DC–IFN-β have reduced capacity to induce a mixed lymphocyte reaction.
Naive CD4+ T cells were stimulated with either allogeneic DC or DC–IFN-β (0.1 ng/mL or 1 ng/mL) at the indicated ratios. DC were washed to remove cytokines used for in vitro differentiation. No exogenous cytokines were added to cultures for measurement of [3H]-thymidine incorporation. After 5 days in culture, wells were pulsed with 1 μCi of [3H]-thymidine per well. Twenty-four hours later, plates were harvested and incorporated [3H]-thymidine was measured. Means of triplicate measurements are shown. A representative of 4 independent experiments is shown.
