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
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.

Of plant lectins on HIV-1 transcytosis through a tight epithelial cells monolayer To evaluate the capacity of each plant lectin to inhibit in vitro HIV-1 transcytosis through genital epithelial cells, such as HEC-1A cells, we used a dual-chamber model in which the apical chamber consisted of a confluent monolayer of HEC-1A cells, and the basal chamber contained fresh medium. Cell-free virus (HIV-1
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
