Figure Lengend Snippet: Interaction of G3-S16 and G2-NF16 with cellular surface markers. Notes: Activated PBMCs were treated with dendrimers, and levels of CD4, CXCR4, and CCR5 at the cellular surface were followed by flow cytometry. Ratio of iMFI for each surface marker in comparison to nontreated cells is shown (iMFI = % of positive cells × MFI of surface marker). X4 ANTG = CXCR4 antagonist AMD3100; R5 ANTG = CCR5 antagonist TAK779. Both compounds were used as controls (* P <0.05, *** P <0.001 vs control). Data represent the mean ± SD of three independent experiments. Abbreviations: PBMCs, perpipheral blood mononuclear cells; iMFI, integrated mean fluorescence intensity; SD, standard deviation; NT, nontreated.
Article Snippet: Several reagents and ARV were used as controls: zidovudine (AZT; GSK, GlaxoSmithKline plc, London, UK), enfuvirtide (T-20; Hoffman-La Roche Ltd., Basel, Switzerland), atazanavir (ATV; Bristol-Myers Squibb, New York, NY, USA), and raltegravir (RAL; Merck Millipore, Billerica, MA, USA); Suramin, a polyanionic compound that could mimic the function of dendrimers; CXCR4 chemokine receptor antagonist AMD3100, CCR5 receptor antagonist TAK-779, and colchicine, a microtubule polymerization inhibitor (all from Sigma-Aldrich Co., St Louis, MO, USA).
