Summary
There are fetal sex differences in pregnancy outcomes that place boys at greater risk than girls. These are likely caused by genetic differences in the placenta. We will use 21st century gene sequencing technology to obtain the complete sequence of placental genes in early pregnancy and normal term placenta to determine what the genetic differences are between male and female placentas. This may be important in developing future sex specific therapeutics for babies in the neonatal nursery.
Obesity ensues when calorie intake exceeds energy expended. Hitherto, up-regulating energy expenditure is a relatively unexplored avenue. This project will address 3 facets of energy expenditure (fat, muscle and neural control). Understanding how sex and steroids act in concert to regulate energy expenditure will pave the way towards developing novel anti-obesity agents. This work will delineate mechanisms that underpin gender differences in the regulation of body weight.

Summary
Women are at increased risk of developing fear-related anxiety disorders. We have recently discovered that there sex-specific regulatory mechanisms in the brain that are associated with differences in the control of fear. In this proposal, we will determine whether novel DNA modifications in the female brain are responsible for establishing sex differences in brain states that make the brain more or less responsive to fear-related learning.

Summary
We propose using linked routine Big Data from the NSW health system to investigate sex differences in medications prescribed following a first MI, including deviances from guideline recommendations. We will also quantify differences between women and men in subsequent adverse outcomes, such as recurrent MI, according to treatment prescribed, and will study variations in sex dif

Summary
Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks. Using laboratory animals, we have developed significant new insights into mechanisms regulating egg quality. These insights have allowed us to develop a new approach to infertility treatment - crucially, one that eliminates the need for ovarian hormone therapy used in IVF. This project will investigate the basic mechanisms underlying our new approach to enable safe clinical ....Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks.

Analysis Of Antigen Receptor Sharing By T And B Lymphocytes

Summary
To survive an infection the immune system must rapidly expand the number of immune cells that have pathogen-specific receptors that recognise, and therefore specifically combat, the infection. This normally occurs through proliferation of the immune cells. We have found that in addition to proliferation, the number of cells with these receptors can be increased by a process of receptor transfer between cells. This grant aims to further advance our understanding of this novel phenomenon.
SRY: A Risk Factor For Parkinson’s Disease In Men?

Summary
Parkinson’s disease is a debilitating neurological disorder that affects over 70,000 Australians. This project will test the novel concept that the male sex-determination gene SRY is a risk factor for Parkinson’s disease in men. A potential implication of the work is that it will help explain why men are more susceptible to Parkinson’s disease than women, and may also provide avenues for the development of novel therapeutics for this condition.
