Abstract:
Sphingolipids play a key structural role in cellular membranes and/or act as signaling molecules. Inherited defects of their catabolism lead to lysosomal storage diseases called sphingolipidoses. Although progress has been made toward a better understanding of their pathophysiology, several issues still remain unsolved. In particular, whether lysosphingolipids, the deacylated form of sphingolipids, both of which accumulate in these diseases, are simple biomarkers or play an instrumental role is unclear. In the meanwhile, evidence has been provided for a high risk of developing malignancies in

Abstract:
Isomeric lysosphingolipids, galactosylsphingosine (GalSph) and glucosylsphingosine (GlcSph), are present in only minute levels in healthy cells. Due to defects in their lysosomal hydrolysis, they accumulate at high levels and cause cytotoxicity in patients with Krabbe and Gaucher diseases, respectively. Here, we show that GalSph and GlcSph induce lysosomal membrane permeabilization, a hallmark of lysosome-dependent cell death, in human breast cancer cells (MCF7) and primary fibroblasts.

Abstract:
Schizophrenia is a mental disorder with a prevalence of 0.7–1% of the general population and is characterized by impaired dopamine transmission in neurons. Recent data have shown that lysosomal storage disorders (LSD), characterized by a decrease in enzyme activity and a corresponding accumulation of substrate in lysosomes due to mutations in lysosomal genes, can manifest a wide range of clinical symptoms including psychosis, affective disorders, early onset dementia and schizophrenia. The purpose of this study was to assess the level of lysosphingolipids in patients with schizophrenia, Parkin

Abstract:
Human neutrophils, when exposed to soluble stimuli, aggregate, release oxygenated products of arachidonic acid and generate active oxygen species. Sphingolipid-derived products such as sphingosine and lysosphingolipids have been shown to exert selective actions on a variety of cell types, including neutrophils. Therefore, to determine the structural basis for selective inhibition of neutrophil responses by naturally occurring sphingolipids, seven compounds were prepared by total organic synthesis, and their impact on neutrophils in suspension has been studied. The compounds synthesized include

Abstract:
Ceramides are key components of the skin's permeability barrier. In atopic dermatitis, pathological hydrolysis of ceramide precursors - glucosylceramides and sphingomyelin - into lysosphingolipids, specifically glucosylsphingosine (GS) and sphingosine-phosphorylcholine (SPC), and free fatty acids (FFAs) has been proposed to contribute to impaired skin barrier function. This study investigated whether replacing ceramides with lysosphingolipids and FFAs in skin lipid barrier models would exacerbate barrier dysfunction. When applied topically to human stratum corneum sheets, SPC and GS increased

Abstract:
Abstract Background Lysosphingolipids, the N-deacylated forms of sphingolipids, have been identified as potential biomarkers of several sphingolipidoses, such as Gaucher, Fabry, Krabbe and Niemann-Pick diseases and in GM1 and GM2 gangliosidoses. To date, different methods have been developed to measure various lysosphingolipids (LysoSLs) in plasma. Here, we present a novel liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for a simultaneous quantification of LysoSLs (HexSph, LysoGb3, LysoGM1, LysoGM2, LysoSM and LysoSM509) in dried blood spot (DBS). This LC-MS/MS method was used
