Ch lectin to interact with epithelial cell's receptors, labeled HHA and GNA were incubated with epithelial cells. As depicted in Figure 2C, only HHA but not GNA interacted with receptors expressed at the surface of HEC-1. Moreover, the preincubation of GNA with epithelial cells followed with several washes did not inhibit viral attachment whereas the preincubation of GNA with R5 viral particles in
