Summary
Most of our genome is made up noncoding RNA; however, nothing is known about why a special class of noncoding RNA would be expressed in synapses, and how this affects learning and memory related to neuropsychiatric disorders. Understanding the fundamental molecular machinery underlying the formation of fear extinction memory will enable the development of new treatment approaches for anxiety-related disorders that are characterised by memory deficits.
Inflammasome Sensors And Immune Protection Against Tumorigenesis

Summary
Intestinal cancer is a leading cause of death in Australia and worldwide. Defects in the immune system can lead to the development of intestinal cancer. In this project, we will investigate the critical role of an immune sensor in inhibiting the development of intestinal cancer. This project will provide new insights into the interplay between the immune system and cancer biology and will potentially inform the development of new immunotherapies.
Cells recycle old components using a system called the proteasome. Some people are born without parts of the proteasome, and they suffer from a disease associated with inflammation. We have identified the molecular trigger for this inflammation. Our findings are also relevant for patients being treated with proteasome inhibitors. In some of these diseases, such as lupus, inflammation can be a side-effect of proteasome inhibitor therapy, and we can now reduce this and make the treatments safer.
Amyotrophic Lateral Sclerosis (ALS) is a progressively fatal neurodegenerative disease characterized by aggregates of a protein called TDP-43. ALS also features the presence of several inflammatory cytokines in the central nervous system. In this project, we will study how TDP-43 abnormally mislocalizes within cells, releasing mitochondrial DNA and triggering a novel pathway of inflammation. We propose that targeting this pathway could lead to new treatments for ALS.
Manipulating Antibody Production To Maximise Memory In Vaccine Responses

Summary
Our immune system provides protection from germs. The secretion of germ-specific proteins (antibodies) is an integral component of this defence and the basis of virtually all vaccines. Pandemics of Influenza and SARS-CoV-2 and failure to develop vaccines against HIV and Malaria remind us that our strategies need urgent improvement. Increasing our understanding of how our body defends us by specifically targeting foreign structures will reveal avenues for successful, rational vaccine development.
Characterisation And Targeting T Cellular Metabolism To Improve Control Of Chronic Viral Infections

Summary
CD8+ T cells are the frontline warriors of our immune system that can eliminate infected or cancerous cells. However, diseases caused by overwhelming viral infections are associated with widespread impairments in immunity and cellular metabolism. Here, we propose to examine molecular pathways involved in cellular metabolism that could be utilized to improve therapies against viral infection and cancer.
