Reduced numbers of NK cells in BAL of Behçet’s disease. Freshly isolated bronchoalveolar cells from healthy controls, Rheumatoid arthritis patients and BD patients were stained with fluorescein isothiocyanate–conjugated anti-CD3 and phycoerythrin-conjugated anti-CD56 monoclonal antibodies and then analyzed by flow cytometry. Data are shown as box plots. Each box represents the 25^th to 75^th percentiles. Lines inside the boxes represent the mean. Whiskers represent the 10^th and the 90^th percentiles.
