Cytotoxicity of parental or IL-2 gene–transduced NK cells against NK-sensitive K562 targets or NK-resistant Daudi targets. Cytotoxicity was tested in the absence of exogenous IL-2 in 4- or 24-hour 51Cr-release assays. One representative experiment of 3 performed is shown. *P < .05. (A) NK-92 cells, (B) YT cells.
