FIG. 3.
Inhibition of p24 antigen production in HIV-1-infected PBMCs after the addition of measles virus (MV) at different time points. Chicago-1 MV or Edmonston MV (MOI of 0.15) was added to PBMCs infected with CCR5-tropic HIV-1BaL (A) or CXCR4-tropic HIV-1IIIB (B) 3 h before HIV-1 infection, concurrently with HIV-infection (0 h), or 15 h after HIV-1 infection. The levels of p24 antigen (Ag) were measured after 96 h. Experiments were performed in duplicate with PBMCs from three to five donors, and data are presented as means ± standard errors of the means (error bars). The value that is significantly different (P < 0.05) between MV and the corresponding dilution of Vero cell lysate is indicated by an asterisk.
