Modulation of HIV-1 infectivity by galectins. LuSIV cells were infected for 48 h with NL4-3 in the absence or presence of the listed concentrations of galectin-1 and/or -3. Virus infection was evaluated by measuring luciferase activity. Data shown represent the means ± standard errors of the means (SEM) of data for triplicate samples and are representative of three different experiments. The statistical significance of differences between results for untreated/infected and treated/infected cells is denoted by asterisks (***, P < 0.001).
