MiRNAs are small noncoding RNAs vital for protein regulation and gene expression. Since their discovery in the early nineties, many of their intracellular roles have been characterized. However, it is only recently that EVs loaded with miRNAs and other molecular ...

Extracellular vesicles (EVs) are a class of membranous vesicles that are released by multiple cell types into the extracellular environment. This unique class of extracellular organelles which play pivotal role in intercellular communication are conserved across prokaryotes and eukaryotes. Depending ...

Extracellular vesicles (EVs) are a heterogeneous group of structures which can be classified into smaller in size and relatively homogenous exosomes (EXSMs)-spherical fragments of lipid bilayers from inner cell compartments-and bigger in size ectosomes (ECSMs)-a direct consequence of cell-membrane blebbing. ...

Cell senescence is associated with the secretion of many factors, the so-called “senescence-associated secretory phenotype”, which may alter tissue microenvironment, stimulating the organism to clean up senescent cells and replace them with newly divided ones. Therefore, although no longer dividing, ...

Exosomes and ectosomes, extracellular vesicles of two types generated by all cells at multivesicular bodies and the plasma membrane, respectively, play critical roles in physiology and pathology. A key mechanism of their function, analogous for both types of vesicles, is ...

For cell-to-cell communication, all living cells including archaea, bacteria, and eukaryotes secrete nano-sized membrane vesicles into the extracellular space. These extracellular vesicles harbor specific subsets of proteins, mRNAs, miRNAs, lipids, and metabolites that represent their cellular status. These vesicle specific ...

Secreted membrane-enclosed vesicles, collectively called extracellular vesicles (EVs), which include exosomes, ectosomes, microvesicles, microparticles, apoptotic bodies and other EV subsets, encompass a very rapidly growing scientific field in biology and medicine. Importantly, it is currently technically challenging to obtain a ...

Telocytes have been reported to play an important role in long-distance heterocellular communication in normal and diseased heart, both through direct contact (atypical junctions), as well as by releasing extracellular vesicles (EVs) which may act as paracrine mediators. Exosomes and ...
