RESEARCH ACTIVITIES

γδ T cells are unconventional T cells that express a γδ T cell receptor (TCR) on their cell surface instead of an αβ TCR as on conventional αβ T cells. γδ T cells can have several roles, including protection against infections and tumors. The general approach of our current research is to obtain insight into human γδ T cells by applying sophisticated molecular biological techniques on clinical samples. Important in vivo findings are then further investigated in vitro in order to understand molecular mechanisms. A main focus of our research is the role and ontogeny of human γδ T cells in early life. This research is leading to novel targets (molecules, cells) for pharmacotherapy.
