AMBER Postdoctoral Fellowship: Cross-scale imaging of the invasion and progression of Toxoplasma gondii in human cells

EMBL is Europe's life sciences laboratory – an intergovernmental organisation with more than 110 independent research groups and service teams covering the spectrum of molecular biology. It operates across six sites in Heidelberg (headquarters), Barcelona, Cambridge, Grenoble, Hamburg and Rome. Our mission is to perform basic research in molecular biology; train scientists, students and visitors at all levels; offer vital services to scientists in the public and private sectors within the member states; develop new instruments and methods; and engage actively in technology transfer.

This postdoctoral position is part of the EU cofund research project AMBER, Advanced Multiscale Biological imaging using European Research infrastructures, will address scientific and sectoral gaps in biological imaging ranging from molecular, through cellular, to tissue, organ and organism levels of organisation, and is coordinated by LINXS Institute of advanced Neutron and X-ray Science. AMBER is funded by the EU Marie Skłodowska-Curie (MSCA) COFUND scheme.

Your work may include clinical and biomedical projects. It may also include technique development work aimed at combining imaging techniques and data analysis to provide a more integrated picture of life processes in the context of health and disease. To be a postdoc fellow at the AMBER programme you will get unprecedented medical, biological, and methodological capabilities, with a profound potential impact for Europe's next generation of research and researchers. When you have completed the AMBER programme you will be extraordinarily well equipped to further your career in academia, at infrastructures, in the health and MedTech sectors, and beyond

Your role 

Toxoplasma belongs to the phylum Apicomplexa, which includes numerous important human and animal pathogens such as Plasmodium species, Cryptosporidium, and Neospora caninum. The protozoan parasite T. gondii is the etiologic agent of toxoplasmosis, a usually mild disease in immunocompetent humans that can turn into a major threat to the unborn and to immunocompromised people, with acquired immunodeficiency syndrome or under chemo- and graft rejection therapies. Toxoplasma is an obligate parasite that develops and proliferates inside a surrogate host cell.

We propose to perform a mesoscale exploration of the invasion and persistence of T. gondii in its host cell. This will be performed for the first time on the same sample using a support that we are developing that is compatible with light, X-ray and electron imaging. We aim to routinely collect X-ray tomographic data on whole infected human cells in order to target regions of interest (e.g interface between parasite and host cell organelles) for FIB milling and cryoET data collection. Phase contrast tomography of these samples is already providing unprecedented insight into the infection process, correlation with high resolution tomography on targeted regions will be a sea change in Toxoplasma research and will potentially allow molecular details of infection to be determined via sub-tomogram averaging of complexes in regions previously identified by phase contrast imaging. This project poses unique challenges in correlating 3D volumes at different scales and resolutions. In collaboration with the Hakimi lab (IAB, Grenoble), beamline ID16A at the ESRF and the EMBL imaging centre in Heidelberg, we are developing the tools required for this project and are starting to generate the first data sets. This is an opportunity to drive innovative developments in data processing in correlative imaging applied to an important infectious agent.

You have
