Time resolved studies of complement activation and phagocytosis

Applications are invited for a PhD fellowship/scholarship at Graduate School of Natural Sciences, Aarhus University, Denmark, within the Molecular Biology and Genetics programme. The position is available from August 2025 or later.

Title:
Time resolved studies of complement activation and phagocytosis

Research area and project description:
The complement system is a component of the extracellular innate immune system. Atomic structures have captured stable conformations of large multidomain complement proteins, but no dynamic information is available. The project will fill this gap and offer insight on the actual paths taken in conformational changes and their duration.

As cases, we will analyze two large multidomain complement proteins and their complexes using single molecule FRET (smFRET) spectroscopy. We will integrate this dynamic information with structural information to generate detailed structure & time based mechanistic models for two key effector functions of complement: Activation of the terminal pathway and phagocytosis of complement opsonized cells.
To enable smFRET studies we will develop donor-acceptor reporter systems based on atomic structures using a double approach. First, we will use our unique know-how to establish site-specific incorporation of non-canonical amino acids in complement proteins for fluorophore labeling. Second, we will label a battery of well-characterized complement specific single domain antibodies.

The project builds on a number of unpublished cryo-EM structures. The student will combine cryo-EM , smFRET and functional assays. The student will work in a team with a postdoc and a staff scientist. The smFRET work will be carried out in collaboration with the group of Victoria Birkedal at the iNANO center at Aarhus University located near to the Department of Molecular Biology and Genetics. The project is funded by a grant from the Novo Nordisk Foundation.
