Proliferative responses in the
WHN−/− patient or theWHN+/− healthy donor brother.(A) Proliferative response evaluated through [3H]-thymidine incorporation after stimulation of peripheral blood mononuclear cells by CD3 cross-linking. PBMCs from the WHN−/−patient were analyzed at regular intervals during the 6 years after allogeneic BMT. The results are expressed as cpm. Dotted lines indicate mean ± SD of control values. (B) Comparison 6 years after BMT of the proliferative response to several mitogens between cells grown in the WHN−/− recipient and in theWHN+/− donor environment. Exogenous rIL-2 was used at a concentration of 100 U/mL.
