In the supplemental data of the May 1, 2007, issue, the authors failed to cite the source material in the legend for Figure S1. The attribution with Figure S1 should have read: “The preceding is a reprint of Fig. 5A in Zhu, D. et al Deactivation of phosphatidylinositol 3,4,5-trisphosphate/Akt signaling mediates neutrophil spontaneous death. Proc Natl Acad Sci U S A. 2006;103(40):14836–14841. © 2006 National Academy of Sciences, U.S.A.”

The error was corrected in the online “Supplemental Figures and Videos” data supplement.
