NK cell repertoire of expression for 2 group 1 patients 3 years after transplantation.

(A,C) These panels show posttransplantation KIR and CD94:NKG2A NK cell expression frequencies for 2 patients from group 1 (SPN 2036 and 2138, respectively) followed for a 3-year time period and compared with donor and recipient pretransplantation expression. Symbols representing receptor-specific antibodies are the same as in Figure 3. (B,D) These panels compare the NK cell repertoires between donor-recipient pairs 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 versus patient 3 years after transplantation (⋄).
