In the article, "Tumor Necrosis Factor-α Receptor p75 Is Required in Ischemia-Induced Neovascularization" by Goukassian et al (Circulation. 2006;115:752-762), 2 corrections were incorporated into the print version that were not present in the original online version.

(1) In the penultimate sentence of the second paragraph, "interleukin-6" should have read "interleukin-8."
(2)In the last line of the Clinical Perspective, "reception ligation" should have read "receptor activation."

These changes have been incorporated into the current online version of the article. The authors regret this error.
