cells. This project will use new ways to identify receptors for influenza virus on human epithelial cells and immune cells. The ultimate identification of these receptors would have important implications for the development of new drugs to treat influenza virus infections.
Multiscale Analysis Of Plasma Membrane Microdomains In Health And Disease

Funding Amount
$863,413.00
Summary
The cell surface encloses the cell in a protective barrier but it must also respond to signals coming from outside the cell. To accomplish this, the cell surface is made up of numerous regions each with a specialised role. This proposal aims to examine how lipids and proteins work together to make these specialised regions and aims to understand what goes wrong in diseases such as muscular dystrophy.
A unified model of amino acid homeostasis. This project aims to develop a unified model of amino acid homeostasis in mammalian cells and apply it to brain cells. The model will be underpinned by a mathematical algorithm that allows predicting amino acid levels in the cytosol based on fundamental parameters such as transport and metabolism. This project should provide the significant benefit of enabling the prediction of essential functions such as cell growth and survival.
The Implications Of Focal Adhesion Organization On Signal Transduction

Funding Amount
$565,614.00
Summary
The areas of a cell's attachment to their surroundings are known as focal adhesion. Apart from linking the inside and outside of a cell, focal adhesions act as a communication centre transmitting incoming and outgoing signals. How focal adhesions themselves are organized is currently not known. We propose to adhere cells to model surfaces to control the protein and membrane structure of focal adhesions and measure how focal adhesion structure affects cell communication.
A humanised sensory neuron high-throughput screening platform . Sensory neurons are responsible for converting external stimuli such as touch or temperature into graded electrical signals that allow us to interact with the world around us. However, unlike other cell types, sensory neurons cannot proliferate and thus must be removed from human cadavers, or animals, in order to study their pharmacology and function. This limits our ability to understand neuronal signalling pathways. This project a ....A humanised sensory neuron high-throughput screening platform . Sensory neurons are responsible for converting external stimuli such as touch or temperature into graded electrical signals that allow us to interact with the world around us. However, unlike other cell types, sensory neurons cannot proliferate and thus must be removed from human cadavers, or animals, in order to study their pharmacology and function. This limits our ability to understand neuronal signalling pathways. This project aims to use sensory neurons derived from human stem cells to develop and optimise assays that can be used to study the pharmacology and function of human sensory neurons in vitro. This enhances access to critical model systems and technology platforms and removes the need for isolation of cells from cadavers. Read moreRead less
Regulation of glutamate receptor dynamics in mammalian central neurons. This proposal aims to understand the molecular mechanisms of neuronal communication and how neurons modify their synaptic strength. Although these processes are essential for normal brain function, the precise underlying mechanisms are still not well understood. This project will combine biochemical, molecular and cell biological assays, as well as electrophysiological measurements, to provide mechanistic insights into the m ....Regulation of glutamate receptor dynamics in mammalian central neurons. This proposal aims to understand the molecular mechanisms of neuronal communication and how neurons modify their synaptic strength. Although these processes are essential for normal brain function, the precise underlying mechanisms are still not well understood. This project will combine biochemical, molecular and cell biological assays, as well as electrophysiological measurements, to provide mechanistic insights into the molecular processes that control glutamate receptor trafficking in the postsynaptic compartment. This will elucidate how neural plasticity is generated and maintained, information that is critical for our understanding of sensory processing, learning and memory throughout life.Read moreRead less

The function of the ribbon structure of the Golgi apparatus in vertebrates. The aim of the project is to determine the function of the Golgi ribbon structure in higher order cell functions, including metabolism, cell cycle, and cell polarity in both cultured cells and whole organisms. Understanding of the functions of the Golgi has been restricted to the regulation of glycosylation and membrane transport. However, it is now recognised that the Golgi apparatus feeds into the wiring of a range of ....The function of the ribbon structure of the Golgi apparatus in vertebrates. The aim of the project is to determine the function of the Golgi ribbon structure in higher order cell functions, including metabolism, cell cycle, and cell polarity in both cultured cells and whole organisms. Understanding of the functions of the Golgi has been restricted to the regulation of glycosylation and membrane transport. However, it is now recognised that the Golgi apparatus feeds into the wiring of a range of cellular networks in higher organisms such as cell polarisation, directed migration, metabolism and autophagy. Vertebrates have evolved mechanisms for joining individual Golgi stacks into a ribbon structure. The relevance of this ribbon structure remains a mystery. The project aims to answer this major question in cell biology.Read moreRead less
