Brief description Varicella zoster virus (VZV) is a herpesvirus which infects up to 90% of the population. VZV causes two skin diseases: chicken pox (varicella) predominantly in childhood and shingles (herpes zoster) in middle to old age people. Whilst VZV usually causes relatively mild disease in healthy individuals, VZV still causes significant morbidity in children and adults. VZV causes life-threatening disease in immunocompromised individuals such as patients who are elderly or have HIV disease. Shingles affects many elderly individuals and a major complication is prolonged severe pain or post-herpetic neuralgia (PHN), which can be severely debilitating and often requires follow-up medical care for months or even years after the initial attack. Despite its significant impact on the community, little is known about how this virus functions and causes disease. This project aims to improve our understanding of how VZV infection of the skin affects the function of specialised skin cells in order to provide novel information for the development of therapies aimed at lessening the impact of VZV disease on the community. This project has three main components: (1) To determine what the differences are in the types of immune cells present in infected skin from chicken pox and shingles sufferers. (2) To assess the impact of VZV infection on the ability of specialised immune cells (called dendritic cells) to function properly (3) To identify which parts of the virus (called genes) code for functions that interfere with the proper function of specialised immune cells (dendritic cells)
