On the cover: This image shows α-smooth muscle actin staining (pink) of myofibroblasts together with nuclear staining of phosphorylated STAT-3 (brown) in a lung section from a patient with idiopathic pulmonary fibrosis. Le and colleagues demonstrate that IL-6 trans signaling activates this pathway and plays a role in pulmonary fibrosis. Le, T.-T. T., H. Karmouty-Quintana, E. Melicoff, T.-T. T. Le, T. Weng, N.-Y.
