Advancing Biotherapeutic Treatment of Ulcerative Colitis Using Lipid Mesophases: Formulation Design and Preclinical Validation

Advanced Science, EarlyView.
Lipid mesophases provide a versatile platform for colon‐targeted delivery of biotherapeutics, protecting them from degradation while enhancing mucoadhesion and enabling localized, controlled release to the inflamed mucosa after oral or rectal administration. In a DSS‐induced colitis model, this strategy reduced disease activity, inflammatory biomarkers,

Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

Advanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

pH‐Responsive Nanoplatform‐Mediated Lipid Hijacking and Metabolic Collapse for Synergistic Starvation‐Immunotherapy

Advanced Science, EarlyView.
A pH‐responsive ZIF‐8/2‐DG@Cu‐TA nanoplatform orchestrates multifaceted metabolic disruption for synergistic starvation‐immunotherapy. Acid‐triggered 2‐DG release blocks glycolysis, while Zn2+ overload induces mitochondrial dysfunction. Concurrently, Cx43‐mediated gap junctions redirect lipid droplets from tumor cells to cancer‐associated fibroblasts ...

Tip60‐Mediated USP22 Lactylation Drives Glutamine Metabolic Reprogramming via SLC25A5 in TNBC

Advanced Science, EarlyView.
Tip60‐mediated USP22 K134 lactylation, stabilizing SLC25A5 to enhance glutamine metabolism and α‐KG secretion. The secreted α‐KG drives GPR91‐dependent M2 macrophage polarization, promoting triple‐negative breast cancer progression. Targeting this axis synergizes with CB‐839, offering a promising therapeutic strategy for TNBC.

Lactate Drives Pathological Browning of White Adipose Tissue to Aggravate Sepsis‐Associated Metabolic Disorders in a GPR81‐Dependent Manner

Advanced Science, EarlyView.
Sepsis‐triggered lactate accumulation induces pathological white adipose tissue browning. Lactate activates adipocyte GPR81 to sequentially upregulate CTRP6‐p38 signalling and UCP1 expression. This cascade exacerbates sepsis‐associated metabolic disorders.

Role of endogenous lipid droplets in lipolysis in rat adipocytes.

Journal of Lipid Research, 1994
Sonication of rat fat cells caused an increase in lipolysis in the absence of lipolytic stimulants (basal lipolysis) and loss of epinephrine responsiveness.

Impact of Galactolipids and Phosphatidylcholine on the Stability of Microalgal Oil‐In‐Water Emulsions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Microalgal oil is a sustainable source of omega‐3 polyunsaturated fatty acids. However, it is very sensitive to lipid oxidation, especially in emulsions. While the presence of phospholipids and galactolipids in microalgal oil can influence its oxidation, their impact in oil‐in‐water emulsion is not yet fully understood. This study investigates

Effects of sphingomyelin and cholesterol on lipoprotein lipase-mediated lipolysis in lipid emulsions

Journal of Lipid Research, 1998
Lipoprotein lipase (LPL) hydrolyzes triacylglycerol (TG) of TG-rich lipoproteins. We investigated the effects of sphingomyelin (SM) and cholesterol (Chol) on the lipolysis of lipid emulsions by LPL using human apolipoprotein C-II (apoC-II) or plasma as ...
