A request was received from the Research Integrity Officer of the University of Colorado Denver, Anschutz Medical Campus, and by Dr. Clambey, to retract this article: “Adora2b Adenosine Receptor Signaling Protects during Acute Kidney Injury via Inhibition of Neutrophil-Dependent TNF-α Release” by Almut Grenz, Jae-Hwan Kim, Jessica D. Bauerle, Eunyoung Tak, Holger K. Eltzschig, and Eric T. Clambey, The Journal of Immunology, 2012, 189: 4566–4573.

The Editor-in-Chief of The Journal of Immunology was informed that the University of Colorado Denver had conducted a review of the work and concluded that data used for the upper right hand panel of Figure 3B (−Infliximab +Ischemia in a homozygous Adora2b−/− mouse) was duplicated with the upper right hand panel of Figure 3E (−Infliximab +Ischemia in a WT mouse). The authors were not able to provide the original data for these figures, and thus they cannot be validated. There were no findings of scientific misconduct made against any of the coauthors relating to the article. The identified errors appear to be the result of honest error, but due to the lack of original data, the article is hereby retracted.
