Targeting Dnmt3a/m5C/RelA Axis Attenuates Microglia Inflammatory Response and Improves Postoperative Recovery in Chronic Compressive Cervical Spinal Cord Injury

Advanced Science, EarlyView.
A pro‐inflammatory microglial subset persists after decompression in chronic compressive cervical spinal cord injury and shows enhanced Dnmt3a‐driven m5C signaling. By stabilizing RelA mRNA, this axis sustains NF‐κB activation and postoperative neuroinflammation.

A Brain‐Penetrant Nanobody Reveals GSK3β‐Driven Proline‐Directed Phosphorylation as a Master Regulator of Ischemic Neurodegeneration

Advanced Science, EarlyView.
A brain‐targeted nanoparticle enables delivery of a therapeutic nanobody (Nb.29E9) that inhibits pathogenic GSK3β signaling. This intervention restores AMPK/mTORC1/TGFβ homeostasis, attenuates neuroinflammation and oxidative stress, and promotes long‐term functional recovery after ischemic stroke.

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Protective role of autophagy in neonatal hypoxia–ischemia induced brain injury

Neurobiology of Disease, 2008
Autophagy, an intracellular bulk degradation process of cellular constituents, plays a key role in cell homeostasis and can be induced by stresses, such as nutrient depletion, closed head injury or focal cerebral ischemia. This study focuses on the role of autophagy in neonatal hypoxia-ischemia (HI).

The role of endotoxin, the TNF family of cytokines and intracellular pH in perinatal hypoxic-ischemic brain injury

, 2010
To explore the effect of endotoxin as a sensitising agent prior to neonatal hypoxiaischemia differing doses of endotoxin (E. coli lipopolysaccharide, LPS) were given to neonatal mice prior to hypoxia-ischemia, with sensitising effects noted at dosages ...

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Potassium channel activators protect the N-methyl-D-aspartate-induced cerebral vascular dilation after combined hypoxia and ischemia in piglets

, 1998
Background and Purpose-Cerebral arteriolar dilation to N-methyl-D-aspartate (NMDA) is a neuronally mediated multistep process that is sensitive to cerebral hypoxia and ischemia (H/I).

IRF‐1 modulates hepatic ferroptosis and aggravates liver ischemia/reperfusion injury via DYRK1α

Animal Models and Experimental Medicine, EarlyView.
IRF‐1 modulates hepatic ferroptosis and aggravates liver ischemia/reperfusion injury via DYRK1α. Abstract Background The purpose is to define the contribution of the interferon regulatory factor‐1–dual‐specificity tyrosine phosphorylation‐regulated kinase 1α (IRF‐1–DYRK1α) axis to hepatocellular ferroptosis during liver ischemia/reperfusion injury ...
