FIG. 5.
Effect of MV on cell death. Proportion of propidium iodide-staining HIV-1BaL-infected PBMCs (A) or HIV-1IIIB-infected PBMCs (B) 4 days after the addition of Chicago-1 MV (MOI of 1.5 to 0.015) or Edmonston MV (MOI of 15 to 0.15). Controls were equivalent 10-fold dilutions of Vero cell lysate. Background cell death due to HIV-1 alone (3 to 9%) was subtracted. Data are presented as means ± standard errors of the means (error bars) of triplicate wells of PBMCs from two or three donors. ND, not done.
