PBMCs were stimulated for 3h with 150ng/ml PMA + 1µM ionomycin in RPMI
plus brefeldin A and monensin (eBioscience), 2.5µg/ml
anti-CD107α,
1.25µg/ml
anti-CD107b (BD Bioscience), and 10µM
TAPI-2 (VWR
International). Following stimulation, cells were resuspended in cytometry buffer (PBS +
0.05% sodium azide + 2mM EDTA + 2% fetal calf serum) and stained with
isotope-tagged antibodies before being acquisition on the CyTOF. For the detailed protocol
