Summary
HIV-AIDS is still one of the leading causes of infectious human fatality worldwide. The genome of HIV encodes six viral accessory proteins that are necessary for viral replication and infection. One of these genes, viral infectivity factor (vif), is essential for production of infectious virus. Exactly how this viral protein works within the cell is not clear at present. Current literature suggests that Vif acts in some way to enhance reverse transcription, one of the early stages of the viral l ....HIV-AIDS is still one of the leading causes of infectious human fatality worldwide. The genome of HIV encodes six viral accessory proteins that are necessary for viral replication and infection. One of these genes, viral infectivity factor (vif), is essential for production of infectious virus. Exactly how this viral protein works within the cell is not clear at present. Current literature suggests that Vif acts in some way to enhance reverse transcription, one of the early stages of the viral life cycle. We aim to investigate the action of Vif in stabilizing early HIV reverse transcription complexes to understand how it acts to enhance HIV replication and viral infection. The early stages of HIV replication are critical for establishing infection and hence ideal targets for therapeutic intervention. This research will help understand how Vif works in a cell and affects the infectivity of HIV viral particles and may be suggestive of potential targets for development of anti-viral drugs.Read moreRead less

Summary
Bone marrow transplantation (BMT) is the most effect treatment for a number of conditions, especially leukemia. Graft versus host disease (GVHD) is a complication of BMT and results in the death of up to 50% of transplant recipients. GVHD occurs when the newly transplanted immune system recognizes the recipient as foreign and mounts and immune reponse against the patients tissues. These studies will focus on identifying and understanding the function of the immune cells which drive GVHD.

While therapies to treat cancer have continued to improve one area that, in theory at least, shows great promise in the treatment of tumours is manipulating the immune system to effectively recognize and destroy cancerous lesions. Experiments in human and animal systems have clearly shown that the immune system has the potential to respond to tumour cells and trials of tumour vaccines are underway. It has recently become apparent that the immune responses to tumours may be inhibited by classes of regulatory immune cells. Eliminating these cells results in a more vigorous and effective anti-tumour response. This project will seek to discover the mechanisms of action of theses regulatory immune cells in order to devise more effective anti-cancer vaccines and therapies.Read moreRead less
