Figure 2. DC TLR ligand responsiveness.
Panels A and B. CD86 MFI and HLA-DR MFI on isolated MDC following overnight culture in presence of Medium and poly I∶C stimulation in healthy control (n = 21) and HIV+ subjects (n = 18). The p value in panel B is for comparison between the delta HLA-DR MFI for controls and HIV infected subjects . IL-6 production from isolated MDC on a subset of the same subjects (n = 18 control and n = 16 HIV+) (panel C) following overnight culture in absence and presence of poly I∶C stimulation. IL-6 production from isolated PDC on a subset of the same subjects (n = 17 control and n = 17 HIV+) (panel D) following overnight culture in absence and presence of R848 stimulation. Healthy control (n = 17) and HIV+ subject (n = 16) PDC IFN-α production in response to overnight R848 stimulation is shown in panel E. Panel . Association between MDC spontaneous IL-6 production and HIV plasma level.
