Sphinganine‐phosphate prevents influenza infection via promoting CD8+ T cells proliferation and activation

VIEW, EarlyView.
This study established clinical cohorts of respiratory viral infections and identified sphinganine‐phosphate (SA) as a metabolite significantly upregulated post‐infection through metabolomic analysis. In vitro and in vivo experiments demonstrated that SA promotes the generation of effector CD8+ T cells via the SOCS1/JAK1/STAT1 pathway, which ...

Fifty years of lyase and a moment of truth: sphingosine phosphate lyase from discovery to disease[S]

Journal of Lipid Research, 2019
Sphingosine phosphate lyase (SPL) is the final enzyme in the sphingolipid degradative pathway, catalyzing the irreversible cleavage of long-chain base phosphates (LCBPs) to yield a long-chain aldehyde and ethanolamine phosphate (EP).

Update on Non‐Biological and RNA‐Based Therapeutics in Chronic Inflammatory Diseases: Precision Medicine Through Small Molecules: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT In the last decades, critical advancements in research technology and knowledge on disease mechanisms steered therapeutic approaches for chronic inflammatory diseases towards unprecedented target specificity. For allergic and chronic lung diseases, biologic drugs pioneered this goal, acquiring on the way—through the clinical use of monoclonal ...

S1P-S1PR1 Signaling: the “Sphinx” in Osteoimmunology

Frontiers in Immunology, 2019
The fundamental interaction between the immune and skeletal systems, termed as osteoimmunology, has been demonstrated to play indispensable roles in the maintenance of balance between bone resorption and formation. The pleiotropic sphingolipid metabolite,

LPC18:0 Secreted by Exogenous Neural Stem Cells Potentiates Neurogenesis and Functional Recovery via GPR55‐Mediated Signalling in Spinal Cord Injury

Cell Proliferation, EarlyView.
LPC18:0 secreted by exogenous neural stem cells potentiates neurogenesis via the GPR55/AKT/GSK3β signalling axis, which ultimately promotes spinal cord injury recovery. ABSTRACT Spinal cord injury (SCI) is a devastating condition with limited therapeutic options. Although neural stem cell (NSC) transplantation shows regenerative potential, its efficacy

Mechanisms of sphingosine and sphingosine 1-phosphate generation in human platelets

Journal of Lipid Research, 2005
The bioactive molecule sphingosine 1-phosphate (S1P) is abundantly stored in platelets and can be released extracellularly. However, although they have high sphingosine (Sph) kinase activity, platelets lack the de novo sphingolipid biosynthesis necessary

EHD4 and ASAP2 are critical negative regulators of the claudin‐5‐based endothelial barrier

The FEBS Journal, EarlyView.
Cell‐surface CLDN‐5 protein levels can be evaluated using a probe that can bind to the extracellular domains of CLDN‐5. A probe derived from Clostridium perfringens enterotoxin allows us to isolate cells with high CLDN‐5 protein levels from a knockout cell library.

Immune non‐response despite effective antiretroviral therapy in people living with HIV: A review of potential mechanisms, biomarkers and therapeutic approaches

HIV Medicine, EarlyView.
Abstract Introduction A proportion of people living with HIV (PLWH) fail to restore their CD4 count or their CD4/CD8 ratio despite effective antiretroviral therapy (ART). PLWH with immune non‐response (INR) are at a higher risk of both AIDS and non‐AIDS events. The underlying mechanisms of INR remain unclear.
