Instant Membrane Stabilization by Damage‐Triggered Actin Polymerization in Giant Unilamellar Vesicles
Open accessAbstract
Giant unilamellar vesicles (GUVs) rupture catastrophically when membrane pores expand under tension, because they lack cellular repair machinery. Here we present a minimal, damage‐triggered stabilization mechanism based on rapid actin polymerization inside GUVs. ATP‐activated G‐actin was encapsulated in a divalent‐cation‐free lumen while high concentrations of Ca 2+ or Mg 2+ were supplied externally, creating a condition where membrane poration immediately drives cation influx. Upon poration, localized cation entry induces fast F‐actin assembly that forms a cortical‐like meshwork at the defect, mechanically arresting pore enlargement and preserving vesicle morphology for extended periods. The resulting actin plug does not restore full impermeability to small molecules, but it substantially increases vesicle survival against rupture and recapitulates the “plugging” aspect of single‐cell membrane wound responses in a bottom‐up artificial cell model.

Human red blood cell membrane stabilisation is indicative of anti-inflammatory activity.
“Human red blood cells (HRBCs) were used to evaluate membrane stabilisation potential, which is indicative of anti-inflammatory activity (Nguyen et al., 2026;Pinto et al., 2017;Utterström et al., 2022;Zhang et al., 2026).”

The Results section on actin-based stabilization examines membrane damage in giant unilamellar vesicles, not human red blood cells. Searches for HRBCs, erythrocytes, hemolysis, and anti-inflammatory activity found no passage linking red blood cell membrane stabilization to anti-inflammatory activity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
