Purification of neutral sphingomyelinase 2 from bovine brain and its calcium‐dependent activation [PDF]

Journal of Neurochemistry, 2010
J. Neurochem. (2010) 112, 1088–1097.AbstractCeramide is produced by sphingomyelinase (SMase) and it plays a key role in cellular responses such as apoptosis. In this study, we report the purification and characterization of neutral SMase2 (nSMase2) from bovine brain tissue.

Possible involvement of keratinocyte‐derived microvesicle particles in human photosensitivity disorders

Photochemistry and Photobiology, Volume 102, Issue 4, Page 866-876, July/August 2026.
In this model, ROS generated by UVB result in PAFR agonists acting upon the PAFR resulting in MVP generation release via the enzyme aSMase. In photosensitivity, there are increased ROS, resulting in augmented PAF agonists and increased MVP release. This process can be blocked by aSMase inhibitors.

Biogenesis of JC polyomavirus associated extracellular vesicles

Journal 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)

miRNA Sensor HuR Compartmentalizes Ago2‐Uncoupled miRNAs to Lipid Droplets to Buffer miRNA Activity in Mammalian Cells

The FASEB Journal, Volume 40, Issue 11, 15 June 2026.
This study revealed a dose‐dependent miRNA buffering mechanism involving extracellular export and storage of miRNA on lipid droplets. The protein HuR facilitates miRNA buffering by dissociating miRNAs from Ago2 and promoting miRNA accumulation on lipid droplets or its extracellular export, depending on cellular requirements.

Inhibition of nSMase2 Reduces the Transfer of Oligomeric α-Synuclein Irrespective of Hypoxia

Frontiers in Molecular Neuroscience, 2019
Recently, extracellular vesicles (EVs), such as exosomes, have been proposed to play an influential role in the cell-to-cell spread of neurodegenerative diseases, including the intercellular transmission of α-synuclein (α-syn). However, the regulation of

Inhibition of neutral sphingomyelinase-2 restrains enterovirus 71 infection by autophagy

Microbial Pathogenesis
Enterovirus 71 (EV-71) is a major pathogenic factor that causes hand, foot, and mouth disease in young children and infants. Given the limited treatments for EV-71 infection, discovering new host factors and understanding the mechanisms involved will aid in combating this viral infection.

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

Journal 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.

Endogenous Engineering Reprograms Extracellular Vesicles for Enhanced Therapeutic Function

Advanced Science, Volume 13, Issue 36, 29 June 2026.
This review explains how Extracellular vesicles‐producing cells can be endogenously engineered to load therapeutic proteins and nucleic acids. We summarize physiological and genetic strategies that harness native sorting pathways for selective cargo loading.

HDL‐mimetic peptide treatment reverses APOE4‐induced transcriptomic and lipidomic alterations in the brain of humanized APOE mice

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION The apolipoprotein E4 (APOE4) allele is the strongest genetic risk factor for late‐onset Alzheimer's disease (AD). ApoE4 has reduced lipidation capacity and impaired lipid transport, disrupting neuronal maintenance. The high‐density lipoprotein (HDL)‐mimetic peptide 4F offers a potential therapeutic strategy.
