Vesicle-mediated restoration of a plasmalemmal barrier in severed axons.
Ca(2+)-induced endocytotic vesicles undergo protein-mediated interactions to restore a selectively permeable barrier and propagated action potentials in severed invertebrate giant axons. Similar barrier-restoration phenomena observed in cultured mammalian cells with transected neurites suggest that cellular/molecular mechanisms that repair plasmalemmal damage are phylogenetically conserved.
