Defining the molecular and cellular mechanisms of beta cell dysfunction. This project will investigate the influence of environment in the functional adaptation and maladaptation of pancreatic beta cells in diabetes. The research will define the molecular and cellular mechanisms linking environmental triggers such as obesity, high fatty acid levels and hyperglycaemia to beta cell dedifferentiation and dysfunction.
Gene therapy for islet transplantation. Improved understanding of aetiology of type I diabetes. Development of islet transplantation as a clinical therapeutic for type I diabetes.

Reduced burden on health system for management of diabetic complications for subjects with type I diabetes
Endocrine signalling from bone cells in the regulation of glucose and energy homeostasis. Osteoporosis, obesity and diabetes are increasingly common, all of which are in urgent need of more effective therapies. This project examines powerful neuropeptide signalling pathways that integrate bone homeostasis with whole body energy and glucose balance. Initial studies have defined the efferent hypothalamic pathways of this system and this project will build upon these findings to examine the feedbac ....Endocrine signalling from bone cells in the regulation of glucose and energy homeostasis. Osteoporosis, obesity and diabetes are increasingly common, all of which are in urgent need of more effective therapies. This project examines powerful neuropeptide signalling pathways that integrate bone homeostasis with whole body energy and glucose balance. Initial studies have defined the efferent hypothalamic pathways of this system and this project will build upon these findings to examine the feedback signals produced by bone cells to regulate adipose and pancreatic function. Exploring this entirely new paradigm of skeletal biology, will reveal novel circulating factors capable of regulating adipose and glucose economies, as well as bone mass, thereby offering potential therapies for these debilitating conditions.Read moreRead less
Masterminding Reproduction: Kisspeptin and RFamide-Related Peptide. There are a number of concerning trends in reproductive health. Women are reporting difficulty conceiving and maintaining pregnancies; while sperm count and quality are declining in men. More concerning is the increase in reproductive cancers. Gonadotropin-releasing hormone (GnRH) antagonist and agonist have been used for decades to treat reproductive cancers (such as breast cancer and prostate cancer), infertility and precociou ....Masterminding Reproduction: Kisspeptin and RFamide-Related Peptide. There are a number of concerning trends in reproductive health. Women are reporting difficulty conceiving and maintaining pregnancies; while sperm count and quality are declining in men. More concerning is the increase in reproductive cancers. Gonadotropin-releasing hormone (GnRH) antagonist and agonist have been used for decades to treat reproductive cancers (such as breast cancer and prostate cancer), infertility and precocious puberty. Kisspeptin and RF-related peptide may offer more physiological alternatives to GnRH, without detrimental side effects. We will fully explore these two newly defined and major players in reproduction and provide a physiological framework for their progression to clinical use.Read moreRead less
Understanding and regulating autoimmune disease through the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) family transcription factor, v-rel reticuloendotheliosis viral oncogene homolog B (RelB). This program is well-aligned with the national research priority: Promoting and Maintaining Good Health. The disabling conditions rheumatoid arthritis and type 1 diabetes affect over 1% of Australia's population.

This program is well-aligned with the national research priority: Promoting and Maintaining Good Health. The disabling conditions rheumatoid arthritis and type 1 diabetes affect over 1% of Australia's population. They are incurable, so disability and the need for treatment persist into old age and life expectancy is reduced. The program focuses on more effective and safer treatment, and future disease prevention, with immune therapy. This will have social and economic benefits to Australia. The research will advance Australia's intellectual leadership in Immunology, providing research training and career opportunities, and will lead to strong collaborations between basic scientists, clinicians and industry.Read moreRead less
RNA-based analysis for prediction of islet death in diabetes. Death of insulin-producing cells is a common feature in diabetes. Presently, a blood glucose test remains the only blunt instrument to diagnose diabetes. The RNA-based analysis for prediction of islet death in diabetes (RAPID) study links with eight clinical trials to test this newly developed non-invasive assay for predicting diabetes. Early diagnosis will help to reduce diabetic complications in later life.
