Experimental tools and emerging principles of organellar mechanotransduction

This is the authors' abstract. We don't add key points for this paper.

Mechanotransduction is the process by which cells detect mechanical forces and convert them into biochemical or electrical signals. This process occurs across various cellular compartments, including the plasma membrane, cytoskeleton, and intracellular organelles. While research has focused mainly on force sensing at the plasma membrane, the mechanisms and significance of intracellular mechanotransduction are just beginning to be understood. This review summarizes current techniques for studying organellar mechanobiology, and highlights advances in our understanding of the mechanosensitive events occurring in organelles such as the endoplasmic reticulum (ER), Golgi apparatus, and endolysosomes. Additionally, some open questions and promising directions are identified for future research.
