 Project objective

Our current assays to determine the receptor specificity and vaccine efficiency of influenza A virus fail as they do not represent receptors available in the human upper respiratory tract. The lack of these receptors in our laboratory hosts to create vaccines significantly dampen yields, the resulting mismatched vaccines do not afford proper protection and further drive antigenic drift. The objective of this proposal is to elucidate the functional receptor of human influenza A viruses. By using antigenically drifted viruses, we expect to understand how glycan specificity changes due to immune pressure but it will also lead to the identification of a glycan that is utilized by all human IAV viruses. With this knowledge, better surveillance techniques, culture models and structure-based inhibitors can be developed. Using a novel and sophisticated cell-engineering tool, based on lipidated sugars, we will show functional glycan receptor usage. In addition, I will create cell lines in which human influenza A vaccine viruses grow to high titers without adaptation, thus providing superior protection. To achieve this goal, I propose to enzymatically synthesize complex glycans (AIM 1), including sialic acid modifications that are found on the respiratory tract epithelial cells of humans and other IAV hosts. Several enzymatic methods and glycan array tools are in place, and thus the chance of success is high. I already set-up preliminary methods for the use of lipidated N-glycan structures and extensive knowledge on SEEL is present in the department (AIM 2). For creating super vaccine producing cell lines I will use genetic approaches that previously have shown to be successful (AIM3). The systems dealing with sugars enabling function, either for infection or vaccine research, I term sugar-enable, will provide new endeavors to create glycan-analog inhibitors and will bring us steps closer to better vaccines.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "SUGAR-ENABLE" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email (fabio@fabiodisconzi.com) and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.
