To maintain a proper function of the central nervous system (CNS), the blood-brain barrier (BBB) and the blood-retinal barrier (BRB) are required to be intact to prevent disturbances of the carefully composed environment for these sensitive organs. These physiologically analogous barriers are formed by a continuous, non-fenestrated endothelial monolayer with a highly restrictive excretion of molecules.
Most attention has been paid to the importance of tight junctions, but recent developments have highlighted the regulation of transcytosis as a fundamental factor in barrier integrity. Endothelial transcytosis is usually a caveolae-dependent process that combines receptor-mediated endocytosis, vesicle trafficking via actin cytoskeletal remodeling, vesicle fusion and exocytosis.
In the present project, you will investigate the proteins involved in transcytosis in more detail, using specific pathway inhibitors, mass spectrometry and other molecular techniques. To more specifically track the endocytosis and exocytosis of tracers, you will use confocal imaging and total internal reflection fluorescence (TIRF) microscopy in real-time in living cells. Barrier integrity will be monitored with a CellZscope system.

The Ocular Angiogenesis group, headed by Prof. Reinier Schlingemann and Dr. Ingeborg Klaassen, is part of the Department of Ophthalmology and housed in the Department of Medical Biology. Within our team you work closely together with other PhD students from our own group and collaborative groups. Within the Amsterdam UMC, we have several collaborations with other researches within the field of vascular research, cancer research and neurosciences. Furthermore, we collaborate with numerous national and international groups.
In our department the latest technical advances in imaging, such as high-resolution confocal imaging, correlative electron microscopy and live-cell imaging are available.
