Please note that an error appeared in the online early release version of this article. The final html, pdf, and print versions have been corrected. For reference, the correction appears below.

The authors regret that an acknowledgment was left out of the first sentence of the Mice section under Materials and methods. The sentence should have read: “TSAd (+/+) and (−/−) C57BL/6 mice were obtained from Dr. Jeff Bluestone (University of California, San Francisco, San Francisco, CA) and were bred in our laboratory (4).”

Also, Fig. 2 contained a labeling error. In panels A and B, all instances of “100” should have read “150.” The corrected figure and its legend appear below.
