Defect in membrane repair contributes to the development of limb girdle muscular dystrophy type 2B (LGMD2B) and Miyoshi myopathy. In healthy skeletal muscle, unraveling membrane repair mechanisms requires to establish an exhaustive list of the components of the resealing machinery. Here we show that human myotubes rendered deficient for Annexin-A5 (AnxA5) suffer from a severe defect in membrane resealing. This defect is rescued by the addition of recombinant AnxA5 while an AnxA5 mutant, which is unable to form 2D protein arrays, has no effect. Using correlative light and electron microscopy, we show that AnxA5 binds to the edges of the torn membrane, as early as a few seconds after sarcolemma injury, where it probably self-assembles into 2D arrays. In addition, we observed that membrane resealing is associated with the presence of a cluster of lipid vesicles at the wounded site. AnxA5 is present at the surface of these vesicles and may thus participate in plugging the cell membrane disruption. Finally, we show that AnxA5 behaves similarly in myotubes from a muscle cell line established from a patient suffering from LGMD2B, a myopathy due to dysferlin mutations, which indicates that trafficking of AnxA5 during sarcolemma damage is independent of the presence of dysferlin.
