Altered sphingolipid pathway in SARS-CoV-2 infected human lung tissue

open access: yesFrontiers in Immunology, 2023
IntroductionThe SARS-CoV-2 mediated COVID-19 pandemic has impacted millions worldwide. Hyper-inflammatory processes, including cytokine storm, contribute to long-standing tissue injury and damage in COVID-19. The metabolism of sphingolipids as regulators

Development of Comorbid Depression after Social Fear Conditioning in Mice and Its Effects on Brain Sphingolipid Metabolism [PDF]

open access: yes, 2023
Currently, there are no animal models for studying both specific social fear and social fear with comorbidities. Here, we investigated whether social fear conditioning (SFC), an animal model with face, predictive and construct validity for social anxiety

Sphingolipid and ceramide homeostasis : potential therapeutic targets [PDF]

open access: yes, 2012
Sphingolipids are ubiquitous in eukaryotic cells where they have been attributed a plethora of functions from the formation of structural domains to polarized cellular trafficking and signal transduction.

Functional analysis of TOR complex 2 and its control of sphingolipid biosynthesis in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2006
sphingoid base, one of the intermediate of sphingolipids metabolites, plays a key role as a signaling molecule which activate PKH kinases and its substrates YPKs and PKC1 (Casamayor, Torrance et al. 1999; Friant, Lombardi et al.

Regulation of PP2A by Sphingolipid Metabolism and Signaling [PDF]

open access: yesFrontiers in Oncology, 2015
Protein phosphatase 2A (PP2A) is a serine/threonine phosphatase that is a primary regulator of cellular proliferation through targeting of proliferative kinases, cell cycle regulators, and apoptosis inhibitors. It is through the regulation of these regulatory elements that gives PP2A tumor suppressor functions.

Genetic Determinants of Circulating Sphingolipid Concentrations in European Populations [PDF]

open access: yes, 2009
Sphingolipids have essential roles as structural components of cell membranes and in cell signalling, and disruption of their metabolism causes several diseases, with diverse neurological, psychiatric, and metabolic consequences.

Sphingolipid Signaling in Fungal Pathogens [PDF]

open access: yes, 2010
Sphingolipid involvement in infectious disease is a new and exciting branch of research. Various microbial pathogens have been shown to synthesize their own sphingolipids and some have evolved methods to "hijack" host sphingolipids for their own use. For instance, Sphingomonas species are bacterial pathogens that lack the lipopolysaccharide component ...

Loss of Sphingosine Kinase Alters Life History Traits and Locomotor Function in Caenorhabditis elegans

open access: yesFrontiers in Genetics, 2017
Sphingolipid metabolism is important to balance the abundance of bioactive lipid molecules involved in cell signaling, neuronal function, and survival. Specifically, the sphingolipid sphingosine mediates cell death signaling, whereas its phosphorylated ...

Molecular diversity of sphingolipid signalling

open access: yesFEBS Letters, 1997
Sphingolipid breakdown products are now being recognized to play a dual role in cellular signalling, acting as intracellular as well as extracellular signalling molecules. Both types of action may even be found with one sphingolipid species. The recent demonstration of G protein‐coupled receptors with high affinity for sphingosine 1‐phosphate and ...

Fostering Inflammatory Bowel Disease: Sphingolipid Strategies to Join Forces

open access: yesMediators of Inflammation, 2016
Complex sphingolipids are essential structural components of intestinal membranes, providing protection and integrity to the intestinal mucosa and regulating intestinal absorption processes.
