Study Of Papillomavirus DNA Encapsidation And Formation Of Infectious Virions

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.
Regulation Of The Quality Of DNA Repair By Timing In The Cell Cycle

Summary
During responses to infection or immunisation, antibody-producing _B� cells mutate their antibody genes at extreme rates. Rare mutations which improve the antibodies are selected by competition between B cells favouring those which make the best antibodies: Darwinian evolution on extreme _fast-forward�. We aim to understand this process because it is essential for normal immunity and effective vaccination, and because when it goes wrong, it can cause aggressive human cancers.
Development Of DNA Targeted Platinum Agents As Potential Anticancer Drugs

Summary
A number of clinically useful anticancer drugs damage DNA. As a result of this damage these drugs kill cancer cells. This project aims to develop new platinum-containing compounds which are specifically targeted to DNA. Through this strategy it is possible that new and more useful anticancer drugs could emerge.

Summary
This project is based upon the observation that the mammalian immune system can distinguish between its own genetic material (DNA) and the genes of infectious agents such as bacteria. This fact has implications for understanding how the immune system copes with infection, and also for design of new therapies and vaccines. Our central aim is to define exactly how this recognition system works. The cells that respond most vigorously to foreign DNA are large white blood cells called macrophages. We ....This project is based upon the observation that the mammalian immune system can distinguish between its own genetic material (DNA) and the genes of infectious agents such as bacteria. This fact has implications for understanding how the immune system copes with infection, and also for design of new therapies and vaccines. Our central aim is to define exactly how this recognition system works. The cells that respond most vigorously to foreign DNA are large white blood cells called macrophages. We aim to find the macrophage protein which binds to foreign DNA and triggers the activation of the immune system. The type of immune responses initiated by foreign DNA may be useful in treatment of allergies and cancer and for improving vaccinations.Read moreRead less
