By understanding the causes of persistent immune activation and chronic inflammation in HIV patients, we aim to develop prognostic tools and adjunctive therapies to predict and improve health outcomes.
HIV infection is a chronic viral infection which can be managed using combination antiretroviral therapy such that progression to AIDS is greatly minimised. Long term management of patients receiving antiretroviral therapy, especially their risk of non-AIDS co-morbidities, is a major concern.
- To understand the causes of immune activation and inflammation remaining in HIV patients with virologic suppression on antiretroviral drugs
- To understand the mechanism of increased risk of cardiovascular disease in HIV+ patients
- To determine how inflammation alters natural killer cell signaling and function
- To understand the role of monocytes in malaria immunity.
Our group focuses on understanding the immune defects that persist in HIV+ patients receiving combination antiretroviral therapy, and how these contribute to decreased life expectancy and increased non-AIDS co-morbidities such as cardiovascular disease.
By understanding the causes of persistent immune activation and chronic inflammation in HIV patients, we aim to develop prognostic tools and adjunctive therapies to predict and improve health outcomes.
We study cells of the innate immune system (monocytes and natural killer cells) that are important to inflammation.
Highlights from our working group include:
- Demonstration of persistent natural killer cell activation in virologically suppressed HIV patients
- Demonstration that monocyte phenotypic and functional changes in HIV patients mirror those seen during normal, healthy ageing
- Development of an in vitro model to study the differentiation of monocytes into foam cells and their role in atherosclerotic plaque formation
- Determination of signalling pathways required for cytokine responses to chondroitin sulphate binding P. falciparum malaria strains and the effect of HIV infection on these.
