A healthy immune system clears microbes without damaging the body. For this purpose, immune cells are regulated by inhibitory receptors that serve as a break on activation. It is possible to intervene with these receptors: blocking these receptors (thus removing the breaks) led to clinical improvement in the treatment of e.g. melanoma. Vise versa, agonists for inhibitory receptors have potential to suppress excessive inflammation, e.g. in autoimmunity.
The exact mechanism of how inhibitory receptors interact with their ligands is not understood. Especially for soluble ligands that are not expression on cells, it is unknown what receptor:ligand dynamics lead to optimal receptor activation. In this project, funded by the ZonMW Open Competition, immunologists team up with chemists to visualize and follow individual ligand:receptors interactions on immune cells using single-molecule microscopy. This way, we aim to unveil the fundamental requirements of ligands such that we make chemical designer ligands for inhibitory receptors.
For this project, we are recruiting two PhD students; one with a more cellular focus in the UMCU (for details see the "the department" section) and one with a more chemical focus in the Molecular Immunology group headed Sander van Kasteren at Leiden University (Information below). You will actively collaborate with the Leiden-PhD student, and will frequently visit Leiden University. Both PhD students perform work in both laboratories in both institutes. If you are interested (too) in the vacancy at Leiden University, please visit
their website and apply there (too). We are explicitly open to non-Dutch applicants.
About the molecular immunology groupThe molecular immunology group in Leiden works on developing new methods and technology to understand how immune cells interact with their environment; both during activation and deactivation. We use combinations of biotechnology, chemical synthesis, proteomics and single cell techniques to address questions that we cannot currently answer. This workflow means that the projects in the group are highly cross-disciplinary and that a PhD candidate will learn a wide range of cutting edge techniques.
