IgE-FceRI interactions do not influence susceptibility to R5 HIV infection. A, Relative fold increase in real-time quantitative PCR measurements of expression of HIV SS cDNA expression in 4–5 wk prMCs (R5 virus) and 3–4 wk prMCs (X4 virus) pulsed for 48 h with 100 or 1000 ng/ml IgE and then challenged overnight with R5 or X4-HIV. **, p ≤ 0.017 significant difference between experimental groups; *, p ≤ 0.017 significant difference between untreated (NT) reference controls. B, Relative fold increase in real-time quantitative PCR measurements (histograms and primary y-axis on the left) of HIV SS cDNA expression in LAD2 MCs challenged overnight (18 h) with R5- or X4-HIV before quantitative PCR measurement of SS cDNA. Levels of HIV p24 in culture supernatant fluids from parallel cultures of LAD2 cells infected with either R5 or X4 virus or left uninfected (Media) were determined by ELISA after day 35 in culture (line graph and secondary y-axis on the right).
