" The project will aim at deciphering the molecular mechanisms of coronavirus endocytosis. Although Covid-19 and SARS are known to bind to ACE2 receptor at the surface of various epithelial cells, little is known about the molecular details of the endocytic mechanism of these viruses. One of our hypotheses is that the Spike protein of beta-coronaviruses are able to interact with glycosylated molecules at cell surface (lipids, proteins), induce a clustering mechanism and deformation of cell membrane for endocytosis. This mechanism could be similar to the previously described endocytic mechanism of other lectins (mammalian galectins, bacterial lectins such as Shiga toxin,...), as Spike proteins often contain a galectin-fold. The project has three objectives: 1°) Explore the ability of Covid-19 and other beta-coronaviruses to bind sugars; 2°) Explore the ability of coronaviruses' Spike proteins to induce receptor clustering at the host cell surface and endocytic...
