The host-specific cytomegaloviruses (CMV) are large DNA viruses of the beta herpesvirus family which remains after acute infection in a state of replicative latency in host tissues for life. The establishment of latency is the result of a long period of co-evolution between CMV and its host. During this, the virus and host have developed a fine balance of immune evasion and immune control to maintain latency. Under conditions of immunosuppression, productive infection can reoccur by reactivation of latent genomes. Primary infection or reactivation can lead to life-threatening diseases, e.g. interstitial pneumonia in immunocompromised patients after hematopoietic cell transplantation (HCT). The main research topic of our group is to study the establishment of acute and latent CMV infection in a mouse model. We aim to understand the molecular and immunological basis of CMV control by the immune system and the viral countermeasures that lead to the establishment of latency.
