Expression of various triggering receptors in cultured TAP2^−/− NK cells.

NK cells from patient E.M.O. were cultured in the presence of IL-2 for 15 days and were analyzed by cytofluorometry. (upper panels) Expression of CD16 and NCRs (NKp46, NKp30, and NKp44). (lower panels) Expression of 2B4, NKG2-D, and NKp80. Cells were analyzed by double fluorescence for the expression of NKp46 in combination with CD16 or by single fluorescence for the expression of the other indicated molecules. Comparable results were obtained with NK cells from E.F.A.
