Giant vesicles under oxidative stress [PDF]

Biophysical Journal, 2009
We use optical microscopy to observe giant unilamellar vesicles (GUVs) during the initial steps of membrane oxidative damage. A photo-sensitive molecule consisting of a porphyrine linked to a lipid headgroup (PE-porf) is incorporated in the lipid bilayer, thus generating singlet oxygen at the bilayer surface.

Multiphysics‐Driven Assembly of Biomimetic Vesicles

Advanced Materials, EarlyView.
Artificial extracellular vesicles, derived from cell membranes, are manufactured using a multiphysics‐integrated microfluidic platform that combines nanoknife membrane rupture, herringbone chaotic mixing, and acoustothermal modulation. This standardizable workflow enables the predictable control of vesicle formation and therapeutic loading, while ...

Membrane‐Penetrating Molecular Device Based on a Triplex Containing Acyclic L‐Threoninol Nucleic Acid Functionalized with Cholesterol

Angewandte Chemie, EarlyView.
A membrane‐penetrating molecular device composed of triplex containing cholesterol‐modified acyclic L‐threoninol nucleic acid (L‐aTNA) was achieved. This device is applied to a photo‐triggered signal transduction system functioning on giant unilamellar vesicles. Abstract Membrane‐penetrating molecular devices are valuable biological tools.

Heat-induced formation of single giant unilamellar vesicles [PDF]

, 2011
Giant unilamellar vesicles (GUVs) are an excellent model system for the investigation of lipid membranes, the study of membrane proteins and ion channels in a biomimetic environment, and in the creation of artificial cells.

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

Advanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Light-Switchable Membrane Permeability in Giant Unilamellar Vesicles

Pharmaceutics, 2022
In this work, giant unilamellar vesicles (GUVs) were synthesized by blending the natural phospholipid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) with a photoswitchable amphiphile (1) that undergoes photoisomerization upon irradiation with UV-

Influenza A matrix protein M1 induces lipid membrane deformation via protein multimerization [PDF]

, 2019
The matrix protein M1 of the Influenza A virus (IAV) is supposed to mediate viral assembly and budding at the plasma membrane (PM) of infected cells. In order for a new viral particle to form, the PM lipid bilayer has to bend into a vesicle toward the ...
