The heterogeneity of small extracellular vesicles and presence of non-vesicular extracellular matter have led to debate about contents and functional properties of exosomes. Here, researchers at the...

Tumour hypoxia is a common feature of solid tumours that contributes to poor prognosis after treatment. This is mainly due to increased resistance of hypoxic cells to radio- and chemotherapy and the association of hypoxic cells with increased metastasis...

Extracellular vesicles (EVs) are involved in numerous processes during infections by both enveloped and non-enveloped viruses. Among them, herpes simplex virus type-1 (HSV-1) modulates secretory...

Researchers of the Neurobiology and Neurophysiology team of the Medicine Faculty at Valencia Catholic University (UCV), headed by Jorge Bacia, have discovered that exosomes – microscopic extracellular vesicles that are released by all cells...

Prions are protein-based infectious agents that autocatalytically convert the cellular prion protein PrPC to its pathological isoform PrPSc Subsequent aggregation and accumulation of PrPSc in nervous...

Exosomes are nanosized membrane vesicles released by fusion of an organelle of the endocytic pathway, the multivesicular body, with the plasma membrane. This process was discovered more than 30 years ago, and during these years, exosomes have gone from being ...

Conditions resulting from loss of cellular homeostasis, including oxidative stress, inflammation, protein aggregation, endoplasmic reticulum stress, metabolic stress, and perturbation of mitochondrial function, are common to many pathological disorders and contribute to aging. Cells face these stress situations by engaging ...
