Summary
Cellular responses to nanoparticles from cells on micropatterned surfaces. The mechanisms underlying cell-nanoparticle interactions remain largely unknown. It has hampered the design and development of innovative nano devices to be used for drug delivery, biomarkers and diagnostics. This project aims to explore the influences of cell size, density, geometry, intercellular communication and substrate properties on cell-nanoparticle interactions. A micropatterning technology is applied to precisel ....Cellular responses to nanoparticles from cells on micropatterned surfaces. The mechanisms underlying cell-nanoparticle interactions remain largely unknown. It has hampered the design and development of innovative nano devices to be used for drug delivery, biomarkers and diagnostics. This project aims to explore the influences of cell size, density, geometry, intercellular communication and substrate properties on cell-nanoparticle interactions. A micropatterning technology is applied to precisely control cell behaviour and provide a novel in vitro cellular model for nanoparticle studies. This project aims to significantly improve the understanding of cell-nanoparticle interactions to provide new insight into nanoparticle design and improve the efficacy of nano devices.Read moreRead less
Microglia and the inflammation spectrum - not just good or bad. Cell-mediated tissue clearance following brain injury is a universal mechanism. However, our understanding of the cells that perform these tasks is very limited. Our project will characterise this inflammatory response at a single-cell level using the zebrafish spinal cord as a versatile experimental model. The project is expected to strongly contribute to the molecular understanding of the mechanisms underlying debris removal and w ....Microglia and the inflammation spectrum - not just good or bad. Cell-mediated tissue clearance following brain injury is a universal mechanism. However, our understanding of the cells that perform these tasks is very limited. Our project will characterise this inflammatory response at a single-cell level using the zebrafish spinal cord as a versatile experimental model. The project is expected to strongly contribute to the molecular understanding of the mechanisms underlying debris removal and will advance innovative technologies that facilitate intellectual progress in neuroscience. It will produce new insights into the process of neuronal degeneration, promote Australia’s growing reputation as a global leader in neuroscience, and provide high quality training for early career researchers.Read moreRead less
Synergistic nanostimulation of nerve cells using atomic force microscopy technology. The research will develop multifunctional nanoelectrodes for neural prosthetic devices of the future. They will be smaller and more effective, enabling integration with single neural networks in the body, to improve the clinical treatment of severe neurological disorders and loss of sensory (hearing and vision) and motor functions.
Improved effectiveness of cochlear implants through new simultaneous stimulation techniques. Cochlear implants have brought the gift of hearing to 250,000 people worldwide and are an excellent example of Australian innovation. This project will examine an improved "high fidelity" stimulation strategy with the objective of defining a safe stimulus range for clinical use and providing a commercial advantage for Cochlear Ltd.
PET imaging of learning-related plasticity in awake behaving rats. The objective of the project is to combine an investigation of basic learning paradigms with functional Positron emission tomography (PET) imaging in rats in order to answer critical questions about the neurobiological basis of learning and decision-making in the brain. MicroPET technology provides PET images without the confounds induced by anaesthesia. Using this technology, the project intends to observe whole-brain changes in ....PET imaging of learning-related plasticity in awake behaving rats. The objective of the project is to combine an investigation of basic learning paradigms with functional Positron emission tomography (PET) imaging in rats in order to answer critical questions about the neurobiological basis of learning and decision-making in the brain. MicroPET technology provides PET images without the confounds induced by anaesthesia. Using this technology, the project intends to observe whole-brain changes in dopamine neurotransmission in awake, behaving rats while they learn to predict motivationally relevant outcomes based on environmental cues and on their own actions (ie during Pavlovian and instrumental conditioning, respectively). The outcomes of this research may improve our understanding of the neural changes responsible for debilitating disorders of the brain and mind.Read moreRead less
Development of an electrode for stimulation of a transplanted neosphincter. This project aims to develop a novel electrode as an integral component of a new treatment for severe stress urinary incontinence. Treatments for severe stress urinary incontinence are associated with complications and are not completely effective. The new electrode is designed to be activated by an implanted stimulator to control an innervated smooth muscle graft (the neosphincter) to regulate the flow of urine from the ....Development of an electrode for stimulation of a transplanted neosphincter. This project aims to develop a novel electrode as an integral component of a new treatment for severe stress urinary incontinence. Treatments for severe stress urinary incontinence are associated with complications and are not completely effective. The new electrode is designed to be activated by an implanted stimulator to control an innervated smooth muscle graft (the neosphincter) to regulate the flow of urine from the bladder. Project research into the design of the electrode will focus on providing safe, effective and efficient stimulation of the neosphincter, while ensuring minimal damage to the surrounding tissues and affording straightforward implantation at surgery.Read moreRead less
Determination of cellular mechanisms underpinning cancer cell metastasis through integrated in vivo imaging approaches. Understanding key steps that drive the spread of cancer is critical to improve current treatment strategies. Using cutting-edge imaging technology and in vivo model systems that mimic the disease, this project will pinpoint key events that are susceptible to drug intervention and identify new therapeutic targets.
Development of an electrode assembly for the stimulation of a transplanted innervated smooth muscle sphincter. This project will design and assess a number of different electrode designs for use in a medical device being developed for the treatment of severe stress urinary incontinence. The project will identify an optimal electrode design, which will be used in future clinical trials of the device.
Single molecule intracellular intravital imaging of actin dynamics. The project intends to develop imaging technology to visualise fundamental processes in cells within a living animal. The focus will be on the actin cytoskeleton, a dynamic macromolecular machine involved in key cellular processes including cell structure, mobility and division. It is exquisitely sensitive to environmental perturbations, requiring it to be studied in cells in living tissue. The project aims to extend the resolut ....Single molecule intracellular intravital imaging of actin dynamics. The project intends to develop imaging technology to visualise fundamental processes in cells within a living animal. The focus will be on the actin cytoskeleton, a dynamic macromolecular machine involved in key cellular processes including cell structure, mobility and division. It is exquisitely sensitive to environmental perturbations, requiring it to be studied in cells in living tissue. The project aims to extend the resolution of live imaging to the single molecule to understand the dynamics of actin assembly with implications for cellular processes that are hijacked in diseases. It also aims to provide a novel assay that may enable testing of the impact of drugs on cellular processes in real time.Read moreRead less
