Effects of recombinant IFN-α/β on lymphocyte and pDC accumulation in lymphoid tissues. C57Bl/6 mice were injected with 105 U IFN-α, IFN-β, or a combination of 105 U of each IFN. After 18 hours, numbers of lymphocytes and pDCs in the blood, LNs, and spleen were determined by flow cytometry. Averages represent pooled data from 5 mice. *P < .05; ***P < .005.
