Elevated levels of IFN-α in Flt3L-treated mice.Mobilization of mice with Flt3L results in elevated
levels of IFN-α2 production from (A) BM and (B) spleen cell populations.

Murine IFN-α–producing cells are present in the lymphoid, CD11c+CD11b− DC population.(A)
Myeloid (CD11c+CD11b+) and lymphoid (CD11c+CD11b−) DCs were sorted from spleens of mice
mobilized for 7 days with Flt3L+GM-CSF using the directly conjugated CD11c-PE an...

Major murine IFN-α–producing DC subset expresses a CD11clow, B220+ phenotype and lacks
CD8α expression.(A) Staining of total splenocytes derived from Flt3L+GM-CSF–treated mice
show that, in addition to myeloid CD11c+CD11b+ DC, a subset of CD11c+DC coexpress...

Production of IL-12 (p40) by DC subsets.Total CD11c+ DCs separated by directly conjugated
magnetic beads were stimulated for 24 hours with stimulatory anti-CD40 antibodies (CD40 mAb),
LPS (10 μg/mL), or SAC. For the detection of intracellular IL-12, DCs wer...

FACS profiles showing key markers for isolation of murine plasmacytoid, lymphoid, and myeloid
DCs.Myeloid DCs were obtained by changing the settings for the FACS sorting so that
CD11c+CD8α+ cells were excluded and CD11c+CD11b+ were included.

IFN-α–producing plasmacytoid cells differentiate into DCs after culture in IL-3.Cytospins of
sorted CD11c+B220+ cells were stained using antibodies to MHC class II, a biotinylated goat
anti–rat IgG antibody, and then by streptavidin-alkaline phosphatase and...
