Cellular glycosylation is a highly dynamic process that alters upon activation, inflammation, and oncogenic transformation. Considering that 98% of all cell surface molecules are glycosylated, these glycans encompass an enormous amount of information. Within the immune system, the glycan blue prints are decoded by specific glycan-receptors, such as the C-type lectin receptors or the Siglecs. Lectins act as signaling receptors and are thus able to shape immune responses. We study how the interaction between lectin receptors and their cancer-associated glycan ligands, such as Tn antigen and the elevated levels of Sialic acids and Lewis antigens, orchestrates immune evasion during cancer progression.
