Wie Impfstoff-gefüllte Fetttröpfchen ihre Fracht entlassen

Wenn die Lipidnanopartikel bei Aufnahme in die Zelle in eine saure Umgebung gelangen, organisieren sie ihre Hülle grundlegend um, zeigt eine Studie der FAU.

Impfstoffe und andere Medikamente werden zum Schutz oft in kleinen Fetttröpfchen verpackt, den sogenannten Lipid-Nanopartikeln. So werden sie von den Zellen aufgenommen und entlassen erst dann ihre Fracht. Um diesen Prozess zu optimieren, haben FAU-Forschende den Vorgang am Computer simuliert. (1/2)

Bottom-up Investigation of Spatiotemporal Glycocalyx Dynamics with Interferometric Scattering Microscopy

Over recent decades, the glycocalyx, an extracellular organelle composed of a multitude of glycolipids, glycoproteins, proteoglycans, and glycoRNA, has gained considerable interest in cellular biology. While research in this field has revealed its tremendous importance in ever more aspects of physiological and pathological cellular processes, many of the principles that govern the role of the glycocalyx in these processes on a molecular level are still unknown. In order to unravel the fundamental laws underlying glycocalyx function, new technologies are required that enable the distinction between individual subprocesses within the intricate environment of the glycocalyx. Here, we establish an experimental platform to investigate the dynamics of the glycocalyx at the nanometer and microsecond length and time scales in a bottom-up fashion. We synthesized defined oligosaccharides and installed them on supported lipid bilayers. This way, synthetic glycolipids were assembled to glycocalyx model systems with tunable properties. By investigating these tunable model systems with interferometric scattering (iSCAT) microscopy, we gain access to the required spatiotemporal resolution. We found a strong correlation between the molecular structure of several investigated model glycans and global dynamics of the system. Our findings are corroborated by atomistic molecular dynamics simulations and coarse-grained Brownian dynamics simulations. Our results provide the first direct experimental evidence on the relationship between glycan structure, organization, and dynamics, offering a robust and versatile basis for a quantitative understanding of glycocalyx biology and physics at the molecular level.
