Can Cell Membranes Repair Themselves After Damage?

💡 The Answer

• Yes, cells have mechanisms to reseal membranes following mechanical or chemical damage.
• Calcium influx triggers the rapid recruitment of vesicles to plug the hole and fuse with the membrane.
• Patch repair involves proteins like dysferlin and annexins that help reseal the bilayer.
• Failure of membrane repair can lead to cell death and is linked to muscular dystrophies.
