Summary
Cancer cells promote their own growth by exploiting the body’s natural defence. This natural defence is termed inflammation and cancer cells utilise inflammation to grow and metastasise. We have identified two exciting proteins that are required for cancer cells to stay alive. Under conditions that drive inflammation, if we remove these proteins cancer cells now activate their death signals and die. Our discovery provides new opportunities on fundamental ways by which cancer cells can be killed.
The Splanchnic Anti-inflammatory Pathway: The Real Inflammatory Reflex

Summary
The brain strongly influences immune function through a neural reflex: the inflammatory reflex. This reflex was recently revised and a new model for its efferent arm, in stark contrast with the existing version, was proposed: the motor pathway of this reflex is purely sympathetic and travels through the splanchnic nerves. The aim of this project is to define the peripheral and central neural pathway of this reflex. Future improvements in health and medical knowledge will follow

Summary
We have developed a therapy that kills hepatitis B virus infected cells and promotes elimination of infection. We are now testing novel drugs that can be used to maximise the efficacy of our new treatment to promote better outcomes that may be translated to other infections.
Regulation Of TNF Expression In Inflammation And Cancer

Summary
By studying a spontaneous mutation in mice, we have found an error in the TNF gene (a major factor in many inflammatory diseases) that causes severe arthritis, heart valve disease and gut inflammation. We have also identified new regulators of TNF expression, which might be useful therapeutic targets to limit inflammation. We intend to study the role of these regulators in controlling the expression of TNF, and the link between chronic inflammation and the development of cancer.
Differential Changes In Cortical Tumour Necrosis Factor Signalling In Mood Disorders And Schizophrenia

Summary
Changes in inflammation-related pathways contribute to the symptoms of psychiatric disorders and tumour necrosis factor ? (TNF) is a protein central to regulating theses pathways. We have now shown that changes in pathways regulated by TNF are present in the brains of people with schizophrenia and mood disorders. This means that the symptoms experienced by those with the different disorders may be linked to differential changes in TNF-regulated pathways in the brain.
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.
Allosteric Targeting Of The Dopamine D2 Receptor: A Novel Approach For The Treatment Of Parkinson’s Disease And Schizophrenia

Funding Amount
$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.
Mapping The TNF Pathway: A Qualitative And Quantative Molecular Analysis Of The Components And Post-translational Modifications Involved In Physiological And Pathological TNFR1 Signalling

Funding Amount

Summary
TNF is a master regulator of the inflammation response and dysregulated TNF signalling causes many human diseases. We will use a cutting edge mass spectrometry technique that we have developed to analyse molecules required for TNF signalling. Understanding how the TNF signalling works in all cell types and with different forms of ligands will open up therapeutic opportunities to selectively target TNF signalling in inflammatory diseases, such as Rheumatoid Arthritis and Cancer.
The Novel CXCR4/CCR7 Heterodimeric Chemokine Receptor Is A Key Determinant Of Breast Cancer Metastasis.

Funding Amount

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.

Summary
Diseases associated with exaggerated inflammation account for a large toll of human disease. We have recently described how mice with a mutation in the Sharpin gene, that causes the chronic proliferative dermatitis phenotype (cpdm), can be rescued by crossing these mice to TNF (Tumor Necrosis Factor) knock-out mice. Our findings suggest that TNF induced cell death, rather than TNF induced cytokine production, may be at the root of many inflammatory diseases and we aim to test this hypothesis in ....Diseases associated with exaggerated inflammation account for a large toll of human disease.
