Funding Amount
$584,390.00
Summary
Age related changes have been shown to impact on the overall functional properties of the intestinal epithelium, which affects overall nutrition and quality of life in the aged population. This proposal will study the cellular and molecular mechanisms underlying intestine deterioration during aging.
Signalling To Telomeres: Mechanisms Of Action Of TGFb

Summary
Cell lifespan is controlled by the enzyme called telomerase. High telomerase activity makes cell immortal as seen in cancer. We recently show that high telomerase activity can be inhibited by transforming growth factor b (TGFb). This may partly explain why TGFb inhibits cancer and induces cell ageing. This project furthers our investigation into the mechanism(s) by which TGFb inhibits telomerase. We recently noted for the first time that TGFb binds to telomerase gene directly, and this is contro ....Cell lifespan is controlled by the enzyme called telomerase. High telomerase activity makes cell immortal as seen in cancer. We recently show that high telomerase activity can be inhibited by transforming growth factor b (TGFb). This may partly explain why TGFb inhibits cancer and induces cell ageing. This project furthers our investigation into the mechanism(s) by which TGFb inhibits telomerase. We recently noted for the first time that TGFb binds to telomerase gene directly, and this is controlled by another protein called c-myc. This work will determine how telomerase is controlled by a balance between TGFb and c-myc in order to find ways to control telomerase and therefore cancer. We will use a combination of sophisticated techniques of cell molecular biology and biochemistry to pinpoint and target different molecules implicated in the actions of TGFb. This study will serve as an important baseline for more applied research in controlling ageing and cancer from development.Read moreRead less
Real Time Visualisation Of T Cell Cycling During Influenza Immune Responses

Summary
Influenza remains a major health threat, particularly in the elderly population. Here we will unravel the mechanisms underlying the expansion of killer T cells, a crucial part of the anti-influenza immune response. Using intravital multi-photon microscopy, we will follow the cell cycle dynamics of individual T cells in real time during different stages of influenza. We will further elucidate how ageing impacts on T cell proliferation. Together, this will provide insight into the mechanisms of an ....Influenza remains a major health threat, particularly in the elderly population.

Using intravital multi-photon microscopy, we will follow the cell cycle dynamics of individual T cells in real time during different stages of influenza. We will further elucidate how ageing impacts on T cell proliferation. Together, this will provide insight into the mechanisms of anti-viral immunity and immuno-senescence.Read moreRead less
Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old musc ....Modulating the molecular and cellular physiology of ageing skeletal muscle. Understanding the underlying mechanisms of how ageing affects muscle is of increasing importance to the community as the number of older persons in the population continues to escalate and the age of retirement increases. Old muscles are slower and weaker than young muscles, and are more easily injured. This proposal is focussed on developing safe therapies to prevent or reverse these age-related effects. Making old muscles young again, is a research strategy that will promote healthy ageing and enable older Australians to enjoy a better quality of life.Read moreRead less
Energy Supply In Glaucoma: One Cell's Trash Is Another Cell's Treasure
Funder

Funding Amount
$122,712.00
Summary
Glaucoma is a leading cause of blindness and affects 65 million people worldwide, yet its underlying cause is not well understood. The work described in this research aims to understand the role of oligodendrocytes in provision of energy to retinal ganglion cell axons, and whether impaired energy supply in retinal ganglion cell axons and the optic nerve will lead to glaucoma. It is expected to provide new insight into glaucoma and potentially lead to new treatments.
RELapses PrevENTion In Chronic Autoimmune Disease: Common Mechanisms And Co-morbidities (RELENT)
Funder
National Health and Medical Research Council
Funding Amount
$499,837.00
Summary
Treatment of people with chronic autoimmune and inflammatory diseases is not optimal, as we do not know how intensively to treat people, and current treatments often have significant side effects. The RELENT program aims, using multiple approaches, to gain a deeper and more useful knowledge of why these diseases are occuring, what might indicate that disease requires more treatment, and which treatments will be most targeted and have the fewest side effects.
