Summary
We have designed a vaccine based on a unique delivery system. Mice immunised with vaccine were protected from a tumour challenge. We will now design a vacine with a cancer associated protein so that people once immunised can make killer cells. Since humans have different genetic makeup we will produce a vacine which is more effective and will benefit everyone. This vaccine will be more effective than a current vacine in that has yielded promising results in humans.
Development Of An Assay To Distinguish Between Recent And Established HIV-1 Infection

Summary
We have discovered a marker of recent HIV infection. Further refinement of this assay and fully evaluating it on samples from individuals infected with different subtypes of the virus will result in an HIV incidence assay ready for commercialisation. An assay capable of distinguishing between recently acquired and established HIV infection would be most valuable in establishing the incidence of infection for epidemiological surveys, to clearly identify new infections following vaccine trials and ....We have discovered a marker of recent HIV infection.

Modulating Immune Responses By Targeting Dendritic Cells Using Dendritic Cell Specific Markers.

Summary
The ability to modulate immune responses would have major health benefits. Dendritic cells (DC) are key regulators of the immune system. Different types of DC possess different cell surface molecules and have differing regulatory functions. We have identified four novel DC surface molecules that can be used to target different types of DC. We aim to use antibodies against these molecules to either enhance the effectiveness of vaccines or to suppress autoimmune diseases.
Despite recent advances in therapeutic options, chronic viral infections, including infection with hepatitis C virus and hepatitis B virus, continue to be a significant cause of morbidity and mortality in Australia and affecting hundreds of millions of people worldwide. This R&D program aims to develop a cheaper drug formulation that is easier to deliver and more stable for transport to remote areas.
Cellular And Molecular Mechanisms Of Transcutaneous Immunisation

Summary
Vaccines are among the most effective medical interventions. The recent discovery that cholera toxin, when applied to the normal skin of humans and laboratory animals, stimulates powerful and protective immune responses to itself, and to other proteins has opened up the possibility of needle-free vaccines in the form of skin patches. How CT brings about this effect is currently unknown. We have discovered that the immune stimulating effect of CT depends upon the production of an immune protein ( ....Vaccines are among the most effective medical interventions. The recent discovery that cholera toxin, when applied to the normal skin of humans and laboratory animals, stimulates powerful and protective immune responses to itself, and to other proteins has opened up the possibility of needle-free vaccines in the form of skin patches. How CT brings about this effect is currently unknown. We have discovered that the immune stimulating effect of CT depends upon the production of an immune protein (cytokine) called tumour necrosis factor (TNF). TNF is known to activate specialised immune cells within the skin (Langerhan's Cells ) and we hypothesise that the interaction beween CT and LC via TNF is the pathway to the potent immune response. In this project we propose to investigate the cells and molecules involved in the immune effects of CT in the skin with a view to the development of new skin based vaccine strategies.Read moreRead less
