Compared with those of standard OD490 versus cell number curves generated for each cell type. The percentage survival was calculated using the formula :Epithelial monolayer integrity the effect of the plant lectins on their ability to maintain an intact epithelium was determined by measuring transepithelial resistance (TER). HEC-1A cells were grown as a tight polarized monolayer on a permeable sup
Er. Cells were incubated for 1 h at 37 . HIV-1 transcytosis was assessed by detecting the presence of p24 antigen (HIV-1 core profile ELISA) in the basolateral chamber of the transwell. The inhibition of transcytosis was expressed as the percentage of p24 antigen recovered in the basolateral chamber in the presence of each plant lectin by comparison to that recovered without the plant lectins.

Or media alone were added in duplicate wells, and the TER was measured at 30 min and 2, 4, 9, and 24 h. The epithelial resistance was expressed as follows :epithelial resistance = (/cm2) - the resistance of transwells without cells.HIV cell-free particles transcytosis the epithelial cell line HEC-1A was grown as a tight polarized monolayer on a permeable support of 0.4- -porediameter polycarbonate

Glycans (GAG) heparan sulfates, we assessed the role of plant lectins on the attachment of X4-tropic viruses, known to interact very efficiently with heparan sulfate [11] and data not shown]. Thus, cells were incubated with HIV-1NDK (Fig. 2B) in the presence or absence of different concentrations of HHA and GNA. As depicted in Figure 2B, none of the plant lectins, whatever the concentration, inhib
