This project investigates how brain cells use their molecular machinery to communicate with one another. At the heart of this process lies the synapses, the contact points that connect brain cells. This project will employ an innovative combination of quantitative microscopy techniques, gene knockout mouse models, and advanced computational and mathematical analyses to generate new knowledge on how a crucial set of proteins organises in space and time to regulate synaptic connectivity. This will provide significant benefits, including molecular-level insight into the inner workings of the brain and interdisciplinary training for students. The expected outcomes include a deeper understanding of brain functions, such as learning and memory.Read moreRead less
Tuning the activating stimulus of voltage-gated sodium channels. This proposal aims to advance fundamental knowledge about how proteins (ion channels) found on the surface of neurons (brain cells and nerves) function as molecular conduits of cell-to-cell electrical communication. We aim to study how molecular probes and structural parts of these proteins affect the local chemical environment of ion channels, and how this leads to fine tuning of the ion channel's sensitivity to the stimulus that ....Tuning the activating stimulus of voltage-gated sodium channels. This proposal aims to advance fundamental knowledge about how proteins (ion channels) found on the surface of neurons (brain cells and nerves) function as molecular conduits of cell-to-cell electrical communication. We aim to study how molecular probes and structural parts of these proteins affect the local chemical environment of ion channels, and how this leads to fine tuning of the ion channel's sensitivity to the stimulus that activates them (cell membrane voltage).
The conceptual knowledge gained from this project would advance our understanding of a fundamental physiological process and facilitate the development of drugs that regulate ion channel function, such as anti-epileptics, analgesics and insecticides.Read moreRead less

Summary
How blood vessel stiffness regulates their growth and maintenance. This project aims to reveal an unidentified molecular mechanism of how endothelial cells in the walls of blood vessels detect stiffness of the surrounding environment in order to regulate blood vessel growth and maintenance. The results are expected to advance the emerging field of mechanobiology by combining cutting-edge cell biology and microscopy techniques carried out in novel 3D cell culture and unique quail models. The bene ....How blood vessel stiffness regulates their growth and maintenance. This project aims to reveal an unidentified molecular mechanism of how endothelial cells in the walls of blood vessels detect stiffness of the surrounding environment in order to regulate blood vessel growth and maintenance. The results are expected to advance the emerging field of mechanobiology by combining cutting-edge cell biology and microscopy techniques carried out in novel 3D cell culture and unique quail models. The benefits of these outcomes include generation of knowledge on the impact of tissue stiffness on the signalling mechanisms that drive formation and maintenance of blood vessels. In the long term, this fundamental understanding could give rise to major developments in emerging industries such as organ bioengineering.Read moreRead less
Mitochondria as sensors of environmental threats. This project aims to understand how energy-generating mitochondria control immune responses, both in immune cells called macrophages and in the nematode Caenorhabditis elegans (a free-living roundworm used as a model organism to study gene function and evolutionary biology). The project expects to advance knowledge of how a process called mitochondrial fission enables cells to respond to environmental threats. Expected outcomes include important ....Mitochondria as sensors of environmental threats.

The project expects to advance knowledge of how a process called mitochondrial fission enables cells to respond to environmental threats. Expected outcomes include important conceptual advances in cell biology and genetics, new international and national collaborations, and improved methods for cell biology research. Anticipated benefits include a knowledge base that can be indirectly applied in the long term in the development of new strategies to combat infections.Read moreRead less
Pyroptotic macrophages posthumously sculpt immune responses. The life of an organism relies on the timely birth and death of its cells. Importantly, it is crucial for cells to die not only at the right time, but also in an appropriate manner. This proposal investigates a cell death pathway that triggers potent immune responses. This proposal seeks to reveal precisely how cell death sculpts immune responses. Expected outcomes include new insights into how immune cells die, and how they instruct i ....Pyroptotic macrophages posthumously sculpt immune responses. The life of an organism relies on the timely birth and death of its cells. Importantly, it is crucial for cells to die not only at the right time, but also in an appropriate manner. This proposal investigates a cell death pathway that triggers potent immune responses. This proposal seeks to reveal precisely how cell death sculpts immune responses. Expected outcomes include new insights into how immune cells die, and how they instruct immune responses from beyond the grave. Project benefits include a fundamental understanding of how cell death signalling sculpts tissue immune responses, and knowledge of how to manipulate cell death responses for future basic research and commercial applications beyond this project.Read moreRead less
