Summary
Molecular pharmacology is the study of how hormones, neurotransmitters and pharmaceuticals interact with our cells through receptors, which transfer a signal across the cell membrane to change the function of that cell. Chemokine receptors are recognised to play a role in the development of many cancers. Understanding how these receptors work has enormous implications for improving our ability to develop better anti-cancer treatments with fewer side effects.
Allosteric Targeting Of The Dopamine D2 Receptor: A Novel Approach For The Treatment Of Parkinson’s Disease And Schizophrenia

$469,644.00
Summary
The dopamine D2 receptor is a brain protein that is the target for drugs that are used in the treatment of schizophrenia and Parkinson's disease (PD). In both cases the current drugs have significant side effects because they simply act to switch the receptor off or on respectively. We will focus on a new class of drugs that, because they act to tune up or tune down the activity of the D2 receptor, may be a safer more effective approach to treat these disorders.
The Novel CXCR4/CCR7 Heterodimeric Chemokine Receptor Is A Key Determinant Of Breast Cancer Metastasis.

Summary
Novel cellular receptor has been identified that works as a switch to turn on cellular functions that are responsible for the metastatic dissemination of cancer cell to distant organs. The make-up and regulatory mechanisms of this novel receptor will be studied together with its potential utility as the marker of metastatic breast cancer.
Characterisation Of The Adiponectin Receptors - AdipoR1 And AdipoR2

Summary
The increasing incidence of cardiometabolic disease highlights an unmet need for novel therapeutic approaches. Greater understanding of the detail governing cardiometabolic function is required to provide a foundation to construct effective strategies. We will characterise 2 novel receptors that are important in the regulation and maintenance of cardiometabolic systems, seeking to identify strategies to enhance receptor, improve cardiometabolic function and reduce disease burden.
Understanding Allosteric Modulation And Biased Signalling At Family B GPCRs

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.
This research will push the boundaries of current knowledge in receptor pharmacology and translate this knowledge into clinical outcomes. Receptors are proteins on the surface of our cells that bind hormones, neurotransmitters and pharmaceuticals. By better understanding the complexities of how these receptors work at the molecular level, the objective is to develop improved treatments and better clinical management for a range of medical conditions.
The Structural Basis For Biased Agonism At The Glucagon-like Peptide-1 Receptor

Summary
The glucagon-like peptide-1 receptor plays an essential role in nutrient-regulated insulin release, and is a major target for therapeutic treatment of type 2 diabetes. The binding of different drugs to this receptor can promote distinct signalling profiles inside the cell that can lead to different physiological outcomes. Understanding the mechanistic basis for this will provide a framework to enable rational design of novel, better and safer therapeutics for the treatment of diabetes.
Understanding The Structural Basis For Family B G Protein-coupled Receptor Function

Funding Amount
$745,082.00
Summary
G protein-coupled receptors (GPCRs) are the largest family of cell surface proteins that enable communication from external signals to the inside of cells of the body. Family B GPCRs are a therapeutically important subclass of these receptors and they play crucial roles in bone and energy homeostasis, cardiovascular control and immune response. This grant will uncover fundamental knowledge on how these receptors work, and will enhance future development of therapeutics.
How Do P75 And Sortilin Facilitate TrkA-mediated Survival Signalling?

Funding Amount

Summary
Neurotrophins are the classical growth factors that regulate neuronal survival and death throughout the nervous system in both the developing and adult animal. These factors signal through one of three receptors, but precisely how the receptors interact to propagate cell survival is unclear. The goal of this grant is to unravel the molecular basis underpinning this life and death signalling decision so that we can then devise ways to promote cell survival in neurodegenerative conditions
