Coupled assay of sphingomyelin and ceramide molecular species by gas liquid chromatography

open access: yesJournal of Lipid Research, 2002
This study reports a single-step analysis of the molecular species of endogenous ceramides and of the ceramide moiety of sphingomyelins in biological samples, using gas liquid chromatography (GLC).

Secreted sphingomyelins modulate low mammary cancer incidence observed in certain mammals

open access: yesScientific Reports, 2020
Determining mechanisms that naturally protect species from developing cancer is critical in order to prevent and treat cancer. Here, we describe a novel cancer-suppressing mechanism, via the secretion of bioactive factors by mammary cells, that is ...

Placenta‐derived extracellular vesicles: Signal messengers shuttling across the maternal‐fetal barrier

open access: yesInterdisciplinary Medicine, EarlyView.
In normal pregnancy, PEVs help maintain maternal–fetal immune tolerance while enabling controlled immune activation, promote endothelial migration, and support trophoblast invasion and syncytialization, strengthening antimicrobial defense. In pregnancy‐related disorders, dysregulated PEV signaling may drive endothelial dysfunction and hypertension, BBB

Engineered extracellular vesicles for precision renal therapy: Bioengineering strategies and clinical translation

open access: yesInterdisciplinary Medicine, EarlyView.
Engineered extracellular vesicles (EVs) offer a versatile platform for kidney‐targeted therapy. This review summarizes bioengineering strategies, including cargo loading, surface modification, biomimetic fabrication, and biomaterial integration. We highlight translational challenges and propose future solutions to accelerate the clinical application of

Research Advances in Regulatory Effect of Phospholipids on Meat Quality [PDF]

open access: yesShipin Kexue
Phospholipids, a class of polar lipids with complex structure and multiple functions, are composed of glycerophospholipids and sphingomyelins. As an important component of cell membranes, phospholipids are involved in many physiological activities, such ...

Nano Delivery Strategy Opens Effective Avenues for the Treatment of Colorectal Cancer

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT Colorectal cancer (CRC) presents significant therapeutic challenges because of chemoresistance, systemic toxicity, and the complexity of the tumor microenvironment (TME). Nanodrug delivery systems (NDDS) have emerged as versatile platforms capable of overcoming these limitations by enhancing tumor accumulation, improving pharmacokinetics, and ...

Low serum sphingolipids in children with attention deficit-hyperactivity disorder

open access: yesFrontiers in Neuroscience, 2015
Background: Attention deficit-hyperactivity disorder (ADHD) is the most prevalent neuropsychiatric condition in childhood. ADHD is a multifactorial trait with a strong genetic component. One neurodevelopmental hypothesis is that ADHD is associated with a

Uncovering the Complexity of Synucleinopathies: An Ongoing Tale Between Proteins and Lipids

open access: yesMovement Disorders, EarlyView.
Abstract Neurodegenerative diseases are pathological states characterized by progressive alterations in brain homeostasis during aging. Synucleinopathies, including Parkinson's disease and dementia with Lewy bodies, are defined neuropathologically by the accumulation of inclusions known as Lewy bodies and Lewy neurites.

Acid ceramidase overactivity drives ceramide loss, leading to atopic dry skin and Th2‐skewed immune polarization

open access: yesThe Journal of Pathology, EarlyView.
Abstract Ceramide deficiency in the stratum corneum (SC) is a key etiological factor in atopic dermatitis (AD). To clarify the direct role of SC ceramide depletion in impairing SC barrier and water‐holding functions and in initiating AD‐like skin symptoms and disease‐specific molecular alterations, we generated Tg mice overexpressing a mutant form of ...
