Whether type I and type II interleukin 4 receptors exert distinct functions in vivo is not known. Using a mouse lacking the type II interleukin 4 receptor component IL-13Rα1, Wynn and colleagues delineate unique functions of this receptor in vivo (p 25). The original image (bottom) captured under polarized light shows diminished collagen content in the liver of an IL-13Rα1-deficient mouse infected with Schistosoma mansoni. Artwork by Lewis Long.
