"These results have broad implications for biological processes regulated by membrane potential, particularly in contexts such as neuronal signaling, where condensate interactions with membranes may play a previously unrecognized regulatory role."

A coordinated recruitment of actin and myosin at large vesicles allows for the "exocytosis by vesicle crumpling" in Drosophila larval salivary glands.

Inès Jmel Boyer covers a preprint from Kumari Kamalesh & team which describes a mechanism that requires precise spatiotemporal control of actomyosin contractility.

Protein serves as a breaking point for cell membrane rupture during cell death

Every day, millions of cells die in our body. Cells do not simply burst at the end of their lives but rather, a specific protein serves as a breaking point for cell membrane rupture. Researchers at the University of Basel have now been able to elucidate the exact mechanism at the atomic level. They have published their results in Nature.
