Effects of a Pulse Electric Field on Electrofusion of Giant Unilamellar Vesicle (GUV)-Jurkat Cell

Journal of Thermal Science and Technology, 2012
Here we describe a new method to deliver membrane impermeable cryo-/lyo-protective agents (CPAs) into the cytosol of living cells via their electrofusion with Giant Unilamellar Vesicles (GUVs) containing large amounts of CPAs.

Block Copolymer Giant Unilamellar Vesicles for High-Throughput Screening

CHIMIA, 2022
Bottom-up synthetic cells offer the potential to study cellular processes with reduced complexity. Giant unilamellar vesicles (GUVs) can mimic cells in their morphological characteristics because their architecture is precisely controllable.

Temperature-Promoted Giant Unilamellar Vesicle (GUV) Aggregation: A Way of Multicellular Formation

Current Issues in Molecular Biology, 2023
The evolution of unicellular to multicellular life is considered to be an important step in the origin of life, and it is crucial to study the influence of environmental factors on this process through cell models in the laboratory.

How universe evolves with cosmological and gravitational constants

Nuclear Physics B, 2015
With a basic varying space–time cutoff ℓ˜, we study a regularized and quantized Einstein–Cartan gravitational field theory and its domains of ultraviolet-unstable fixed point gir≳0 and ultraviolet-stable fixed point guv≈4/3 of the gravitational gauge ...

Imaging the early stages of phospholipase C/sphingomyelinase activity on vesicles containing coexisting ordered-disordered and gel-fluid domains[S]

Journal of Lipid Research, 2011
The binding and early stages of activity of a phospholipase C/sphingomyelinase from Pseudomonas aeruginosa on giant unilamellar vesicles (GUV) have been monitored using fluorescence confocal microscopy.

Alkyl anchor–modified artificial viral capsid budding outside-to-inside and inside-to-outside giant vesicles

Science and Technology of Advanced Materials
The budding of human immunodeficiency virus from an infected host cell is induced by the modification of structural proteins bearing long-chain fatty acids, followed by their anchoring to the cell membrane. Although many model budding systems using giant

Actin crosslinker competition and sorting drive emergent GUV size-dependent actin network architecture

Communications Biology, 2021
By encapsulating proteins in giant unilamellar vesicles, Bashirzadeh et al find that actin crosslinkers, α-actinin and fascin, can self-assemble with actin into complex structures that depend on the degree of confinement.

A Note on Vestigial Osmotic Pressure

Membranes, 2023
Recent experiments have indicated that at least a part of the osmotic pressure across the giant unilamellar vesicle (GUV) membrane was balanced by the rapid formation of the monodisperse daughter vesicles inside the GUVs through an endocytosis-like ...

Assessing membrane material properties from the response of giant unilamellar vesicles to electric fields

Advances in Physics: X, 2023
Knowledge of the material properties of membranes is crucial to understanding cell viability and physiology. A number of methods have been developed to probe membranes in vitro, utilizing the response of minimal biomimetic membrane models to an external ...
