Instant Membrane Stabilization by Damage-Triggered Actin Polymerization in Giant Unilamellar Vesicles. [PDF]

Chembiochem
Damage‐triggered actin polymerization stabilizes membrane pores in giant unilamellar vesicles (GUVs). Membrane poration drives divalent cation influx, inducing rapid F‐actin assembly at the defect site. The resulting actin plug mechanically arrests pore expansion and preserves vesicle morphology, recapitulating the “plugging” phase of single‐cell ...

Use of giant unilamellar lipid vesicles as antioxidant carriers in in vitro culture medium of bovine embryos

Scientific Reports, 2022
Giant unilamellar vesicles (GUVs) are composed of lipophilic layers and are sensitive to the action of reactive oxygen species (ROS). The use of GUVs as microcarriers of biological macromolecules is particularly interesting since ROS produced by gametes ...

Caspase-8 binding to cardiolipin in giant unilamellar vesicles provides a functional docking platform for bid [PDF]

, 2013
Caspase-8 is involved in death receptor-mediated apoptosis in type II cells, the proapoptotic programme of which is triggered by truncated Bid. Indeed, caspase-8 and Bid are the known intermediates of this signalling pathway.

Effects of osmotic pressure on the irreversible electroporation in giant lipid vesicles.

PLoS ONE, 2021
Irreversible electroporation (IRE) is a nonthermal tumor/cell ablation technique in which a series of high-voltage short pulses are used. As a new approach, we aimed to investigate the rupture of giant unilamellar vesicles (GUVs) using the IRE technique ...
