Partial purification and properties of acid sphingomyelinase from rat liver.

Journal of Lipid Research, 1983
Acid sphingomyelinase was purified approximately 5,200-fold from the mitochondria-lysosome-enriched particles of rat liver by sequential chromatography on DEAE-cellulose, octyl-Sepharose, Sephacryl S-300, Concanavalin A-Sepharose, and CM-cellulose.

Emollient Formulations and Skin Barrier Practices in the Context of Eczema and Food Allergy Prevention

Allergy, EarlyView.
ABSTRACT The skin is far from a passive shield; it functions as a dynamic “living barrier” whose structural and immunological integrity is paramount in preventing atopic dermatitis (AD) and the subsequent progression of the atopic march toward food allergy (FA).

A Curcumin‐Derived HSP70 Inhibitor Disrupts Lysosomal Function to Suppress Triple‐Negative Breast Cancer Progression

Cell Proliferation, EarlyView.
Novel curcumin‐derived M4 binds HSP70's ATPase domain, disrupting HSP70‐mediated lysosomes‐autophagy pathway to inhibit TNBC growth and metastasis, and synergizes with paclitaxel for potent combination therapy. ABSTRACT Structural modification of curcumin yielded a novel series of 1,4‐pentadien‐3‐one oxime ether derivatives, among which compound M4 ...

Mycobacterial Infection is Promoted by Neutral Sphingomyelinase 2 Regulating a Signaling Cascade Leading to Activation of β1-Integrin

Cellular Physiology and Biochemistry, 2018
Background/Aims: Mycobacteria-induced diseases, especially tuberculosis, cause more than 1 million deaths each year, which is higher than any other single bacterial pathogen.

Endothelial cell CD36 regulates membrane ceramide formation, exosome fatty acid transfer and circulating fatty acid levels

Nature Communications, 2023
Endothelial cell (EC) CD36 controls tissue fatty acid (FA) uptake. Here we examine how ECs transfer FAs. FA interaction with apical membrane CD36 induces Src phosphorylation of caveolin-1 tyrosine-14 (Cav-1Y14) and ceramide generation in caveolae ...

Cytotoxicity Profiling of Tenacibaculum Extracellular Products on Chinook Salmon (Oncorhynchus tshawytscha) Gill Cell Line, OTgill1PFR

Journal of Fish Diseases, EarlyView.
ABSTRACT Tenacibaculosis is an important disease of marine fishes caused by bacteria of the genus Tenacibaculum. Pathogenic Tenacibaculum species or serotypes, including Tenacibaculum maritimum, T. dicentrarchi, T. finnmarkense and T. soleae, have been isolated from farmed Chinook salmon (Oncorhynchus tshawytscha) during disease outbreaks in Aotearoa ...

Epithelial IL-33 appropriates exosome trafficking for secretion in chronic airway disease

JCI Insight, 2021
IL-33 is a key mediator of chronic airway disease driven by type 2 immune pathways, yet the nonclassical secretory mechanism for this cytokine remains undefined.

The Pathogenic Sphingolipid Psychosine is Secreted in Extracellular Vesicles in the Brain of a Mouse Model of Krabbe Disease

ASN Neuro, 2022
Psychosine exerts most of its toxic effects by altering membrane dynamics with increased shedding of extracellular vesicles (EVs). In this study, we discovered that a fraction of psychosine produced in the brain of the Twitcher mouse, a model for Krabbe ...

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

Periodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.
