Regulated muscle-based thermogenesis for body temperature regulation. Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the skeletal muscles that are closer to the body core contribute the majority of heat, how the muscles of the limbs have their heat generation curtailed as necessary, and how this is coordinated by the body in response to ambient temperature. Project out ....Regulated muscle-based thermogenesis for body temperature regulation. Mammals maintain a constant core body temperature by generating heat in resting muscles in response to changes in the environmental temperatures. This project aims to show how the skeletal muscles that are closer to the body core contribute the majority of heat, how the muscles of the limbs have their heat generation curtailed as necessary, and how this is coordinated by the body in response to ambient temperature. Project outcomes include defining, for the first time, how heat generation in the muscles of the body is regulated. This should provide critical knowledge of mammalian evolution and ways to manipulate metabolism, which may provide ways to assist the production of meat by managing hypothermia and hyperthermia risk in agriculture.Read moreRead less

Molecular control of postnatal heart development. This project aims to improve our understanding of how the heart develops after birth and the molecules that control this process. Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryoni ....Molecular control of postnatal heart development.

Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryonic development but little is known about the molecules that control maturation after birth. This project aims to build new knowledge that is expected to improve our ability to generate mature heart muscle cells for stem cell applications, tissue repair and regeneration.Read moreRead less

Summary
The formation and regulation of ovarian follicular fluid. At ovulation in mammals the egg and its surrounding fluid are released from the ovary, yet we understand very little about how fluid accumulates in the ovary in the first place. This project will for the first time discover how this fluid forms, and what controls its rate of formation.
Deciphering novel control mechanisms in the skin. The overall aim of this project is to understand the cellular mechanisms that maintain skin integrity, and in particular, the role of a novel population of regulatory cells in mediating this process. This is important for our understanding of fundamental physiological interactions in the skin. The proposed research aims to uncover essential new information regarding a recently discovered population of regulatory cells, with particular respect to ....Deciphering novel control mechanisms in the skin. The overall aim of this project is to understand the cellular mechanisms that maintain skin integrity, and in particular, the role of a novel population of regulatory cells in mediating this process. This is important for our understanding of fundamental physiological interactions in the skin. The proposed research aims to uncover essential new information regarding a recently discovered population of regulatory cells, with particular respect to understanding their mechanisms of action. The outcomes of this work should provide fundamental new knowledge of skin physiology and lead to novel insights regarding how skin integrity may be maintained following the disruption of homeostasis mechanisms.Read moreRead less
Deciphering the cellular functions of caveolae that govern lymphatic vascular development. Lymphatic vessels play crucial roles in tissue fluid homeostasis, immunity, and fatty acid transport. Despite our recent understanding of genetic pathways that modulate lymphatic cell fate specification, how cellular changes mediate morphogenesis of the lymphatic tree remains to be elucidated. This study will combine cell biology and developmental genetics approaches using mouse and zebrafish transgenic li ....Deciphering the cellular functions of caveolae that govern lymphatic vascular development. Lymphatic vessels play crucial roles in tissue fluid homeostasis, immunity, and fatty acid transport. Despite our recent understanding of genetic pathways that modulate lymphatic cell fate specification, how cellular changes mediate morphogenesis of the lymphatic tree remains to be elucidated. This study will combine cell biology and developmental genetics approaches using mouse and zebrafish transgenic lines that label lymphatic endothelial cells to investigate the role of caveolae proteins in the construction of the lymphatic vascular network. This project aims to improve our fundamental understanding of the processes that govern vascular system assembly and will broaden basic knowledge of organ morphogenesis. Read moreRead less
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
Sarcoplasmic reticulum-mitochondrial functional interactions in muscle. Muscle in the body of animals and human has the ability to adapt to stress placed on it, to improve performance. This allows new physical tasks that have been unfamiliar to become easier. One form of stress on the muscle is the demand to work longer without fatigue. This can be important for animal survival or athletes training for sport. A single session of intense muscle contractions can lead to the muscle increasing its c ....Sarcoplasmic reticulum-mitochondrial functional interactions in muscle. Muscle in the body of animals and human has the ability to adapt to stress placed on it, to improve performance. This allows new physical tasks that have been unfamiliar to become easier. One form of stress on the muscle is the demand to work longer without fatigue. This can be important for animal survival or athletes training for sport. A single session of intense muscle contractions can lead to the muscle increasing its capacity for endurance within 24 hrs. This project aims to examine this phenomenon in animals and human to decipher the mechanism involved in the beneficial muscle changes experienced in such a brief time. It will provide benefits such as the potential to manipulate human muscle condition and animal muscle (meat) quality.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.
