Plant lectins. The HIV-1J-RCSF strain was used in this experiment due to the low transcytosis ability of HIV-1Ba-L strain [8]. As shown in Figure 3A, HHA inhibited transcytosis of cell-free HIV-1 in a dose-dependent manner. Similarly to mannan (100 /ml) that inhibited HIV transcytosis up to 41 , increasing concentrations of HHA (range 1-10-100 /ml) afforded a 17 , 42 and 54 decrease of HIV-1JR

Bit Ability ofepithelial cells attachment of HIV-1 cell-free parAbility of lectins to inhibit attachment of HIV-1 cell-free particles on epithelial cells. HEC-1A cells were co-incubated with non-toxic concentrations of each lectins or mannan (100 /ml) and 5 ng of HIV-1Ba-L (A) or HIV-1NDK (B) virus were added for 1 h. Incubation with mannan was used as control. The quantity of attached virus was

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
