Amantadine-induced reorganization of model SARS-CoV-2 lipid envelopes [PDF]

RSC Advances
Amantadine attracted renewed interest during the COVID-19 pandemic because of its known antiviral activity against influenza A. In this work, we investigated how amantadine affects a simplified model of the SARS-CoV-2 lipid envelope composed of DOPC ...

Population Analysis of Structural Properties of Giant Liposomes by Flow Cytometry

, 2016
We used fluorescence flow cytometry to analyze the structural properties of populations of giant liposomes formed by different preparation methods. The inner aqueous volumes and nominal membrane surface areas of a large number of individual liposomes ...

Giant liposomes as delivery system for ecophysiological studies in copepods.

, 2006
Giant liposomes are proposed as a potential delivery system in marine copepods, the dominant constituent of the zooplankton. Liposomes were prepared in the same size range as the food ingested by copepods (mean diameter of about 7 microm).

α-Synuclein Dimers Impair Vesicle Fission during Clathrin-Mediated Synaptic Vesicle Recycling

Frontiers in Cellular Neuroscience, 2017
α-Synuclein is a presynaptic protein that regulates synaptic vesicle (SV) trafficking. In Parkinson’s disease (PD) and several other neurodegenerative disorders, aberrant oligomerization and aggregation of α-synuclein lead to synaptic dysfunction and ...

Asymmetrical stress generated by the erythrocyte lipid flippase triggers multiple bud formation on the surface of spherical giant liposomes.

, 2010
International audienceProteo-giant liposomes were electroformed from a mixture of lecithin vesicles and inside-out vesicles from erythrocytes. After addition of Mg-ATP in the vicinity of the proteo-giant liposomes, small buds appeared on the liposome ...

A chloride channel from human placenta reconstituted into giant liposomes

, 1995
OBJECTIVE: Ion channels play important roles in epithelial transport, but they are difficult to access for conventional electrophysiologic studies in intact placenta.

Mechanical power is maximized during contractile ring-like formation in a biomimetic dividing cell model

Nature Communications
The spatial and temporal dynamics of forces in cells coordinate essential behaviors like division, polarization, and migration. While intracellular signaling initiates contractile ring assembly during cell division, how mechanical forces coordinate ...

Collapsin Response Mediator Protein 2 (CRMP2) Modulates Induction of the Mitochondrial Permeability Transition Pore in a Knock-In Mouse Model of Alzheimer’s Disease

Cells
Hyperphosphorylated collapsin response mediator protein 2 (CRMP2) is elevated in the cerebral cortex of an APP-SAA knock-in mouse model of Alzheimer’s disease and binds the adenine nucleotide translocase (ANT) in a phosphorylation-dependent manner.

Interaction of two antitumor peptides with membrane lipids - Influence of phosphatidylserine and cholesterol on specificity for melanoma cells.

PLoS ONE, 2019
R-DIM-P-LF11-322 and DIM-LF11-318, derived from the cationic human host defense peptide lactoferricin show antitumor activity against human melanoma. While R-DIM-P-LF11-322 interacts specifically with cancer cells, the non-specific DIM-LF11-318 exhibits ...
