Summary
Papillomavirus (PV) is a sexually-transmitted virus that is a major cause of cervical cancer. Our study will determine how PV is able to form new virus particles inside infected cells. This is a critical part of the virus life-cycle, and a better understanding of this process may allow it to be trageted by anti-viral treatments. In addition, we will develop a method to create non-harmful virus particles which we will use to study human immune responses to the virus.

Summary
Vaccines to prevent cervical cancer are currently being developed. These will be used to prevent infection with the causal virus, papillomavirus. However, there are very many people world wide who already have papillomavirus infection, which could turn into cancer at any point over the next 30 years. Therefore, there is a need for a vaccine that could be given along with the preventative vaccine, which would treat existing infections. This study addresses the characteristics of the immune respon ....Vaccines to prevent cervical cancer are currently being developed.

Therefore, there is a need for a vaccine that could be given along with the preventative vaccine, which would treat existing infections. This study addresses the characteristics of the immune response required to treat existing papillomavirus infections, since this is not currently known.Read moreRead less

Summary
This project will determine whether immunisation can be used to effectively treat an existing infection. To date, immunisation has only been used to prevent infection, but there are many chronic infections where intervention might help the body's defences to to a better job and clear the chronic infection. In this study, we will work out whether this approach can be applied to a virus infection ( papillomavirus) which is associated with cancer.

To date, immunisation has only been used to prevent infection, but there are many chronic infections where intervention might help the body's defences to to a better job and clear the chronic infection. In this study, we will work out whether this approach can be applied to a virus infection ( papillomavirus) which is associated with cancer. We will test immunisation against a chronic and lifethreatening disorder in which warts grow in the respirarory tract, as there is currently no satisfactory treatment for this. If the project is successful we may also learn which blood tests are likely to predict the outcome of immunisation to treat infection.Read moreRead less
Delineation Of Receptor-activated Conformational Signalling Pathways In HIV-1 Envelope Glycoproteins

Summary
Although antiretroviral therapy has prolonged the life of people infected with HIV, the virus rapidly develops resistance. Therefore it is essential to develop new antiviral agents to combat HIV infection. The first stages of infection include the process of the virus attaching to cellular receptors and the fusion of viral and cellular membranes leading to entry. In this project we seek to understand how the surface proteins of the virus mediate viral entry and identify new antiviral targets.
Hepatitis C virus (HCV) and Human immunodeficiency virus (HIV) infect 200 million and 50 million people world-wide, respectively, and there are no preventative vaccines. The work outlined in this fellowship seeks to understand the structure and function of the major surface proteins of these viruses, their ability to be recognised by the immune system and to develop a novel vaccine for the prevention of HCV.

Summary
Respiratory Syncytial Virus (RSV) is the most important viral cause of respiratory tract disease in both infants and the elderly. However, there are few available options for control, whether by vaccination or therapeutic intervention. This proposal investigates the way RSV infects cells. A clearer understanding of the molecular basis of this process should provide potential targets for new drugs that can block this process and new insights for the generation of vaccine candidates.

Summary
Killer T cells are white blood cells that are key for helping control virus infections and in the recognition and elimination of cells that have become cancerous. This proposal aims to identify novel molecular mechanisms that control the ability of killer T cells to mediate their antiviral and anti-cancer functions. This will provide molecular targets for possible clinical interventions designed to either promote immunity (vaccination) or limit damage caused by T cell responses that target self
