Gammaherpesviruses are very prevalent among human and animal populations. It is, therefore, essential to understand their biological cycle in order to develop therapeutic and prophylactic strategies to fight them. In the first instance, our aim is to understand how these viruses, which persist throughout their host's life, can be spread in the presence of a specific immune response. To this end, we are examining how these viruses enter the cells of an organism and how they escape recognition by the immune system. Based on this knowledge, we wish to develop strategies that would have the potential to prevent the spread of these viruses within a population. Secondly, we wish to investigate the imprint left by the gamma herpesviruses on the immune system of their hosts. In fact, the influence of past infections is not known in most animal models. However, our immune system is continuously being moulded by environment antigens and infectious agents that it finds in the gamma herpesviruses. Consequently, we wish to investigate the positive and negative effects of these infections on the immune reaction of the host towards the heterologous antigens.
