Characterisation of bone and bone marrow resident tissue macrophages. This project aims to elucidate the identities of tissue macrophages involved in bone and blood system (bone marrow) homeostasis and function, and the molecular signatures underpinning their functional specialisation. It will then investigate whether decline in the function of these specialised macrophages occurs during skeletal and blood system ageing. Both skeletal and blood system decline contribute to age-associated loss of ....Characterisation of bone and bone marrow resident tissue macrophages. This project aims to elucidate the identities of tissue macrophages involved in bone and blood system (bone marrow) homeostasis and function, and the molecular signatures underpinning their functional specialisation. It will then investigate whether decline in the function of these specialised macrophages occurs during skeletal and blood system ageing. Both skeletal and blood system decline contribute to age-associated loss of productivity, and paralleled decline in the resident macrophages in these organs may be a common ageing mechanism. Demonstration that altered macrophage biology unpins decline in blood and bone may prolong peak health and increase productivity in the ageing population.Read moreRead less
Physiological activation and targets of calcium signaling in muscle. The skeletal muscle fibre is a highly specialised cell for the rapid delivery of calcium to elicit contraction, required for posture, movement and thus one's independence. Calcium is also a signal for other purposes, such as triggering other processes within the muscle for its own maintenance. These calcium signals are poorly understood. This project aims to determine when the calcium signals are turned on during normal muscle ....Physiological activation and targets of calcium signaling in muscle. The skeletal muscle fibre is a highly specialised cell for the rapid delivery of calcium to elicit contraction, required for posture, movement and thus one's independence. Calcium is also a signal for other purposes, such as triggering other processes within the muscle for its own maintenance. These calcium signals are poorly understood. This project aims to determine when the calcium signals are turned on during normal muscle activity and what the end result of the signals is for the muscle.Read moreRead less
How appetite-suppressing brain cells maintain normal function and prevent the development of obesity. The brain plays a critical role in body weight gain by balancing appetite-inducing and appetite-suppressing signals. An imbalance in this process causes obesity and promotes diabetes. The aim of this research is to identify how appetite-suppressing brain cells maintain normal function and prevent the development of obesity.
Understanding the determinants of age-related muscle wasting in females . This project aims to investigate the fundamental mechanisms underlying age-related muscle wasting in females. Females live longer than males and are more susceptible to the consequences of muscle ageing. Yet, our current knowledge is overwhelmingly inferred from findings from male cohorts. By comprehensively mapping the functional, molecular and epigenetic mechanisms of ageing in female muscle, this project will generate n ....Understanding the determinants of age-related muscle wasting in females . This project aims to investigate the fundamental mechanisms underlying age-related muscle wasting in females. Females live longer than males and are more susceptible to the consequences of muscle ageing. Yet, our current knowledge is overwhelmingly inferred from findings from male cohorts. By comprehensively mapping the functional, molecular and epigenetic mechanisms of ageing in female muscle, this project will generate new, fundamental knowledge that will allow a unique interpretation of previous research through a sex-specific lens. This knowledge will contribute to better inform sex-specific models of research and practice in the future, ultimately delivering economic and social benefits for Australia and international communities.Read moreRead less
Decoding the rules of fate, attraction and cell migration in perciform fish. This project will interrogate primordial germ cell migration to reveal new insights into the molecular basis of cell migration and chemosensory communication. Key residues needed for ligand-receptor binding and environmental impacts on migration will be investigated with valuable implications in reproductive developmental biology and applied science.
