Abstract
The plasma membrane (PM) of eukaryotic cells is constantly exposed to many challenges that can cause wounds that necessitate rapid and efficient repair mechanisms to ensure cell survival. PM wound repair not only encompasses the immediate resealing of the membrane barrier, which involves exocytosis of internal vesicles to deliver membrane, but also subsequent processes that are essential to restore cellular homeostasis. These include restoration of membrane and cortical cytoskeleton structures, as well as replenishment of intracellular organelles consumed during resealing. Recent evidence suggests that the different steps in PM repair, resealing, restructuring, and restoration, are spatiotemporally correlated and regulated by membrane tension. Recent advances in understanding the different phases of PM repair are reviewed and a time-dependent classification of repair mechanisms is proposed.
期刊介绍：
Trends in Cell Biology stands as a prominent review journal in molecular and cell biology. Monthly review articles track the current breadth and depth of research in cell biology, reporting on emerging developments and integrating various methods, disciplines, and principles. Beyond Reviews, the journal features Opinion articles that follow trends, offer innovative ideas, and provide insights into the implications of new developments, suggesting future directions. All articles are commissioned from leading scientists and undergo rigorous peer-review to ensure balance and accuracy.
