Molecular determinants of congenital HCMV infection

Human cytomegalovirus (HCMV) is one of the nine known human herpesviruses. It causes a particularly high disease burden in congenitally infected newborns, often leading to severe physical or sensorineural defects. One major reason for the success of HCMV in establishing life-long infection is its ability to withstand humoral immunity, particularly neutralizing IgG antibodies. Consequently, there is no vaccine available. Antiviral therapy against HCMV disease is restricted to few antiviral agents fraught with severe side effects including teratogenic damage and emergence of virus resistance. Consequently, they are not applicable in some clinical settings including pregnancy. Therefore, vulnerable patient groups will greatly benefit from alternative intervention strategies with fewer risks.
We are interested in solving the molecular mechanisms driving congenital HCMV infection and aim to identify viral targets for novel intervention and prevention strategies.
