Project description
Characterising the roles of glycans in viral infection with atomic resolution
Like the fuzz on a peach, all cells are covered with surface glycans. This diverse family of macromolecular sugars is a key target of viruses, many of which adhere to the outer glycan layer to begin the process of infecting a cell. Characterising this process is essential to combatting viral infections, but quite challenging given the tremendous complexity of glycans and their synthesis, chemical structure, conformation and dynamics. The ERC-funded Glyco13Cell project proposes a radical approach. The team will chemically remodel the glycans directly on the cell surface while leveraging isotopic labelling. Then, nuclear magnetic resonance active probes will illuminate the roles of glycans at atomic resolution.
Objective
Every human cell is covered by a dense coat of glycans (sugars, carbohydrates). Sugars are the first molecules that viruses encounter when they approach host cells. Many viruses encode lectins to adhere to the outer glycan layer and start infection. In this scenario, Glycoscience holds a tremendous potential for combating infections. Elucidating the molecular basis of infection is essential, but far from trivial. The complexity of the chemistry of glycans, including synthesis, structure, conformation, and dynamics hampers the full knowledge of sugar-mediated recognition events and the development of glycan-based drugs.
Surfing the current information on glycan/lectin interactions, we stumble in contradictory outcomes, pointing out the tremendous difficulty of translating in vitro results to the in vivo environment, which limits the translation from the bench to clinics.
I propose an unprecedented strategy to untangle the key glycan’s molecular interaction features breaking the limits in answering fundamental questions related to sugar structure, presentation, dynamics, and eventually function. I will chemically remodel the glycans, directly on the cell surface, using NMR active probes to decode their roles at atomic resolution, while preserving their presentation in a near-to-in-vivo environment.
I am in a favoured position to accomplish this project due to my experience in NMR, synthesis, and mammalian cells manipulation. I will combine chemical biology tools, novel chemical and enzymatic synthesis, and NMR-based methods: From chemistry to biology and beyond.
Glyco13Cell will gap down the observed differences between in vitro and in vivo results paving the way for develop novel glycan-based tools for predicting, diagnosing and treating infectious diseases.
Now it’s time. The increasing understanding of infection biology with the atomic precision of modern chemical tools will make glycomics run in parallel with genomics & proteoms towards personalized medicine.
