Mechanisms Underlying Increased Cardiac And Renal Noradrenaline Spillover During Heart Failure

Summary
Heart failure is associated with increased release of the neurotransmitter noradrenaline from sympathetic nerves to the heart and the kidney. The raised levels of this neurotransmitter in the heart and the kidney are harmful and lead to reduced survival in heart failure patients. This project will increase our understanding of the mechanisms that control noradrenaline release and may lead to better treatment paradigms to target the detrimental increase in release in heart failure.
Factor XII Dependent Coagulation, Thrombin And Platelet Glycoprotein 1ba In Arterial Thrombosis And Bleeding Disorders

Summary
Clot formation is the key event underlying heart attacks and strokes. There is new data that Factor XII (FXII) can play an important role in clot formation-thrombosis. We aim to examine the role FXII plays in clot formation, in particular the role of FXII in thrombin generation, which is the central event of clot formation, and its interaction with platelet glycoprotein 1ba (another important molecule in thrombosis). New insights into clotting and new therapies can result from our research.
Role Of The Medial Amygdala In Developing Neurogenic Hypertension

Funding Amount
$302,123.00
Summary
We aim to investigate the underlying mechanisms and pathways that regulate the activity of neurons located in the medial amgydala during stress that contribute long term to the development of hypertension. This study is highly relevant to people who inappropriately respond to typical daily stressors and we aim to provide direction for developing specific therapies to interrupt the adverse cardiovascular consequences of chronic stress.
Network Interactions Between Cardiovascular Control Neurons In The Brainstem Underlie Sympathetic Tone

Summary
High blood pressure is a very significant risk factor for many common cardiovascular diseases. Blood pressure is normally tightly regulated by groups of neurons in the brainstem; although we know that this part of the brain becomes dysfunctional in patients with high blood pressure, we do not understand why. We have recently discovered that cardiovascular control neurons can influence each other. The project will determine the effect of such communication in the control of blood pressure.
Synovial Macrophages And T-cells Are Therapeutic Targets In Osteoarthritis

Funding Amount

Summary
Osteoarthritis (OA) is the most widespread musculoskeletal disease in Australia and there are currently no therapies that halt disease progression. Specific inflammatory events play a pivotal role in initiating and driving OA progression. In this study we will define the specific inflammatory cells involved in OA, how and why they change with time, and which can be targeted to stop disease onset and development. This will provide the platform for initiating human clinical trials.
