Cover image: Exposure of living astrocytes (transfected to overexpress aquaporin 4 M23 isoform) to neuromyelitis optica-immunoglobulin G (upper panels), but not to control immunoglobulin G (lower panels), leads to clustering/internalization of surface aquaporin 4. Aquaporin 4 stained red; F-actin stained green. See “Effects of neuromyelitis optica-IgG at the blood-brain barrier in vitro.”
