Summary
Family B GPCRs are therapeutic targets for drugs treating osteoporosis, hypercalcaemia, Paget’s disease, type II diabetes and are being actively pursued for other diseases that represent major global health burdens. Despite huge financial input, there are no orally available drugs that act on these receptors. This speaks to a lack of mechanistic understanding of how they work. My research focuses on addressing this question and how to exploit these receptors to design and identify better drugs.
Control Of TGF-beta Superfamily Signalling In Human Disease

Summary
Members of the transforming growth factor ? (TGF-?) family of proteins play crucial roles in adult tissue homeostasis. In recent years a new paradigm has emerged suggesting that inhibition of TGF-? signalling could be an effective strategy for restoring homeostasis in disease-affected tissues. Dr Harrison’s overall research strategy is based on this concept, and is particularly focussed on developing specific antagonists of individual TGF-? proteins.
Structural And Mechanical Determinants Of Airway Hyperresponsiveness

Summary
In asthma and chronic obstructive pulmonary disease, the capacity for airway passages to narrow is increased which limits airflow in and out of the lung and contributes to disease severity. The aim of this project is to identify the underlying physiological abnormalities producing the increased narrowing capacity. The investigations will focus on the role of the airway smooth muscle and epithelial layers that are widely implicated in driving the increased narrowing response, but for which the ev ....In asthma and chronic obstructive pulmonary disease, the capacity for airway passages to narrow is increased which limits airflow in and out of the lung and contributes to disease severity. The aim of this project is to identify the underlying physiological abnormalities producing the increased narrowing capacity. The investigations will focus on the role of the airway smooth muscle and epithelial layers that are widely implicated in driving the increased narrowing response, but for which the evidence remains circumstantial.Read moreRead less
The Molecular Mechanism Of Ion-coupled Transport In The Brain

Summary
Cells in the brain communicate through chemical signals called neurotransmitters. Neurotransmitter transporters reside in the membranes of cells and are responsible for regulating levels of these chemicals in the brain. They play an important role in the normal function of the human brain but their dysfunction is responsible for many diseases including Alzheimer's disease and motor neuron disease. It is crucial to understand how these proteins work in both normal and disease states.
Peripheral Membrane Proteins In Health And Disease

Funding Amount
$469,151.00
Summary
Peripheral membrane proteins are critical for processes such as cell transport, signaling, neurosecretion and development. As such, their dysfunction can lead to many debilitating diseases including cancer, inflammation and neurodegeneration. This project will establish fundamental new knowledge about how peripheral membrane proteins regulate cell function, how their perturbation or mutation results in human disease, and will inform efforts to target them for future therapeutic outcomes.
A Targeted Nutrient-depletion Approach To Tackle Prostate Cancer

Summary
Prostate cancer is the most prevalent male specific cancer, and has a similar incidence to breast cancer in women. We are studying the role of protein pumps that control the amount of nutrients taken into and out of cancer cells. We are aiming to structurally determine LAT1 and LAT3, two nutrient pumps important for cancer progression, and to use these structures as a platform for drug design where the intention is to drugs 'starve’ the cancer by restricting nutrient uptake.
