Experiments were done to determine the effect of recombinant interleukin 2 (rIL-2) on mononuclear cells (MC) of newborns and adults. MC were tested for (1) ability to lyse Daudi cells in a 51Cr release assay, (2) cell surface markers using monoclonal antibodies and flow cytometer analysis, and (3) cell types as determined by differential cell counts. Without rIL-2 adults show greater cytotoxicity than newborns in vitro. Incubation with rIL-2 dramatically increased the cytotoxicity expressed with cord blood and adult MC showing equivalent responses. Differences in cell surface markers between newborns and adults prior to rIL-2 exposure were in agreement with those previously published. This study did not demonstrate changes in phenotypes after exposure to rIL-2. Slight changes in differential cell counts occurred after increased incubation periods and rIL-2 exposure.
