Hierarchical Nanoplatform Integrating Oxidative–Acidic Microenvironment Remodeling and Bone Homeostasis Modulation for Diabetic Bone Defect Therapy

Advanced Science, EarlyView.
A hierarchical CM/LDH nanoplatform integrates ROS‐scavenging Ce‐MOF nanozymes with acid‐neutralizing CaAl‐LDH and is delivered within GelMA hydrogel to diabetic bone defects. By remodeling the oxidative‐acidic microenvironment, preserving mitochondrial homeostasis, and suppressing mtDNA–cGAS–STING inflammatory signaling, CM/LDH reduces proinflammatory ...

Co‐activation of Selective Nicotinic Acetylcholine Receptor Subtypes Is Required for Neuroprotection against Alzheimer's Disease

Advanced Science, EarlyView.
ABSTRACT Beta‐amyloid peptide (Aβ)‐induced suppression of hippocampal GABAergic interneuron activity drives hyperexcitability, amyloid pathology, and cognitive impairment in Alzheimer's disease (AD), suggesting that enhancing hippocampal inhibition may be protective.

Astrocytes Coordinate Neurovascular Coupling During Prolonged Sensory Demand via AQP4/TRPA1/BEST1/D‐Serine Signaling

Advanced Science, EarlyView.
Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

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 ...
