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

Neurons communicate via synapses, where chemicals (such as glutamate) are released to transmit neuronal signals. This proposal is aimed at understanding the molecular mechanisms of neuronal communication and adaptive plasticity, which are essential for normal brain function. The proposed research will combine biophysical, biochemical, molecular and cell biological assays to elucidate the role of a calcium binding protein in controlling glutamate receptor trafficking in neurons. The outcomes will enhance our understanding of how neural plasticity is generated and maintained, knowledge that is critical for our understanding of cellular correlates of information, sensory and motor processing, as well as learning, memory and cognition.

This project aims to investigate how autophagosomes are built during autophagy by using advanced multi-modal imaging and unique gene-edited human cell lines. This project expects to generate new knowledge on how a family of evolutionary conserved proteins regulate autophagosome formation during starvation and stress conditions. Expected outcomes include the development of frontier imaging technologies that can be subsequently utilised for the advancement of any field of cell biology. This should provide significant benefits by placing Australia at the forefront of cell biology technologies and increasing our understanding of how plant and human cells can protect themselves during starvation and stress.

RhoA signaling: the nanoscale mechanisms of mechanochemical regulation. This project aims to elucidate a new paradigm for regulating cell signals at the nanoscale level. Cell signalling involves the coordination of multi-molecular networks at the plasma membrane, the interface between the cell and its external environment. These are often thought to involve the assembly of multimolecular complexes through the action of protein scaffolds. This project will focus on how the contractile regulator, ....RhoA signaling: the nanoscale mechanisms of mechanochemical regulation. This project aims to elucidate a new paradigm for regulating cell signals at the nanoscale level. Cell signalling involves the coordination of multi-molecular networks at the plasma membrane, the interface between the cell and its external environment. These are often thought to involve the assembly of multimolecular complexes through the action of protein scaffolds. This project will focus on how the contractile regulator, anillin, controls RhoA signalling by kinetic regulation. In particular, how nanoscale clustering of anillin by the dynamic actomyosin cytoskeleton modulates RhoA signalling for contractility and tissue homeostasis. The outcomes of this project are first and foremost fundamental understanding of how cells communicate with one another.Read moreRead less
Defining mechanisms behind the formation of hierarchical vascular networks. Blood vessels form complex branched networks composed of arteries, capillaries and veins. The development and maintenance of different vessel systems (arteries and veins) is dependent on cell adherence properties within each vessel, yet how these are established and maintained remains unknown. This project aims to analyse the differences in junctional dynamics between sprouting arteries and veins, and to identify arteria ....Defining mechanisms behind the formation of hierarchical vascular networks. Blood vessels form complex branched networks composed of arteries, capillaries and veins. The development and maintenance of different vessel systems (arteries and veins) is dependent on cell adherence properties within each vessel, yet how these are established and maintained remains unknown. This project aims to analyse the differences in junctional dynamics between sprouting arteries and veins, and to identify arterial and venous signalling networks that make and maintain vessel identity. This project will reveal how adhesiveness is regulated in order to make a hierarchical, functional vascular network, with implications for engineering of functional, vascularised organs in the biotech sector.Read moreRead less

Understanding how cells function in the ‘real-time’ context of a living organism is a key challenge in the new era of cell biology. Using super-resolution light microscopy and state-of-the-art correlative electron microscopy together with model systems, this Fellowship aims to deliver new understandings of cells in their natural environment. Significantly, the project will elucidate how proteins or nanoparticles pass from the bloodstream into tissues and then into cells, and in doing so deliver much-needed knowledge of protein and particle trafficking in situ. Outcomes and benefits include leading-edge fundamental science into the function of cells, education, outreach and building of Australian capacity in high-demand skill sets.Read moreRead less
