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‐

Dinucleoside polyphosphates : newly detected uraemic compounds with an impact on leucocyte oxidative burst [PDF]

, 2009
Background. Dinucleoside polyphosphates (NpnN) have pathophysiologic roles in cardiovascular disease and are newly detected uraemic retention solutes. They were retrieved in human plasma, tissues and cells.

MicroRNA‐Enriched Plant‐Derived Exosomes Alleviate Colitis by Modulating Systemic Immunity, Metabolic Homeostasis, and Gut Microbiota

Advanced Science, EarlyView.
Herbal medicine, with its multicomponent and multitarget potential, is often studied primarily for traditional forms, especially phytochemicals. Currently, ulcerative colitis lacks natural, low‐toxicity therapies, yet emerging research highlights plant‐derived exosomes as a promising option.

Onion‐Mitochondria Inhibit Lipopolysaccharide‐Induced Acute Lung Injury by Shaping Lung Macrophage Mitochondrial Function

Advanced Science, EarlyView.
Proposed model of orally administered onion mitochondria (O‐Mit) uptake by lung macrophages and fuse with macrophage mitochondria (M‐Mit). This fusion reprograms the metabolism of dysfunctional M‐Mit in lipopolysaccharide‐induced murine acute lung injury by modulating dynamin‐related protein 1 (DRP1) phosphorylation and cardiolipin peroxidation ...

Biomedical Applications of Nanozymes: An Enzymology Perspective

Angewandte Chemie, EarlyView.
With a lens of enzymology, this review compares nanozymes with enzymes using the Michaelis‐Menten model and differences in KM and kcat along with catalysis in complex biological environment. The implications of these differences in biomedical applications of nanozymes are then described with a statistical analysis of the trend of therapeutic use of ...

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

Advanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

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,

Sequence‐Specific Installation of Aryl Groups in RNA via DNA‐Catalyst Conjugates

Angewandte Chemie, EarlyView.
DNA oligonucleotides carrying amine nucleophilic catalysts are employed to deliver aryl groups to complementary sites in RNA under physiological conditions. The strategy can be used to sequence‐specifically label protein‐coding RNAs, or to knock down expression selectively, with potential applications in basic transcriptome research and in future ...

Structural Analyses of Toll-like Receptor 7 Reveal Detailed RNA Sequence Specificity and Recognition Mechanism of Agonistic Ligands

Cell Reports, 2018
Summary: Toll-like receptor 7 (TLR7) is an innate immune receptor for single-stranded RNA (ssRNA) and has important roles in infectious diseases. We previously reported that TLR7 shows synergistic activation in response to two ligands, guanosine and ...
