Summary
Our genes encode proteins that perform the tasks of life. Most proteins are chemically modified after they are made to control how, when, and where they function. Prof Hogg discovered a new chemical modification of proteins that is important in health and disease. He will apply this discovery to develop new diagnostics and therapies for heart attacks and stroke. Prof Hogg is one of the few Australians to take new diagnostics and therapies developed in the lab to evaluation in patients.
Defining Targets And Establishing Methods For Prevention, Diagnosis And Therapy Of Inflammation, Atherosclerosis And Thrombosis

Summary
My research focuses on preventing and treating atherosclerotic disease and its complications such as heart attack and stroke. This will be achieved by developing new imaging technologies, with the aim to detect unstable atherosclerotic plaques, as well as innovative new drugs preventing inflammation and thrombosis as the major contributors of heart attack and stroke.
The mechanisms regulating expression and function of surface receptors on blood platelets are critical for understanding cardiovascular diseases involving aberrant platelet function, not only thrombotic diseases such as heart attack or stroke, but other pathology involving platelets including coagulopathy and autoimmune thrombocytopenia caused by anti-platelet antibodies. Improved diagnosis and therapeutic targeting of platelet-specific receptors mediating arterial thrombosis can save many lives ....The mechanisms regulating expression and function of surface receptors on blood platelets are critical for understanding cardiovascular diseases involving aberrant platelet function, not only thrombotic diseases such as heart attack or stroke, but other pathology involving platelets including coagulopathy and autoimmune thrombocytopenia caused by anti-platelet antibodies. Improved diagnosis and therapeutic targeting of platelet-specific receptors mediating arterial thrombosis can save many lives given the prevalence and severity of disease.Read moreRead less
Investigating A Potential New Treatment For Stroke

Summary
Blood clots blocking blood flow to the brain (stroke) are a major cause of death and disability. Safety concerns limit approved therapies to a small subset of patients, highlighting an urgent need for safer, more effective drugs. Our studies show that inhibitors of the enzyme PI3Kbeta increase blood clot permeability, increasing clot ‘dissolvability’, without increased bleeding. This raises the possibility that PI3Kbeta inhibitors may represent a safe and effective adjuvant therapy for stroke.
The Ghost In The Machine: Understanding How Haemostasis Is Regulated By Allosteric Disulphide Bonds

Summary
Genes encode proteins, which are the machinery of life. All life forms make proteins that contain bonds between pairs of cysteine amino acids called disulphide bonds. Prof Hogg has discovered a type of disulphide bond, the allosteric disulphide, which controls how proteins work by breaking or forming in a precise way. His research aim is to define how haemostasis is controlled by allosteric disulphides. Haemostasis gone wrong leads to heart attack and stroke.
