Coordination of Force-Generating Actin-Based Modules Stabilizes and Remodels Membranes In Vivo

This study observed that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments; linear filaments stabilize fused membranes, while branched filaments, connected by the protein Ezrin, drive integration, demonstrating actin's role in adapting to membrane biophysical changes.

This review discusses the role of Ysc84/SH3yl1 proteins in linking actin regulation to membrane morphology changes but reports no new experimental results.

This study observed that in mouse fetuses, reticular contraction by actomyosin is involved in dermal regeneration, and differences in actin and α-SMA localization may determine the switch between regeneration and scar formation, suggesting potential insights for wound regeneration therapy.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.
