Summary
IgG antibodies are a crucial component of the immune system, and significantly contribute to host protection against cancer and infectious diseases. Additionally, therapeutic IgG antibodies have been developed for treatment of cancer and inflammatory diseases. The studies proposed herein will elucidate one important aspect of how IgG antibodies act as anti-inflammatory agents, and may lead to the design of more effective IgG based therapies for the treatment of inflammatory diseases or cancer.

Summary
As of June 2020, COVID-19 has infected over 7.3 million people and killed over 413,000 in the six months since it emerged. It has pushed many healthcare systems and economies to breaking point. We recently discovered that a known drug is effective at stopping the virus under laboratory conditions. This research will determine exactly how the drug works, evaluate it's potential in pre-clinical models, and re-optimise the drug's antiviral properties to ensure that we can prevent future pandemics.
Phosphorylation Of Synaptic Vesicle Glycoprotein 2 (SV2) Regulates Endocytosis Of Synaptotagmin For Synaptic Transmission

Summary
Antiepileptic drugs typically target ion transporters or neurotransmitter receptors. Synaptic vesicle glycoprotein 2 (SV2) is a rare example of a synaptic vesicle recycling protein that is the target of an antiepileptic drug. It also binds botulinum and tetanus neurotoxins. We discovered SV2 contains activity-dependent signalling molecules. Charactersation of these molecules and will allow a deeper understanding of the molecular basis for its role in epilepsy and toxin action.
The Role Of Protein Glycosylation In The Malaria Parasite

Summary
The parasites that cause malaria have unique proteins on their surface that are essential for infection of humans. These proteins are useful for making vaccines to train our immune system to recognize and block infection by the malaria parasite. Our latest research has shown that these proteins are modified with sugars that enhance parasite virulence. We are studying these modifications more closely to facilitate the development of improved malaria vaccines.
