Understanding T cell responses.
The Gerlach lab studies immune responses mediated by T cells, in particular CD8 T cells.
CD8 T cells play a crucial role in providing protection against many infections and cancers, but may also contribute to immunopathology in conditions of continuous antigen presence. In recent years it has become clear that T cells are an extremely diverse group of immune cells, and that different T cell subsets have different properties.
T cell subsets differ with respect to their expression of cell surface receptors, their production of inflammatory and cytotoxic mediators, their anatomic localization, and their migratory behavior. As a consequence, not all CD8 T cell subsets play an equal role in the control of infections and tumors, or the pathology associated with inflammatory disorders. What we find particularly interesting is that such diversity exists even among CD8 T cells that recognize the exact same antigen. Using a combination of several state-of-the-art single-cell technologies and experimental model systems, we study how different CD8 T cell subsets arise, what their relationship is, and what mechanisms underlie their specific properties. We hope that this knowledge will contribute to improved vaccines and immunotherapies.

Our lab is actively involved in research education at Karolinska Institutet in the field of immunology. This includes organization of the PhD course ‘Basic Immunology’, teaching on various aspects of T cell immunology and immunological techniques within PhD courses, the Biomedicine Master and Medicine program, as well as research supervision of PhD students.
If you are excited about Immunology, have a look at the most recent program of the Karolinska Immunology Seminar Series (https://news.ki.se/karolinska-immunology-seminar-series-kiss).
