Everybody knows the burning sensation in the legs when climbing down a steep slope for a long time. It is caused by microruptures in the cell membrane of our muscle fibers. These holes in the cell envelopes must be closed as soon as possible as otherwise muscle cells will die off. Researchers were now able to observe this repair process using high-resolution real-time microscopy. It only takes a few seconds until proteins from the inside of the injured cell form a repair patch that finally closes the hole in the membrane. The researchers have now demonstrated that scavenger cells moving around within the muscle virtually perform nano-surgery to remove this repair patch later and restore the normal cell membrane structure.
