About me

Professor at Karolinska Institutet. Director of Doctoral Studies and Head of International Affairs at Department of Dental Medicine.

Margaret Sällberg Chen received her D.D.S. and Ph.D. degrees from Karolinska Institutet. Following postdoctoral training at The Scripps Research Institute, La Jolla, USA, where she developed T cell receptor transgene models for immunological studies of chronic viral infection, she was recruited to the former Swedish Institute for Infectious Disease Control to study immunology and experimental vaccines. She became full professor in clinical oral immunology in 2020 at KI. She has published over 65 scientific articles and cited > 2500 times, she has active commitments on numerous scientific and editorial board. 

Research description

The lab is broadly interested in immunological mechanisms effective in eliminating microbial pathogens associated with chronic diseases and tumors. The research pursues several lines investigating cellular functions capable of sensing and killing intracellular pathogens and tumors, and the target identification. The models are exclusively human infectious diseases and the methodologies employed include synthetic genetics, genetically modified cells and animals, viral and non-viral vectors, and next generation sequencing.

Major research area: infection and cancer immunity, redirection of lymphocytes, T cell receptors, viral and neo-antigens, human microbiome and immune cell interactions, therapeutic targets in oral diseases including tumors and endodontic infections.
