Retrospective Grid Cells in the Medial Entorhinal Cortex Encode Past Paths During Spatial Navigation

Advanced Science, EarlyView.
Retrospective grid cells are identified in the medial entorhinal cortex, with spatial firing patterns that become most grid‐like when activity is projected onto recently traversed locations. Their coding loses spatial precision in darkness and is disrupted during assisted movement, indicating that entorhinal representations incorporate recent path ...

Cannabinoid CB1 Receptor in Nociceptors Mediates Postoperative Analgesia via ASIC3 Inhibition

Advanced Science, EarlyView.
CB1R and ASIC3 are co‐expressed in CGRP+ nociceptors of mouse DRG. Plantar incision triggers an upregulation of ASIC3 and activation of ASIC3+ neurons, driving mechanical allodynia. CB1R activation suppresses ASIC3 function and downstream ERK1/2 phosphorylation, thereby braking nociceptive signaling and accelerating pain resolution.

Ilexoside K Ameliorates Atherosclerosis by Suppressing CD72hi Macrophages and Blocking CXCL12–CXCR4 Axis to Inhibit Endothelial Pyroptosis

Advanced Science, EarlyView.
CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

A Molecularly Defined Midbrain Circuit Mechanism for Sound‐Driven Defensive Behavior and Anxiety

Advanced Science, EarlyView.
Schematic diagram showing the Cbln2+ ICx–dPAG circuit for sound‐driven defensive and anxiety‐like behaviors. ABSTRACT The innate defense behaviors in response to threatening sounds play a fundamental role in survival. However, the neural circuits that detect threat‐relevant auditory cues and transform them into defensive behaviors remain poorly defined.

SCTR–Expressing Astrocyte–Serotonergic Neuron Signaling Drives Sexual Dimorphism in Depression Through KAT7/H4ac–Foxc2 Epigenetic Axis in an AMPK‐Dependent Manner

Advanced Science, EarlyView.
Astrocytic SCTR modulates depressive‐related phenotypes via AMPKα1, whereas lowered Mt1 blunts Megalin‐dependent AMPKα2 signaling in serotonergic neurons. Diminished AMPKα2 hinders KAT7 nuclear translocation, curtails KAT7 occupancy and H4K8ac at the Foxc2 promoter, and represses Foxc2 transcription, revealing cell‐type‐specific AMPK‐linked epigenetic ...

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

Advanced 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 ...

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

Advanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

In Situ Photo‑Crosslinked Functional Bilayer Hydrogel Modulates Local Microenvironment and Remyelination After Optic Nerve Injury

Advanced Science, EarlyView.
A blue‐light‐crosslinked bilayer hydrogel was developed for local optic nerve repair. The adhesive GM‐Odex outer layer seals and anchors the lesion, while the non‐adhesive GM‐imid inner layer releases MPDA‐Cle without obstructing CSF flow. This system modulates oxidative and inflammatory microenvironments, supports oligodendrocyte differentiation and ...
