A cryosection of the liver taken from a mouse treated with concanavalin A to induce acute hepatitis features on this issue's cover; the section is stained with Hoechst, Texas red-phalloidin and anti-mIL-33 goat IgG/Cy5-conjugated secondary antibody, identifying the nuclei in blue, F-actin filaments in orange and IL-33-expressing cells in green respectively. The image is taken from the article by Arshad et al. (pp. 2341–2349) in which the induction of IL-33 expression in hepatocytes in concanavalin A-induced hepatitis is suggested to be driven by NKT cells.
