Probing compartment-specific sphingolipids with targeted bacterial sphingomyelinases and ceramidases

Journal of Lipid Research, 2019
Sphingolipids contribute to the regulation of cell and tissue homeostasis, and disorders of sphingolipid metabolism lead to diseases such as inflammation, stroke, diabetes, and cancer.

Paradigm of biased PAR1 (protease-activated receptor-1) activation and inhibition in endothelial cells dissected by phosphoproteomics [PDF]

, 2017
Thrombin is the key serine protease of the coagulation cascade and mediates cellular responses by activation of PARs (protease-activated receptors). The predominant thrombin receptor is PAR1, and in endothelial cells (ECs), thrombin dynamically regulates

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Dietary Milk Sphingomyelin Reduces Systemic Inflammation in Diet-Induced Obese Mice and Inhibits LPS Activity in Macrophages

Beverages, 2017
High-fat diets (HFD) increase lipopolysaccharide (LPS) activity in the blood and may contribute to systemic inflammation with obesity. We hypothesized that dietary milk sphingomyelin (SM), which reduces lipid absorption and colitis in mice, would reduce ...

Plasma Glucosylsphingosine in GBA1 E365K, N409S, and L483P Heterozygous Mutation Carriers

Movement Disorders, EarlyView.
Abstract Background GBA1 encodes the lysosomal enzyme glucocerebrosidase, with key substrates that include glucosylceramide and glucosylsphingosine. The E365K variant is the most common variant in GBA1 that is associated with Parkinson's disease (PD) but is not associated with Gaucher disease.

Urologic Bacteriome: The Hero or the Villain in Prostate Cancer Onset, Progression, and Treatment?

Medicinal Research Reviews, EarlyView.
ABSTRACT Prostate cancer (PCa) is the second most frequently diagnosed cancer in men worldwide and the fifth leading cause of cancer‐related mortality, presenting urgent unmet clinical needs in diagnosis and treatment. The recognition of the microbiome as a key factor in human health has prompted numerous studies, revealing an exciting new approach to ...

Intracellular localization of sphingosine kinase 1 alters access to substrate pools but does not affect the degradative fate of sphingosine-1-phosphate[S]

Journal of Lipid Research, 2010
Sphingosine kinase 1 (SK1) produces sphingosine-1-phosphate (S1P), a potent signaling lipid. The subcellular localization of SK1 can dictate its signaling function.

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

The 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 ...

Metabolism of labeled dihydrosphingomyelin in vivo

Journal of Lipid Research, 1968
Tritiated dihydrosphingomyelin was injected into rats, and after various time intervals the distribution of radioactivity in various organs and in the blood and urine was determined.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...
