Elongation of H60a reduces NK cell lysis in vitro. Untransfected RMA cells (UN), RMA+H60a, RMA+H60a-CD2 and RMA+H60a-CD4 cells expressing similar levels of ligands were used as targets for (A) IL-2-expanded NK cells or (B) ex vivo B6 NK cells in ⁵¹Cr release assays at the indicated effector to target (E:T) ratios. Data show mean+SD (n=4). ^*Two-tailed p values from unpaired t tests of significant difference are indicated for the data columns (20:1 E:T ratio). Data are representative of five (A) and two (B) independent experiments.
