Sence of serial dilutions of the plant lectins. Plant lectin concentrations that gave culture viabilities of more than 80 compared to control cultures were considered to be non-toxic (Fig. 4A). (ii) Efficacy of lectins against attachment of HIV-1 on MDDC Intraepithelial and submucosal dendritic cells (DCs) and CD4+ T lymphocytes are the predominant cell populations firstly targeted by HIV-1 [13].
Vities in the epithelial cell line HEC-1A (i) Toxicity Any topical microbicide approved for human use first need to be evaluated for epithelial toxicity, because of the direct contact between the product and the vaginal mucosal surface. Thus, non-toxic concentrations of the plant lectins were determined by culturing the epithelial cell line, HEC-1A, for 24 h in the presence of different lectin con

Us combinations of plasmids. Bar, 10 m. In the absence of a viral RNA, MS2-YFP had the appearance shown in Fig. 4A to C. (A) pFIVgag-CFP, pMS2-YFP, and pFIV -24. The nuclear envelope region (box, right panel) is shown enlarged below (scale bar, 5 m). (B) pFIVgag-CFP, pFP93, pMS2-YFP, and pFIV -24. (C and D) pFIVgag-CFP, pFP93, pMS2-YFP, and pFIV -24. Live-cell confocal imaging was performed 48 h a
Ation MDDC are washed and 2 ?105 cells were adsorbed on a microscopy-adapted slide. Cells were incubated with or without HHA-TRITC or GNA-TRITC (200 /ml; Eylabs) at 4 for 30 min. Cells were washed with PBS 0.01 azide 0.5 BSA and then fixed with 1 paraformaldehyde. The coverslides were mounted in Mowiol (SigmaAldrich). Fluorescence analysis was performed with a Zeiss LSM510 confocal microscope

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
