Dittmer Lab

Area of Research

Despite intensive research worldwide, it has not yet been possible to develop vaccines against human pathogenic retroviruses such as HTLV and HIV. The classic methods of vaccine development against viruses have so far largely failed with retroviruses. Therefore, new approaches must be identified in order to be able to successfully produce vaccines against retroviruses. We use a mouse model, the infection of mice with the "Friend Murine Leukemia Virus" (FV), to elucidate the basic immunological mechanisms of vaccination protection against retroviruses. In addition, we are investigating which mediators of the immune system are important for controlling chronic retrovirus infections. The findings from these studies will be used to develop new immunotherapies and vaccines against HIV.
