Dynamics of shape fluctuations of quasi-spherical vesicles revisited

open access: yes, 2002
In this paper, the dynamics of spontaneous shape fluctuations of a single, giant quasi-spherical vesicle formed of a single lipid species is revisited theoretically.

Visualization and Quantification of Transmembrane Ion Transport into Giant Unilamellar Vesicles [PDF]

open access: yesAngewandte Chemie International Edition, 2014
AbstractTransmembrane ion transporters (ionophores) are widely investigated as supramolecular agents with potential for biological activity. Tests are usually performed in synthetic membranes that are assembled into large unilamellar vesicles (LUVs). However transport must be followed through bulk properties of the vesicle suspension, because LUVs are ...

Artificial Lipidation of Antifungal Proteins and Antifungal Behavior: A Case Study with Cholesterylation

open access: yesChemBioChem, Volume 26, Issue 11, June 3, 2025.
The antifungal behavior of artificial palmitoylated or cholesterylated chitinase domain is studied from biological, chemical, and physical properties, highlighting the importance of the chemical properties of the lipid moiety covalently attached to chitinase domain to obtain effective antifungal activity by artificial protein lipidation through a ...

Functional Biomaterials Derived from Protein Liquid–Liquid Phase Separation and Liquid‐to‐Solid Transition

open access: yesAdvanced Materials, Volume 37, Issue 22, June 5, 2025.
Protein can undergo liquid–liquid phase separation and liquid‐to‐solid transition to form liquid condensates and solid aggregates. These phase transitions can be influenced by post‐translational modifications, mutations, and various environmental factors.

Lysine acetylation modulates s‐OPA1 GTPase activity and oligomerization in mitochondrial membrane remodeling

open access: yesProtein Science, Volume 34, Issue 6, June 2025.
Abstract Mitochondrial dynamics are regulated by coordinated fission and fusion events that rely on key proteins and lipids organized spatially within the mitochondria. The dynamin‐related GTPase Optic Atrophy 1 (OPA1) is essential for inner mitochondrial membrane fusion and cristae structure maintenance.

A theoretical study on the dynamics of a compound vesicle in linear shear flow [PDF]

open access: yesarXiv, 2018
The dynamics of a nucleate cell in shear flow is of great relevance in cancer cells and circulatory tumor cells where they dominate the dynamics of blood. Buoyed by the success of Giant Unilamellar vesicles in explaining the dynamics of anucleate cells such as Red Blood cells, compound vesicles have been suggested as a simple model for nucleate cells ...

Lichtgetriebener Elektronentransfer durch Phospholipid‐Doppelschichten in anaerober und aerober Atmosphäre

open access: yesAngewandte Chemie, Volume 137, Issue 22, May 26, 2025.
Ein biomimetisches Lipiddoppelschichtmembran‐System ermöglicht einen lichtinduzierten Elektronentransfer durch die Membran unter sowohl aeroben (sauerstoffreichen) als auch anaeroben (sauerstoffarmen) Bedingungen. Der Elektronentransfer wird durch einen organischen Chromophor vermittelt – ein Molekül, das symmetrisch aufgebaut und leicht zu ...

Cardiolipin Structure and Oxidation Are Affected by Ca2+ at the Interface of Lipid Bilayers

open access: yesFrontiers in Chemistry, 2020
Ca2+-overload contributes to the oxidation of mitochondrial membrane lipids and associated events such as the permeability transition pore (MPTP) opening.

Phase Transition Induced Fission in Lipid Vesicles [PDF]

open access: yesBiophysical Chemistry 143 (2009) 106-109, 2010
In this work we demonstrate how the first order phase transition in giant unilamellar vesicles (GUVs) can function as a trigger for membrane fission. When driven through their gel-fluid phase transition GUVs exhibit budding or pearl formation. These buds remain connected to the mother vesicle presumably by a small neck.

Photoinduced Electron Transfer Across Phospholipid Bilayers in Anaerobic and Aerobic Atmospheres

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 22, May 26, 2025.
Light‐driven transmembrane electron transfer across a biomimetic lipid bilayer membrane in aerobic and anaerobic atmospheres is achieved using an organic transmembrane oriented chromophore. The transmembrane molecule is designed symmetrically and easy to synthesize.
