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

Summary
The early events in immunity require various molecular interactions. We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants. We will ....The early events in immunity require various molecular interactions. We will examine the structural and biophysical basis for some of these interactions, including those associated with transplant rejection and autoimmunity. We will explore the impact of variation in immune response genes on immune evasion and disease susceptibility. Our basic research will determine the mechanisms by which the immune system discriminates between different self and micro-organism associated determinants. We will address the structural and biochemical basis for operation of an immune molecule called tapasin and unravel the basis for how some viruses escape the function of this molecule, thus allowing their immune evasion. We will also explore the use of modified small proteins called peptides in a humanized model of gluten hypersensitivity resembling that of Celiac disease. The molecular basis of the natural human immune system's capacity to recognise and reject grafts will be examined. This complements work aimed at improving the prediction of clinical graft rejection in transplantation. Dendritic cells play a central role in immunity, responsible for capturing material, whether from micro-organisms or self tissues, and presenting it to cells of the immune system. Our program will study the development and immunological function of the different dendritic cell subtypes. We will determine the relative contribution of each to the maintenance of immune tolerance and to the induction of immunity to several pathogens, including herpes simplex virus and malaria. Novel dendritic cell surface molecules that we have discovered will be tested for their ability to enhance the effectiveness of vaccines. Overall, this program utilises a broad array of immunological techniques designed to dissect the development and function of various immune system cell types and determine the structure-function relationships between important cell surface molecules involved in immunity.Read moreRead less
Antibodies are made by B-cells and are essential for a functional immune system. B cells circulate in the body, and, when they encounter an invader, they mature into antibody-producing cells (ASC). A small proportion of the cells become “memory” cells with the potential to become ASC should the same infection occur in the future. This is the basis of vaccination. This program aims to understand how a B cell changes into an ASC. We aim eventually to be able to improve vaccines and understand dise ....Antibodies are made by B-cells and are essential for a functional immune system.

We aim eventually to be able to improve vaccines and understand diseases such as allergy, lupus, arthritis and leukaemia to develop novel therapies.Read moreRead less
