Toxicity of oxidized phospholipids in cultured macrophages [PDF]

open access: yes, 2012
Background: The interactions of oxidized low-density lipoprotein (LDL) and macrophages are hallmarks in the development of atherosclerosis. The biological activities of the modified particle in these cells are due to the content of lipid oxidation ...

More Than a Question of Correlation: Characterization of the Evidentiary Basis for Biomarker Surrogates Used in European Marketing Authorizations

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Traditionally, clinical outcomes measuring how a patient feels, functions, or survives are preferred endpoints in clinical trials; however, some may take a long time to manifest in slowly developing diseases. Biomarkers, if properly validated, can serve as surrogate endpoints, acting as substitutes for clinical outcomes.

Multiplex analysis of sphingolipids using amine-reactive tags (iTRAQ)

open access: yesJournal of Lipid Research, 2011
Ceramides play a crucial role in divergent signaling events, including differentiation, senescence, proliferation, and apoptosis. Ceramides are a minor lipid component in terms of content; thus, highly sensitive detection is required for accurate ...

Penfluridol targets acid sphingomyelinase to inhibit TNF signaling and is therapeutic against inflammatory autoimmune diseases

open access: yesArthritis Research & Therapy, 2022
Background Penfluridol, isolated from an FDA-approved small-molecule drug library as an inhibitor of tumor necrosis factor α (TNFα)-stimulated NF-κB activation, is clinically used to treat chronic schizophrenia and related disorders.

The p75NTR SIGNALING CASCADE MEDIATES MECHANICAL HYPERALGESIA INDUCED BY NERVE GROWTH FACTOR INJECTED INTO THE RAT HIND PAW [PDF]

open access: yes, 2013
Nerve Growth Factor (NGF) augments excitability of isolated rat sensory neurons through activation of the p75 neurotrophin receptor (p75NTR) and its downstream sphingomyelin signaling cascade, wherein neutral sphingomyelinase(s) (nSMase), ceramide, and ...

Engineering exosomal cargo loading via endogenous molecular pathways: Strategies to enhance therapeutic potential

open access: yesInterdisciplinary Medicine, EarlyView.
This review illustrates how scientists engineer exosomes by hijacking the cell's own cargo‐sorting machinery. These strategies efficiently load therapeutic molecules into natural vesicles, creating powerful next‐generation drug delivery systems (Created with BioGDP.com).

Anxiety and Depression Are Related to Higher Activity of Sphingolipid Metabolizing Enzymes in the Rat Brain

open access: yesCells, 2020
Changes in sphingolipid metabolism have been suggested to contribute to the pathophysiology of major depression. In this study, we investigated the activity of acid and neutral sphingomyelinases (ASM, NSM) and ceramidases (AC, NC), respectively, in ...

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 ...

Hyperresponsiveness of mice deficient in plasma-secreted sphingomyelinase reveals its pivotal role in early phase of host response

open access: yesJournal of Lipid Research, 2013
Plasma secretion of acid sphingomyelinase is a hallmark of cellular stress response resulting in the formation of membrane embedded ceramide-enriched lipid rafts and the reorganization of receptor complexes.

Rethinking our understanding of the pathogenesis of necrotic enteritis in chickens [PDF]

open access: yes, 2009
For decades, low doses of antibiotics have been used widely in animal production to promote growth. However, there is a trend to reduce this use of antibiotics in feedstuffs, and legislation is now in place in Europe to prohibit their use in this way. As
