Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

open access: yesAdvanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

Mapping Embryonic Mouse Lung Development Using Enhanced Spatial Transcriptomics

open access: yesAdvanced Science, EarlyView.
The mammalian lung contains ∼50 cell types arranged along the airway epithelium. Here, deterministic barcoding sequencing (DBiT‐seq) is optimized to nearly double transcript recovery, enabling highly sensitive spatial mapping of the embryonic mouse lung.

Enzyme-treated Asparagus Extract (ETAS) Enhances Memory in Normal Rats and Induces Neurite-outgrowth in PC12 Cells

open access: yesNatural Product Communications, 2017
Enzyme-treated asparagus extract (ETAS) contains various phytochemicals. It has been reported that ETAS protected early cognitive impairment of SAMP8 mice and Aβ-induced reduction of PC12 cell viability. In addition, ETAS had several functions on healthy

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Developmentally Guided Differentiation of Ventral Midbrain Dopaminergic Cells Validated in Proteopathy‐Based Parkinson's Disease Models

open access: yesAdvanced Science, EarlyView.
A developmentally guided protocol reproducibly specifies EN1‐positive ventral midbrain dopaminergic (vmDA) progenitors from human pluripotent stem cells and yields functional vmDA neurons. Optogenetic induction of α‐synuclein aggregation elicits selective degeneration of TH‐positive neurons in 2D cultures and 3D neurospheroids, while transplanted ...

Huntingtin Aggregate‐Responsive Autophagy Gene Circuit Mitigates Disease Pathology in R6/2 Mice

open access: yesAdvanced Science, EarlyView.
CD98‐mediated receptor‐mediated transcytosis enables LIP‐CD98 nanocarriers to cross the blood–brain barrier and deliver ARAA to neurons. mHTT aggregates activate the 11G–NarX sensor, initiating Auto‐P and Trans‐P signaling through the VP48–NarL relay.

Early‐Life Manganese Overexposure Activates Microglial Phagocytosis through the YY1/TREM2 Axis Leading to Hippocampal Synaptic Remodeling in Mice

open access: yesAdvanced Science, EarlyView.
Early‐life manganese exposure induces behavioral deficits and aberrant hippocampal synaptic remodeling by enhancing microglial phagocytosis in young adult male mice. Mechanistically, manganese promotes Yin Yang 1 (YY1)/triggering receptor expressed on myeloid cells 2 (TREM2) signaling through enhanced HIF1α‐mediated transcription and suppressed SMURF2 ...

The Cytoplasmic MicroRNA‐Production Complex Regulates MicroRNA Sorting to Extracellular Vesicles During Synaptogenesis

open access: yesAdvanced Science, EarlyView.
The mechanisms of microRNA cargo sorting to extracellular vesicles, important mediators of cell communication, are not fully understood. This study reveals that the microRNA‐production machinery acts as a ‘hub’ for the sorting of microRNAs to extracellular vesicles, a process regulated by dynamic organelle interactions.

Circulating Exosomes Drive Persistent Neuronal Dysfunction in Post‐Herpetic Neuralgia Patients

open access: yesAnnals of Neurology, EarlyView.
Proposed model of exosome‐mediated neuronal dysfunction in post‐herpetic neuralgia (PHN). (1) Circulating, non‐pathogenic exosomes maintain homeostatic processes in healthy skin, where sensory nerve fibers innervate the epidermis and dermis. (2) During acute zoster, reactivating varicella zoster virus (VZV) travels down neurites to the skin causing ...
