Analysis of BST2 expression and potential BST2–ILT7 cis-interaction. (A) HEK293, NHDF, HUVEC, and HaCat cells, cultured in the absence or presence of 500 units/ml of IFN-α for 48 h, were stained with anti-BST2 mAb 26F8. Staining with isotype-matched control Ig is shown in the gray shaded area. Data are representative of three independent experiments. (B) Fresh isolated pDCs from peripheral blood or cells activated with various stimuli for 48 h were analyzed for surface BST2 expression by flow cytometry. Data are representative of two independent experiments. (C) Human Burkitt’s lymphoma Namalwa cells transduced with different pDC receptor complexes, i.e., BDCA2/FcϵRIγ or ILT7/FcϵRIγ, were analyzed for surface BST2 and ILT7 expression. Data are representative of three independent experiments.
