In the version of this article initially published, some of the arrows along the right side of Figure 1 were incorrect. The arrow from 'Ly6Chi monocyte' to 'pvMΦ long-living' should be deleted, and an arrow should be added from 'Ly6Chi monocyte' into the boxed area above (top right). The error has been corrected in the HTML and PDF versions of the article.
