This form of diabetes is a major chronic disease from childhood, as well as accounting for at least 10% of adult-onset diabetes. It occurs when the body�s immune system attacks and destroys the beta cells in the pancreas that make insulin, the hormone that controls the level of glucose in the blood. The team was one of the first in the world, and is the only one in Australia, to develop screening programs to test and identify people at risk for type 1 diabetes. They showed that the underlying disease could start years before symptoms occurred and discovered genes that determine the rate at which the underlying disease progresses. They have also found evidence that the disease may be triggered by gut viruses called rotaviruses in genetically-susceptible individuals. They showed that type 1 diabetes could be prevented in a mouse model by getting the immune system to make a protective response to insulin, and then went on to apply this in at-risk humans in a controlled trial of intranasal insulin, the first of its kind. They have used genetic techniques not only to pinpoint the mechanisms responsible for killing the beta cells but also to modify the beta cells to make them resistant to attack by these mechanisms. The multidisciplinary approach of the team will be directed to further understanding the genetic and environmental factors underlying type 1 diabetes and the immune mechanisms, particularly involving special white blood cells called T cells, that kill beta cells. A molecular target of the immune attack, the parent of insulin called proinsulin, will be used, paradoxically, as a tool to regulate the immune system and avert the attack. This will be achieved by giving proinsulin via the mucosa of the naso-respiratory tract or via the bone marrow-derived stem cells, initiallyin the mouse model as a test of feasibility for human application. In parallel with these approaches to prevention, specially constructed viruses will be used to transfer several new genes into beta cells to improve their resistance to immune attack, so that they can be transplanted into people with established diabetes without the need for potentially toxic drugs that suppress the immune system overall. The integrated research of the team is helping to provide a sound, rational base for the eventual prevention and cure of type 1 diabetes.Read moreRead less

Summary
Preconception and early pregnancy is a critical time for a women's health and that of her future child. New research suggests that a woman's genetic potential, her lifestyle and the physical and socioeconomic environment in which she lives, and her biological and social relationship with her male partner, all impact on the long term health of her baby. Abnormal events around the time of conception and in early pregnancy can predispose a newborn to later occurrence, in adult life, of conditions i ....Preconception and early pregnancy is a critical time for a women's health and that of her future child. New research suggests that a woman's genetic potential, her lifestyle and the physical and socioeconomic environment in which she lives, and her biological and social relationship with her male partner, all impact on the long term health of her baby. Abnormal events around the time of conception and in early pregnancy can predispose a newborn to later occurrence, in adult life, of conditions including heart disease, diabetes, obesity and stroke. These adverse events originate in the way that eggs and sperm develop, the uterus is prepared for implantation, the attachment of the early embryo to the lining of the uterus and subsequent growth of the placenta. This Program will study the early life events that promote or limit development of a baby's true potential for successful and healthy life. A better understanding of how lifestyle and environment interact with genes and biology to facilitate optimal growth of the fetus will underpin new preventative measures and therapeutic treatments for infertility, miscarriage and other reproductive disorders. The knowledge gained will inform health policy and clinical practise to improve reproductive health in all Australian women and promote healthy development in all Australian children. The team of researchers is a world-class group of clinicians, scientists and epidemiologists who have made major contributions to our understanding of this area. This team will interface with clinics and hospitals that engage with women prior to and during pregnancy, while having the influence to alter clinical and health practices as well as public health policies. The team will utilize the latest, most technologically advanced laboratory methods and clinical skills, including gene profiling, imaging of early pregnancy, randomised clinical trials and access to the best epidemiological and statistical assessments.Read moreRead less
