Figure 2. NK target cell lysis reduced in autism.
Mean percent specific K562 lysis is shown for the indicated ratios of NK effector to K562 target cells. Bars represent standard error of the mean. A reduction in cytotoxic activity of cells obtained from ASD subjects was observed at cellular ratios above 1:1, which was significant at the 25:1 NK:K562 ratio (p = 0.02).
