The immunology and Infection laboratory studies malaria and leishmaniasis, two important parasitic diseases that affect millions of people around the world every year. Our research focuses on CD4+ T cells because of their central role in controlling anti-parasitic immunity. We use our discoveries to improve immune responses following vaccination or drug treatment with the aim of generating long-lasting immunity in communities to reduce the numbers of infections, and ultimately eliminate these diseases. Our findings relate to inflammation, and as such, our work also has important implications for developing treatments for infections, cancer and autoimmune diseases that impact thousands of Australians.
CURRENT RESEARCH
- Identifying the mechanism of action for a novel inflammatory molecule called NKG7 that can be modulated for clinical advantage in colitis, cancer, malaria and leishmaniasis.
- Developing drugs that can target NKG7 to treat diseases.
- Repurposing a licensed drugs that can be used to block type I interferon signalling in malaria and visceral leishmaniasis and improve anti-parasitic CD4+ T cell responses.
- Discovering how the DNA sensing molecule STING regulates T cell functions in malaria
- Developing strategies to manipulate the metabolism of T cells to prevent the development of tissue pathology without compromising anti-parasitic immunity in malaria and visceral leishmaniasis
