Boron Nitride Nanomaterials Trigger Immunomodulatory Effects in Human Broncho‐Epithelial Cells by Modulating Eicosanoid Lipid Signaling

Advanced Science, EarlyView.
This study demonstrates that BNNT exposure disrupts lipid homeostasis in bronchial epithelial cell cultures and activates eicosanoid lipid biosynthesis, producing inflammatory lipid mediators like leukotrienes. These effects are more pronounced in asthmatic cell cultures compared to healthy ones.

Spatially Resolved Multiomics Reveals Metabolic Remodeling and Autophagy Activation in Adamantinomatous Craniopharyngiomas

Advanced Science, EarlyView.
Multiomics integration analysis reveals the “cystic fluid–tumor cell” metabolic coupling that mediates active choline/ethanolamine uptake of tumor cells from cystic fluid and PC/PE synthesis pathways reprogramming that mediating autophagy pathway activation within ACP. ABSTRACT Adamantinomatous craniopharyngioma (ACP), a benign yet highly recurrent and

Lipid phosphate phosphatases and signaling

Journal of Lipid Research, 2009
Lipid phosphate phosphatases (LPPs) regulate cell signaling by modifying the concentrations of lipid phosphates versus their dephosphorylated products. The ecto-activity regulates the availability of extracellular lysophosphatidate (LPA) and sphingosine ...

Experimental Activation of Endocannabinoid System Reveals Antilipotoxic Effects on Cardiac Myocytes

Molecules, 2020
Hypertension coincides with myocardial alternations in lipid (including sphingolipids) and glucose metabolism. The latest data indicate that accumulation of metabolically active lipids, especially ceramide (CER) and diacylglycerol (DAG) significantly ...

Diacylglycerol kinase ζ controls diacylglycerol metabolism at the immunological synapse

Molecular Biology of the Cell, 2011
Diacylglycerol (DAG) generation at the T cell immunological synapse (IS) determines the correct activation of antigen-specific immune responses. DAG kinases (DGKs) α and ζ act as negative regulators of DAG-mediated signals by catalyzing DAG conversion to phosphatidic acid (PA). Nonetheless, the specific input of each enzyme and their spatial regulation

Engineering Immune Cell to Counteract Aging and Aging‐Associated Diseases

Advanced Science, EarlyView.
This review highlights a paradigm shift in which advanced immune cell therapies, initially developed for cancer, are now being harnessed to combat aging. By engineering immune cells to selectively clear senescent cells and remodel pro‐inflammatory tissue microenvironments, these strategies offer a novel and powerful approach to delay age‐related ...

Mechanisms of Mitochondrial Toxicity and Cytotoxicity Caused by Pseudomonas aeruginosa Pyocyanin in Human Nasal Epithelial Cells

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Pseudomonas aeruginosa is an opportunistic pathogen in cystic fibrosis‐related chronic rhinosinusitis (CF‐CRS) that produces phenazine metabolites pyocyanin and 1‐hydroxyphenazine (1‐HP), which may have detrimental effects on mitochondria, reactive oxygen species (ROS), Ca2+ signaling, and apoptosis.

Sphingomyelin synthase 1 activity is regulated by the BCR-ABL oncogene[S]

Journal of Lipid Research, 2013
Sphingomyelin synthase (SMS) produces sphingomyelin while consuming ceramide (a negative regulator of cell proliferation) and forming diacylglycerol (DAG) (a mitogenic factor). Therefore, enhanced SMS activity could favor cell proliferation.

Hydroxycarboxylic Acid Receptor 2 Mediates β‐hydroxybutyrate's Antiseizure Effect in Mice

Annals of Neurology, EarlyView.
A Objective The ketogenic diet, a high‐fat, low‐carbohydrate regimen, is often used to treat drug‐resistant seizures and is being studied for Alzheimer's disease and other neuropsychiatric disorders. However, its mechanism of action remains unclear. β‐hydroxybutyrate, a primary circulating ketone body produced by the ketogenic diet, may mediate its ...
