TGF-β1-dependent downregulation of NKp30, NKp46, NKG2D, and DNAM-1 expression on NK cells. Purified NK cells from healthy donors were seeded in 96-well plates supplemented with 1000 U/ml rhIL-2 for 48 hours with or without 10 ng/ml rhTGF-β, and the expression of NKp30, NKp46, NKG2D, and DNAM-1 on NK cells were detected by flow cytometry ().
