Decreased DCIR expression in IM-MDDCs by siRNA treatment. IM-MDDCs were either left untreated (control), transfected with a control siRNA, or transfected with a DCIR-specific siRNA. After 40 hours, flow cytometry analysis of DCIR was performed using a combination of PE-labeled anti-DCIR and isotype-matched control Ab. Data shown correspond to a single experiment representative of 7 independent experiments.
