Extracellular Vesicles: Classification, Biological Functions, Diseases, and Therapeutic Opportunities

open access: yesMedComm, Volume 7, Issue 10, October 2026.
• EV content maintains cellular homeostasis and is involved in several disease onset and progression. • miRNA export in EVs depends on: RNA‐binding proteins recognizing motif sequences and on epitranscriptomic modifications. • The disclosure of delivery mechanisms is crucial for developing personalized EV‐based therapeutic tools. ABSTRACT Extracellular

Pharmacological Inhibition of Small Extracellular Vesicle Secretion by ALK5i SD‐208 via Lysosomal Rerouting of CD63+ Compartments

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 9, September 2026.
ABSTRACT Pharmacological tools to selectively modulate extracellular vesicle (EV) secretion are scarce. Here, we identify the ALK5 (TGF‐β receptor I) inhibitor SD‐208 as a potent suppressor of small EV (sEV) secretion that acts independently of its canonical anti‐fibrotic activity.

Src regulates cigarette smoke-induced ceramide generation via neutral sphingomyelinase 2 in the airway epithelium. [PDF]

open access: yesAm J Respir Cell Mol Biol, 2015
We previously demonstrated that the neutral sphingomyelinase (nSMase) 2 is the sole sphingomyelinase activated during cigarette smoke (CS)-induced oxidative stress of human airway epithelial cells, leading to ceramide generation and subsequent apoptosis ...

GW4869 Depletes Macrophages and Increases Number of Extracellular Vesicles in Murine Peritoneal Cavity Fluid

open access: yesJournal of Extracellular Biology, Volume 5, Issue 9, September 2026.
ABSTRACT Pharmacological strategies to modulate extracellular vesicle (EV) release in vivo are gaining traction, yet their broader effects on local immune microenvironments remain unclear. In this study, we assessed how repeated intraperitoneal (i.p.) dosing of the neutral sphingomyelinase inhibitor GW4869 reshapes the peritoneal cavity.

Withanolide D induces apoptosis in leukemia by targeting the activation of neutral sphingomyelinase-ceramide cascade mediated by synergistic activation of c-Jun N-terminal kinase and p38 mitogen-activated protein kinase

open access: yesMolecular Cancer, 2010
Background Ceramide is an important second messenger that has diverse cellular and biological effect. It is a specific and potent inducer of apoptosis and suppressor of cell growth.

When EV Dose Is Not What It Seems: Quantitative Mismatch Between Particle Number‐ and Protein‐Based Dosing

open access: yesJournal of Extracellular Biology, Volume 5, Issue 9, September 2026.
Created with BioRender.com. ABSTRACT Extracellular vesicles (EVs) are widely studied as mediators of intercellular communication, yet their quantitative characterization remains inconsistent. In this study, we investigated how vesicle release rate, cellular proliferation, and tumour origin jointly shape EV‐associated protein output. Using a panel of 19

Role and regulation of neutral sphingomyelinase-2 in response to DNA damage [PDF]

open access: yes, 2015
Neutral sphingomylinase-2 (nSMase2) is a ceramide-generating enzyme that has been implicated in growth arrest, apoptosis and exosome secretion. In this thesis, we show that doxorubicin induces a dose-dependent induction of nSMase2 mRNA and protein levels

Biogenesis of JC polyomavirus associated extracellular vesicles

open access: yesJournal of Extracellular Biology, 2022
JC polyomavirus (JCPyV) is a small, non‐enveloped virus that persists in the kidney in about half the adult population. In severely immune‐compromised individuals JCPyV causes the neurodegenerative disease progressive multifocal leukoencephalopathy (PML)

Molecular Mechanisms and Therapeutic Applications of Extracellular Vesicles in Remodeling of the Skin Cancer Niche

open access: yesNano Select, Volume 7, Issue 9, September 2026.
Extracellular vesicles at the nexus of skin cancer progression and precision therapy. EVs orchestrate tumor microenvironment remodeling through cargo‐mediated intercellular communication, immune modulation, angiogenesis, and extracellular matrix reorganization, while also emerging as next‐generation platforms for targeted drug delivery, biomarker ...

Inhibition of neutral sphingomyelinase‐2 perturbs brain sphingolipid balance and spatial memory in mice [PDF]

open access: yesJournal of Neuroscience Research, 2010
AbstractThe sphingolipid ceramide is a bioactive signaling lipid that is thought to play important roles in modulating synaptic activity, in part by regulating the function of excitatory postsynaptic receptors. However, the molecular mechanisms by which ceramide exerts its effects on synaptic activity remain largely unknown.
