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
S) and cells were lysed (1 Triton X-100 for 45 min at 37 ). Cell lysates were harvested and centrifuged at 1,800 rpm for 5 min. The amount of HIV-p24 antigen associated to cell lysates was determined using the HIV-1 p24 core profile ELISA.

Tration of the study plant lectins in epithelial cell (A). MDM)line (HEC-1A) and primary immune cells (MDDC (A). Non-toxic concentration of the study plant lectins in epithelial cell line (HEC-1A) and primary immune cells (MDDC and MDM). HEC-1A and primary immune cells were cultured with concentrations of products for 24 h. After washing, culture viability was determined by using the MTT-cytotoxic
Nan (100 /ml) for 3 h at 37 in a 5 CO2 atmosphere. Cells were washed four times and autologous stimulated T cells were added onto HIV-exposed MDDC at a DC:T-cell ratio of 1:5. Each sample was performed in triplicate. Culture supernatants were harvested every 3 days and fresh medium was added. Supernatants were inactivated with 1 Triton X-100 and frozen at -20 . The viral production by T lympho
Achment on HEC-1A Considering that both HHA and GNA were non-toxic in the epithelial cell system, we further investigated the inhibition of HIV adsorption on the apical side of HEC-1A by the compounds. Cells were thus incubated with HIV-1Ba-L in the presence or absence of different concentrations of HHA or GNA. As depicted in Figure 2A, HHA faintly decreased the attachment of HIV-1Ba-L on epitheli
