Teunis Geijtenbeek is a molecular immunologist with expertise in viral infections. He studies molecular and cellular mechanisms that are important for the induction of innate and adaptive immunity against life-threatening pathogens, including HIV-1, Mycobacterium tuberculosis and fungi. Geijtenbeek's research has revealed that HIV hijacks the immune system to infect the host. In particular he is interested in host-pathogen interactions and the underlying molecular mechanisms in order to develop new strategies in the fight against HIV infection. His research is also relevant to allergies and inflammatory diseases, as similar mechanisms play a part in their development. The fundamental research will be applied to translational research with the ultimate goal of providing new therapies.
Geijtenbeek works as leader of the Host Defense research group at the AMC Center for Experimental and Molecular Medicine (CEMM). He previously worked at the Radboud University Nijmegen Medical Centre and the VU University Medical Center in Amsterdam. Geijtenbeek has published extensively in professional journals, such as Cell, Nature Immunology, Nature Medicine, Immunity, PNAS and the Journal of Clinical Investigation. In February 2010 he was awarded the prestigious Vici grant from the Netherlands Organisation for Scientific Research (NWO) for his research entitled ‘Gatekeepers fight against HIV' (Poortwachters strijden tegen hiv).
