A cell-free assay for detecting HDL that is dysfunctional in preventing the formation of or inactivating oxidized phospholipids

Journal of Lipid Research, 2001
We have developed a novel and rapid cell-free assay of the ability of HDL to prevent the formation of or inactivate oxidized phospholipids. HDL was tested for its ability to inhibit the oxidation of LDL, or inhibit the oxidation of l-α-1-palmitoyl-2 ...

Long‐Term Elevated CO2 Improves Soil Health and Rice Yields in Paddy Fields

Advanced Science, EarlyView.
Combining the two longest‐running rice free‐air CO2 enrichment experiments with a global data synthesis, this study demonstrates that long‐term elevated CO2 consistently enhances soil health. In rice paddies, this improvement sustains the CO2 fertilization effect over decades.

Elevated Apolipoprotein E Expression in Hippocampal Microglia Drives Temporal Lobe Epilepsy Progression

Advanced Science, EarlyView.
In temporal lobe epilepsy, hippocampal APOE is markedly upregulated predominantly in microglia. APOE overexpression in microglia drives TLR4 and cGAS/STING‐dependent neuroinflammation, engages bidirectional crosstalk with neurons and astrocytes, increases neuronal excitability, and perturbs hippocampal lipid metabolism. These findings suggest that APOE‐

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Impact of Intended Isocaloric Early versus Late Time‐Restricted Eating on Plasma Lipidome in Women with Overweight or Obesity: Secondary Analysis of the ChronoFast Trial

Advanced Science, EarlyView.
Women with overweight or obesity follow intended isocaloric early and late time‐restricted eating (TRE) in a crossover trial. Shotgun plasma lipidomics reveals no significant differences between interventions, but identify pronounced lipid changes—including reductions in ceramides and phosphatidylcholines—within the early TRE.

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Single‐Cell RNA Sequencing of Thyroid Tissues Reveals Pathogenesis of Graves' Disease

Advanced Science, EarlyView.
Using single‐cell RNA sequencing and TCR profiling, this study constructed an immune cell atlas in thyroid tissue of Graves’ disease (GD), revealing dominant IFN‐γ‐secreting CD4+ T cells, expanded Tph and CD11c+ B cells, and enriched T/NK cells. Notably, GD thyroid follicular cells (TFCs) activated γδ T cells, which recruited cDC1 cells, suggesting a ...

Profiling of microglia nodules in multiple sclerosis reveals propensity for lesion formation

Nature Communications
Microglia nodules (HLA-DR+ cell clusters) are associated with brain pathology. In this post-mortem study, we investigated whether they represent the first stage of multiple sclerosis (MS) lesion formation.
