Dynamic shapes of floppy vesicles enclosing active Brownian particles with membrane adhesion [PDF]

open access: yesSoft Matter 19, 3436-3449 (2023), 2023
Recent advances in micro- and nano-technologies allow the construction of complex active systems from biological and synthetic materials. An interesting example is active vesicles, which consist of a membrane enclosing self-propelled particles, and exhibit several features resembling biological cells.

Proteomic comparison defines novel markers to characterize heterogeneous populations of extracellular vesicle subtypes

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance The last decade has seen a rapid expansion of interest in extracellular vesicles (EVs), proposed to mediate cell–cell communication in patho/physiological conditions.

Routes and mechanisms of extracellular vesicle uptake

open access: yesJournal of Extracellular Vesicles, 2014
Extracellular vesicles (EVs) are small vesicles released by donor cells that can be taken up by recipient cells. Despite their discovery decades ago, it has only recently become apparent that EVs play an important role in cell-to-cell communication.

Survival of red blood cells after transfusion: processes and consequences

open access: yesFrontiers in Physiology, 2013
The currently available data suggest that efforts towards improving the quality of red blood cell (RBC) blood bank products should concentrate on: (1) preventing the removal of a considerable fraction of the transfused RBCs that takes place within the ...

Adhesion of vesicles

open access: yesPhysical Review A, 1990
A simple model for the adhesion of vesicles to interfaces and membranes is introduced and theoretically studied. It is shown that adhering (or bound) vesicles can exhibit a large variety of different shapes. The notion of a contact angle governed by tension is found to be applicable only for a restricted subset of these shapes. Furthermore, the vesicle

A Self-Assembled Aggregate Composed of a Fatty Acid Membrane and the Building Blocks of Biological Polymers Provides a First Step in the Emergence of Protocells

open access: yesLife, 2016
We propose that the first step in the origin of cellular life on Earth was the self-assembly of fatty acids with the building blocks of RNA and protein, resulting in a stable aggregate.

SNARE-Mediated Exocytosis in Neuronal Development

open access: yesFrontiers in Molecular Neuroscience, 2020
The formation of the nervous system involves establishing complex networks of synaptic connections between proper partners. This developmental undertaking requires the rapid expansion of the plasma membrane surface area as neurons grow and polarize ...

Membrane-mediated interactions between disk-like inclusions adsorbed on vesicles

open access: yesFrontiers in Physics, 2022
Self-assembly of membrane inclusions plays a key role in biological processes such as cellular signalling and trafficking and has potential applications for designing interfacial devices such as sensors and actuators.

Morphology of Nematic and Smectic Vesicles [PDF]

open access: yesPNAS 2012 109 (14) 5202-5206, 2011
Recent experiments on vesicles formed from block copolymers with liquid-crystalline side-chains reveal a rich variety of vesicle morphologies. The additional internal order ("structure") developed by these self-assembled block copolymer vesicles can lead to significantly deformed vesicles as a result of the delicate interplay between two-dimensional ...
