Figure 6From: Sialylated glycans as receptor and inhibitor of enterovirus 71 infection to DLD-1 intestinal cellsA proposed SA-based "double-edge sword" on blocking and destructioing of EV71 infections. SA (α2,6)-linked galactose can block EV71 infection by competition of sugar receptor, and the galactose can be linked with cationic compounds such as lactoferrin or chitosan for destruction of EV71.Back to article page
