Immunology and Neuroimmunology

Prof. RNDr. Eva Kontseková, DSc


The Laboratory of Neuroimmunology is focused on the understanding of the mechanisms of the neuro-immune interaction in Alzheimer’s disease neurodegeneration.

To study the interactions between the IMMUNE and the NERVOUS systems affected by the neurodegenerative process, we use transgenic animal models (mice and rats). We develop immunotherapy approaches for monitoring of the impact of aging on the immune system and effectiveness of immunotherapies. Great emphasis is put on the understanding of the molecular underpinnings of the immunotherapy mechanism of action.

The group has a long tradition in the preparation and characterization of monoclonal antibodies against a wide range of proteins. We develop antibodies that recognize the critical antigenic determinants on the pathological forms of tau protein, which is the key player in the pathophysiology of Alzheimer’s disease.

The antibodies also serve as sensitive tools for the study of the structure-function relationship of the intrinsically disordered proteins like tau. The antibodies helped us to uncover a therapeutic target for pathological tau protein.

Finally, we analyze markers of ageing of the immune system and their connection to the ability to respond to new immune stimuli. The laboratory is equipped with complete setup for proteomic and molecular biology analyses and a dedicated facility for cell and tissue culture research. The available high-end flow cytometer Becton Dickinson LSR Fortessa allows us to measure multiple parameters in a single run.
