The position will be held in the Molecular Biophysics group in the Medical Faculty at Lund University, in close collaboration with CureVac in Germany. The development of mRNA LNPs has intensified in the past years, particularly fueled by the SARS-CoV-2 pandemic. Beyond the treatment of COVID-19, LNP technology enables gene editing, protein replacement therapy and therapeutic cancer vaccines. Nonetheless, there are numerous challenges associated with the formulation, delivery, and efficacy of mRNA-LNPs to date. Despite the various advancements in the field, many aspects of the structure-activity relationships in LNPs still remain to be elucidated. CureVac, a biotechnology company based in Tübingen, Germany (https://www.curevac.com/en/), has been a pioneer in the field of mRNA research for the past 24 years. The successful delivery of mRNA in vivo is contingent on the LNP delivery vehicle. This project aims to delve into the lipid-based building blocks which make up the LNP, utilizing powerful structural tools to investigate structure-activity relationships that will enable the future efficient design of potent mRNA LNP therapeutics. CureVac has been focusing on innovations in the lipid space for the design and in vitro/in vivo characterization of novel LNPs and the identification of factors that can significantly improve potency following intravenous administration. The project will make extensive use of synchrotron X-ray facilities such as MAX IV, ESRF, Diamond, and neutron beam facilities such as ILL, ISIS (as well as the ESS spallation neutron source which will become available during the period of the project). Data from these facilities will be used with information from cryo-EM to establish reliable structural models associated with different types of LNPs and their variation in response to different conditions. Where appropriate, isotope labelling will be exploited to enhance the visibility of different LNP components. The project aims to use machine learning trends to deliver reliable prediction methods for LNP morphology and content. To apply for this position, see https://www.ambercofund.eu/for-applicants.
