Endocytosis brings closure to epithelial wounds

Epithelial cells bordering a wound respond by forming two types of actin-based structure: dynamic membrane protrusions that help the cells crawl into the wound and/or seal it and an actomyosin cable that encircles the wound and closes it like a purse string. Matsubayashi et al. reveal that the endocytic remodeling of intercellular adherens junctions promotes Drosophila epidermal wound healing by coordinating the activity of multiple actin regulators at the wound edge. This biosights episode presents the paper by Matsubayashi et al. from the August 3rd, 2015, issue of The Journal of Cell Biology and includes an interview with the paper's senior author, Tom Millard (University of Manchester, Manchester, UK). Produced by Caitlin Sedwick and Ben Short. See the associated paper in JCB for details on the funding provided to support this original research.
