EXTRACELLULAR VESICLES AND THEIR THERAPEUTIC APPLICATIONS: A REVIEW
Background & Aims: Extracellular vesicles are double phospholipid layer vesicles releasing from several cells. These particles contain bio-molecules including mRNA, miRNA, DNA, proteins, and lipids which play a pivotal role in the cell to cell communication. Once delivered, they participate to change target cell function, fate, morphology, differentiation, and growth. The present study is a re...
متن کاملExploding vesicles
While studying fatty acid vesicles as model primitive cell membranes, we encountered a dramatic phenomenon in which light triggers the sudden rupture of micron-scale dye-containing vesicles, resulting in rapid release of vesicle contents. We show that such vesicle explosions are caused by an increase in internal osmotic pressure mediated by the oxidation of the internal buffer by reactive oxyge...

In This Issue In This Issue Monitoring MLCK yosin light chain kinase (MLCK) is a busy protein— it phosphorylates myosin's regulatory light chain (and thus activates myosin) during nonmuscle cell contraction, cytokinesis, stress fiber formation, and motility. In general, MLCK is known to be present at the cellular sites implicated in these events, but the results of Chew et al. (page 543) are so...
متن کاملSynaptic vesicles
Aside from forming ion channels, what else do claudins do? Claudins and occludin (also a four-pass integral membrane protein) interact laterally in the membrane circumscribing the cell to form a ‘fence’. This barrier prevents the diffusion of extracellularly facing lipids between apical and basolateral plasma membrane domains. The tight junction may also be an important component of several sig...
متن کاملPolymer vesicles.
Vesicles are microscopic sacs that enclose a volume with a molecularly thin membrane. The membranes are generally self-directed assemblies of amphiphilic molecules with a dual hydrophilic-hydrophobic character. Biological amphiphiles form vesicles central to cell function and are principally lipids of molecular weight less than 1 kilodalton. Block copolymers that mimic lipid amphiphilicity can ...
