Professor Ralf Dressel MD PhD
Research Group Leader
Department of Cellular and Molecular Immunology
University of Göttingen
Ralf Dressel completed his MD thesis in 1997 in the Division of Immunogenetics at the University of Göttingen. He has worked as a Research Group Leader in the Department of Cellular and Molecular Immunology, Göttingen since 2005. Since 2007 he has worked as a Consultant Immunologist (DGfI) and he was appointed as Professor in 2009.
The Research Group of Professor Dressel works in the fields of tumour immunology, transplantation immunology and more recently autoimmunity. The function and role of cytotoxic cells, i.e. cytotoxic T lymphocytes and natural killer cells, is in the centre of our interest. We are studying the major histocompatibility complex (MHC) and especially MHC-linked genes that control the function of cytotoxic cells. To explore the medical relevance of these topics we are analysing genetic risks of Graft versus Host Disease (GvHD) after haematopoietic stem cell transplantation and polymorphisms affecting the outcome of experimental cancer immunotherapy. The discovery of new pluripotent stem cell types including induced pluripotent stem cells (iPSCs) has improved the perspectives of using stem cells to obtain cells and tissues that can be transplanted to treat a variety of degenerative diseases including heart failure and Parkinson's disease. We have started to determine the immunogenicity and tumorigenicity of pluripotent stem cells, progenitor cells, and differentiated cells and their susceptibility to immunological cytotoxicity. Moreover, we are studying the contribution of autoimmune reactions to the development of heart failure after increased mechanical load. Prof Dressel is PI within the “Deutsches Zentrum für Herz- Kreislaufforschung e.V. (DZHK)“.
The current projects are funded by the DFG (GRK1034, SFB 1002), BMBF (DZHK), and the EU (Marie Curie Initial Training Network).
Professor Dressel is regularly involved in the teaching programs for Immunology and Human Genetics provided for medical students as well as for biology students at the University of Göttingen. In addition, he is actively teaching in a BSc/MSc/PhD program on Molecular Medicine. He is scientific member of the Göttingen ‘Graduate College Pharmaco Genomics', ( http://www.gcpg.de/).

Pranali Shah (India) Early Stage Researcher.
Pranali procured her Bachelors' degree in Biotechnology, in 2011. She has technical expertise in immunohistochemistry, western blotting, biochemical assays, polymerase chain reaction and ELISA. In 2012, Pranali completed a Masters Degree in Infection and Immunity, from University College London, with a dissertation thesis titled, “Investigating antigen dominance in serum antibody response in mice, to nasopharyngeal colonization”. She also is co-author of a paper published in Vaccine journal- http://dx.doi.org/10.1016/j.vaccine.2013.03.013.
