Correction to: Nature Medicine https://doi.org/10.1038/nm.2112, published online 14 March 2010.

During the assembly of Supplementary Fig. 8b in the originally published version of this article, one of the bioluminescence images was erroneously duplicated. Treatment [Tx], day 19, “Low sensitivity” was inadvertently pasted into the figure twice, and thus was also shown as Control, day 19, “Low sensitivity”. The original data were located and the figure is now amended via the Supplementary Information included with this amendment.

Supplementary information is available in the online version of this amendment.
