Institute of Immunology (IfI)

Laboratory for Comparative Immunology

The Laboratory for Comparative Immunology analyzes basic mechanisms of the immune response against bacterial or viral pathogens in different animal models (rainbow trout, Oncorhynchus mykiss, European bats, Eptesicus spec; and raccoon Pyrocor lutor) with the focus on functions of different leukocyte populations. We establish monoclonal antibodies specific for activation and differentiation markers expressed on leukocytes (so called CD molecules) and develop different functional assays. The transcriptome of different leukocyte populations of bats and raccoon will be analyzed using deep sequencing.

Moreover we develop monoclonal antibodies specific for different viral and cellular antigens for other research projects.
