Virologie und Immunologie

Virology and Immunology

Herpesviruses cause lifelong infections in humans and animals and are controlled by the immune system. Serious disease occurs predominantly in immunologically immature or immunosupressed hosts. Cytomegalovirus (CMV) is an opportunistic pathogen that causes mild infections in healthy individuals, but can cause life-threatening disease in immunocompromised patients (e.g., solid organ or bone marrow transplant recipients). The virus can also be transmitted from mother to child during pregancy and is a leading infectious cause of birth defects.

We study the interaction of herpesviruses (CMV, KSHV) with the host’s immune system. The first line of defense is activated when the virus enters the cell. Specific cellular sensors recognize the invading pathogen and trigger antiviral defenses in order to inhibit virus replication and spread. Viruses, on the other hand, have evolved the capability to counteract these innate antiviral defenses. We analyze how cytomegaloviruses block cellular defense mechanisms and which of the over 160 viral proteins are involved in this process. We also investigate the molecular mechanisms underlying the cytomegalovirus species specificity and cell tropism.
