Ubiquitous macropinocytosis in anthozoans

eLife, 2020
Transport of fluids, molecules, nutrients or nanoparticles through coral tissues are poorly documented. Here, we followed the flow of various tracers from the external seawater to within the cells of all tissues in living animals.

Survival of red blood cells after transfusion: processes and consequences

Frontiers 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 ...

Spontaneous Expulsion of Giant Lipid Vesicles Induced by Laser Tweezers [PDF]

, 1996
Irradiation of a giant unilamellar lipid bilayer vesicle with a focused laser spot leads to a tense pressurized state which persists indefinitely after laser shutoff.

Mechanisms of Exocytosis

Acta Biologica Slovenica, 2009
Vesicles are cellular organelles, in which signaling molecules (neurotransmitters or hormones) are stored and are essential for the function of neurons and endocrine cells in supporting the communication between tissues and organs.

Considerations for Measuring Activity-Dependence of Recruitment of Synaptic Vesicles to the Readily Releasable Pool

Frontiers in Synaptic Neuroscience, 2019
The connection strength of most chemical synapses changes dynamically during normal use as a function of the recent history of activity. The phenomenon is known as short-term synaptic plasticity or synaptic dynamics, and is thought to be involved in ...

Extracellular RNA in oncogenesis, metastasis and drug resistance

RNA Biology
Extracellular vesicles and nanoparticles (EVPs) are now recognized as a novel form of cell–cell communication. All cells release a wide array of heterogeneous EVPs with distinct protein, lipid, and RNA content, dependent on the pathophysiological state ...

Soft Confinement for Polymer Solutions

, 2014
As a model of soft confinement for polymers, we investigated equilibrium shapes of a flexible vesicle that contains a phase-separating polymer solution.

Extracellular vesicles

GENETICS
Abstract Extracellular vesicles (EVs) encompass a diverse array of membrane-bound organelles released outside cells in response to developmental and physiological cell needs. EVs play important roles in remodeling the shape and content of differentiating cells and can rescue damaged cells from toxic or dysfunctional content. EVs can send

Extracellular Vesicles and Their Membranes: Exosomes vs. Virus-Related Particles

Membranes, 2023
Cells produce nanosized lipid membrane-enclosed vesicles which play important roles in intercellular communication. Interestingly, a certain type of extracellular vesicle, termed exosomes, share physical, chemical, and biological properties with ...
