A Fluorescence-based Assay for Measuring Phospholipid Scramblase Activity in Giant Unilamellar Vesicles

open access: yesBio-Protocol, 2022
Transbilayer movement of phospholipids in biological membranes is mediated by a diverse set of lipid transporters. Among them are scramblases that facilitate rapid bi-directional movement of lipids without metabolic energy input.

Temperature controlled transformations of giant unilamellar vesicles of amphiphilic triblock copolymers synthesized via microfluidic mixing

open access: yesApplied Surface Science Advances, 2021
We report on a simple approach for synthesis of temperature-responsive giant unilamellar vesicles (GUVs) from poly(N-vinylcaprolactam)15-block-poly(dimethylsiloxane)65-block-poly(N-vinylcaprolactam)15 (PVCL15-PDMS65-PVCL15) triblock copolymer and non ...

GeoV: An Open‐Source Software Package for Quantitative Image Analysis of 3D Vesicle Morphologies

open access: yesAdvanced Intelligent Systems, 2023
Bottom‐up synthetic biology has reconstituted processes like adhesion, cortex formation, or division of giant lipid vesicles (GUVs), which all rely on changes in the vesicle morphology.

Molecular rheometry: direct determination of viscosity in L-o and L-d lipid phases via fluorescence lifetime imaging [PDF]

open access: yes, 2013
Understanding of cellular regulatory pathways that involve lipid membranes requires the detailed knowledge of their physical state and structure. However, mapping the viscosity and diffusion in the membranes of complex composition is currently a non ...

Studying macromolecular composition in cell-cell interfaces using 3D membrane reconstitution systems

open access: yesAdvanced Science, EarlyView.
A comprehensive understanding of the interactions between proteins, lipids and glycocalyx components at the immune synapse is still lacking. Here, an artificial and a semi‐artificial model contact system were established to reconstitute the cell‐cell contact in 3D. The model systems enable the examination of macromolecule enrichment or depletion at the

Bottom-up assembly of functional intracellular synthetic organelles by droplet-based microfluidics

open access: yes, 2020
Bottom-up synthetic biology has directed most efforts toward the construction of artificial compartmentalized systems that recreate living cell functions in their mechanical, morphological, or metabolic characteristics.

Specific Adhesion of Membranes Simultaneously Supports Dual Heterogeneities in Lipids and Proteins [PDF]

open access: yes, 2015
Membrane adhesion is a vital component of many biological processes. Heterogeneities in lipid and protein composition are often associated with the adhesion site. These heterogeneities are thought to play functional roles in facilitating signalling. Here

Light-Switchable Membrane Permeability in Giant Unilamellar Vesicles

open access: yesPharmaceutics, 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-

Shaping Giant Membrane Vesicles in 3D-Printed Protein Hydrogel Cages

open access: yes, 2020
Giant unilamellar phospholipid vesicles are attractive starting points for constructing minimal living cells from the bottom-up. Their membranes are compatible with many physiologically functional modules and act as selective barriers, while retaining a ...
