NK cell receptor expression in patients from group 1 following hematopoietic cell transplantation.

Posttransplantation KIR and CD94:NKG2A NK cell expression frequencies for each of the 8 patients from group 1 (one panel per patient) are compared with donor and recipient pretransplantation expression. Patients in group 1 are characterized by a return to donorlike KIR expression by 6 to 9 months after transplantation. Each receptor-specific antibody is shown with a different symbol: EB6 (■; KIR2DL1/S1), DX27 (▪; KIR2DL2-3/S2), DX9 (▵; KIR3DL1), DX31 (▴; KIR3DL2), HP-3B1 (●; CD94), and Z199 (○; NKG2A).
