Figure 1. Inhibition of cell-free HIV-1 by breast milk.

Figure 1

Mature breast milk from HIV-positive (n = 8) and HIV-negative (n = 8) donors was evaluated for inhibition of cell-free HIV-1 in TZM-bl cell assays. Cells were infected with R5 HIV-1BaL in the presence of five-fold serial dilutions of breast milk. Percent inhibition was calculated relative to control cultures infected with HIV-1BaL in the absence of added breast milk. HIV-inhibitory activity of breast milk from HIV-positive (dotted line) and HIV-negative (solid line) donors is shown (mean ± SD).
