Annual Meeting

Sugar coating is, in fact, important

A 2022 annual meeting session on glycobiology

Like people, whether they want to or not, cells need to interact with others around them. One way people interact is through the way they dress. Indeed, we often are judged by the clothes we wear. Cells are "clothed" in a specialised sugar layer known as the glycocalyx in which specific sugar structures are displayed on proteins and lipids. Based on this outer clothing layer, the cell is recognised by both friend and foe.

In this symposium, we will learn about new ways to identify, locate and quantitate the glycans present on different cells under specific conditions. We also will hear how we can dress cells for success through modification of their surface structures. In another section, we will learn how pathogens can recognize and invade cells through specific glycocalyx structures.

We also will hear several accounts of how cancer progression can be mediated through overexpression of glycans such as sialic acid and heparan. Apparently, as with people, inhibitions can be dampened by exuberance in cellular dressing. Learn about this and more at our symposium.

Keywords: glycosylation, glycocalyx, cellular interfaces, cancer, immunity, infection

Who should attend: anyone who is interested in understanding how cells function and interact with their environment through their surface glycan coat and anyone interested in cool new ways to modulate those interactions through carbohydrate chemistry and enzymology

This session is powered by interdisciplinary science with a sweet touch.
