Immunofluorescent localization of E-cadherin on sections of cryopreserved mouse lung using ECCD-2 antibody, with corresponding light microscopy. Alveoli sections from mice challenged with saline (A) show normal E-cadherin localization of cell-to-cell contacts, not apparent in sections from mice challenged with LPS (B). For more information see article by Evans and colleagues beginning on page 446.
