Figure 2. NK target cell lysis reduced in autism.

Figure 2

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).
