NK cell repertoire of expression for 3 group 2 patients 3 years after transplantation.

(A,C,E) These panels show posttransplantation KIR and CD94:NKG2A NK cell expression frequencies for patients in group 2 (SPN 1920, 2068, and 2089, respectively) followed for a 3-year time period. Posttransplantation expression frequencies are compared with donor and recipient pretransplantation expression. Symbols representing receptor-specific antibodies are the same as in Figure 3. (B,D,F) These panels show comparisons between the NK cell repertoires of the donors and patients at different time points following transplantation. Symbols representing each time point under comparison are the same as in Figure 4, with the addition of the following: donor verus patient 3 years after transplantation (⋄).
