FIG. 3.
IFN-α production by IPC exposed to HIV. (a) IPC production of IFN-α was measured by ELISA 1 day following exposure to HIVBaL with or without the addition of CD40LT. (b) IPC were also incubated with HIVBaL in the presence or absence of neutralizing anti-IFN-α antibody, and p24 production was assessed after 1 week. Error bars represent standard deviations from triplicate wells. Data shown are representative of three experiments. IPC production of RANTES (c) and MIP-1α (d) was measured by ELISA 1 day following exposure to HIVBaL with or without the addition of CD40LT.
