Correlated disorder in myelinated axons orientational geometry and structure

, 2017
While the ultrastructure of the myelin has been considered to be a quasi-crystalline stable system, nowadays its multiscale complex dynamics appears to play a key role for its functionality, degeneration and repair processes following neurological ...

Hepatic ENTPD5 Is Critical for Maintaining Metabolic Homeostasis and Promoting Brown Adipose Tissue Thermogenesis

Advanced Science, EarlyView.
ENTPD5‐mediated conversion of extracellular adenosine triphosphate to ADP of hepatocytes is critical for maintaining hepatic glucose/lipid metabolism and promoting brown adipose tissue thermogenesis via the inhibition of adrenomedullin expression and secretion.

Multi‐Region Brain Organoids Integrating Cerebral, Mid‐Hindbrain, and Endothelial Systems

Advanced Science, EarlyView.
Multi‐Region Brain Organoids combine cerebral, mid/hindbrain, and endothelial components into an advanced 3D model capturing 80% of fetal brain cellular diversity. This platform reveals essential endothelial‐neural signaling networks that maintain region‐specific intermediate progenitors during hindbrain development.

Integrated ‘Shield‐Spear’ Biological Patch for Fibrosis‐Free Bladder Reconstruction

Advanced Science, EarlyView.
Fibrosis‐free bladder reconstruction remains challenging. This study pioneers an integrated “shield‐spear” patch: The outer anionic hydrogel layer captures GATA6+ macrophages to suppress collagen overexpression, while the inner S100 aptamer‐engineered EVs target Schwann cells to downregulate the TGFβ/Smad pathway—inhibiting fibrosis with enhanced wound

Myelin basic protein peptide 45–89 induces the release of nitric oxide from microglial cells.

, 2002
Continuous (24 h) exposure of mixed oligodendrocyte/microglial cells to peptides 45–89 derived from citrullinated C8 isoforms of myelin basic protein (MBP) induces cell death.

Mesenchymal Stromal Cells Play an Analgesic Role Through a Npy2r Sensory Neuron‐Mediated Lung‐to‐Brain Axis

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSC) are considered a promising alternative for neuropathic pain (NP) treatment, but underlying mechanisms remain elusive. Huang et al. illustrate that a Npy2r sensory neuron‐related lung–brain axis contributes to MSC analgesia.

Adaptive Antioxidant Nanomedicines Inhibit Ferroptosis in Renal Tubular Epithelial Cells to Alleviate Diabetic Kidney Disease

Advanced Science, EarlyView.
In this study, an adaptive antioxidant nanodrug (AAN) is developed through the self‐polymerization of L‐selenocysteine. The AAN exhibits dual functionalities: antioxidant activity (scavenging reactive oxygen species) and mitochondrial targeting. Moreover, the released selenium (Se) participates in the synthesis of glutathione peroxidase 4 (GPX4), which

Identifying Tipping Points during Healthy Brain Aging through Single‐Nucleus Transcriptomic Analysis

Advanced Science, EarlyView.
This study applies single‐nucleus transcriptomics and systems dynamics to uncover nonlinear aging patterns in healthy human brains. By introducing dynamic network biomarker theory, the authors identify a critical tipping point at ages 56–60 during aging, and highlight glial instability as a key mediator.
