Aberrant Mitochondrial Metabolism in Alzheimer's Disease Links Energy Stress with Ferroptosis

Advanced Science, EarlyView.
Alves et al. reveal how energy loss and oxidative stress, two major features of Alzheimer's disease, are connected. Mitochondria controls the flux of the antioxidant glutathione (GSH), via facilitating both its production and consumption. Energy restriction limits GSH synthesis, conferring vulnerability to cell death by ferroptosis, implicated as a ...

A biophysical observation model for field potentials of networks of leaky integrate-and-fire neurons

, 2012
We present a biophysical approach for the coupling of neural network activity as resulting from proper dipole currents of cortical pyramidal neurons to the electric field in extracellular fluid.

Nasal Delivery of Engineered Exosomes via a Thermo‐Sensitive Hydrogel Depot Reprograms Glial Cells for Spinal Cord Repair

Advanced Science, EarlyView.
Engineered macrophage‐derived exosomes overexpressing GNA12 and GNA13 reprogram glial cells to promote neuroprotection and neural regeneration following SCI. A chitosan‐based thermosensitive hydrogel enables sustained intranasal exosome delivery, bypassing systemic barriers and enhancing therapeutic efficacy.

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

Advanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

Advanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...

Contribution of Prostaglandin E2‐Induced Neuronal Excitation to Drug Resistance in Glioblastoma Countered by a Novel Blood–Brain Barrier Crossing Celecoxib Derivative

Advanced Science, EarlyView.
Glioblastoma (GBM) is an aggressive brain cancer that often recurs and resists chemotherapy. This study found that a chemical called PGE2 causes surrounding brain cells (neurons) to become over‐excited, which makes GBM cells resistant to treatment. Researchers developed a new drug, “Compound 11,” which can cross into the brain and effectively block ...

Neuro‐Cancer Interactions Shape Glioma Intratumoral Heterogeneity

Advanced Science, EarlyView.
This review proposes a conceptual framework for understanding glioma intratumoral heterogeneity shaped by neuro‐cancer interactions: functional patterns and transcriptional states. Functional patterns manifest as three major neural‐like adaptations with spatial and potentially hierarchical relationships, including neurogliomal synapses, glioma networks,
