In the version of this article initially published, some of the text on p 882 was inaccurate. The correct text should read as follows: “thereby counteracting the beneficial effects of blocking IAPP on islet inflammation” (middle column) and “This mechanism has been suggested to mediate ROS-dependent inflammasome activation induced by high concentrations of glucose in mouse pancreatic beta cells12, although this finding is now being debated” (right column, first full paragraph, second sentence). The errors have been corrected in the HTML and PDF versions of the article.
