Summary
Candida albicans is an important opportunistic pathogen, that is widely represented in general medical and dental practice, as well as in the hospital environment. Clinical observations indicate that defects in innate immunity predispose patients to disseminated infection, whereas a weakened cell-mediated immune response is commonly associated with chronic oral infections. Animal models of both chronic and acute oral candidiasis have been developed and characterised by the applicants, and these ....Candida albicans is an important opportunistic pathogen, that is widely represented in general medical and dental practice, as well as in the hospital environment. Clinical observations indicate that defects in innate immunity predispose patients to disseminated infection, whereas a weakened cell-mediated immune response is commonly associated with chronic oral infections. Animal models of both chronic and acute oral candidiasis have been developed and characterised by the applicants, and these have clearly implicated T cells in the process of recovery from primary infection. The models will now be used to analyse the effector mechanisms that lead to clearance of the yeast from the oral cavity, with a particular focus on the role of phagocytic cells, and their interaction with T cells. The acute model will be used to identify immunological variables that can act as markers of protection, and the effectiveness of therapeutic manipulations will be evaluated in the chronic model, with the ultimate aim of developing a protective vaccine for human infections.Read moreRead less
Molecular Diagnosis And Therapy Of Autoimmune Disease Using Translational And Reverse Translational Approaches

Summary
We plan to translate our recent discoveries on human gene variants and molecules produced by immune cells (follicular T cells) into effective therapies for autoimmune diseases. This will involve understanding the mechanisms by which the genes and molecules regulate immune tolerance, stratifying patients with autoimmune disease using newly identified biomarkers, trialling existing biologicals according to affected molecular pathway, and taking novel targets through to commercialisation.
I am an immunologist determining the development and function of the dendritic cell system, including its role in autoimmunity and resistance to infection.
When Prometheus Needs A Hand – How Human Amnion Epithelial Cells Resolve Fibrosis And Regenerate The Liver

Summary
Cirrhosis can progress to end stage disease for which transplantation provides the only hope for survival. Liver donors in Australia are scarce; the need for donor organs is increasing. Using stem cells to repair and regenerate damaged liver may provide an alternative to organ transplantation. We are studying placental stem cells that can decrease inflammation and increase progenitor cells to repair and regenerate liver. Our goal is to use these stem cells as treatment for human liver disease
