Research interests

Our main research focus is to understand the mechanisms of protective immunity against human-pathogenic viruses. We study the virus-specific immune responses with a special emphasis on the fine-specificities of CD4 T helper cells that recognize epitopes in the viral structural proteins and thus can provide direct help to B cells producing neutralizing and protective antibodies. Based on the known crystallographic structures of viral proteins, immunodominant regions of T cell epitopes have been mapped to specific structural domains in the context of human infections as well as vaccination with different flavivirus vaccines. The results will provide insights into incompletely understood aspects of human T cell responses that contribute to protective immunity against emerging virus pathogens.

Techniques, methods & infrastructure

CD4 T cell epitope mapping, analyses of immunodominant epitopes in the context of the three-dimensional structures of virus proteins, class II allele-specific affinity predictions and informatics-based approaches as well as in vitro T cell activation assays using structurally defined antigen preparations.
