In the article “Natural killer T cell dysfunction in CD39-null mice protects against concanavalin A-induced hepatitis” (HEPATOLOGY 2008;48:841-852; DOI: 10.1002/hep.22401), the conclusion of the abstract contained an error. The correct conclusion sentences should be:

Conclusion: CD39 and CD73 are novel phenotypic markers of NKT cells. In turn, CD39 expression modulates nucleotide-mediated cytokine production by, and limits apoptosis of, hepatic NKT cells. Deletion of CD39 is protective in Con A-induced hepatitis. This study illustrates a role for purinergic signaling in NKT-mediated mechanisms that result in liver immune injury.
