An Extracellular Pore‑Targeting Peptide Defines a Designable Allosteric Site in TRPV2

Advanced Science, EarlyView.
Structure‐guided peptide engineering yields Depiv2, a highly potent and subtype‐selective TRPV2 inhibitor that binds to the extracellular pore and remodels it into a closed, non‐conductive state. Depiv2 suppresses pathological cardiac hypertrophy, establishing the TRPV2 outer pore as a designable interface for selective peptide modulation.

SAT1‐Induced Spermidine Depletion Potentiates Food Allergy

Advanced Science, EarlyView.
Spermidine depletion, driven by upregulated spermidine/spermine N1‐acetyltransferase (SAT1), potentiates food allergy by promoting mast cell degranulation through autophagy suppression. SAT1 physically interacts with the long noncoding RNA Cdk19os to inhibit Atg5 and Atg7, disrupting autophagic flux.

Neuron‐Derived Vesicular circMagi1 Restrains Vascular Repair After Ischemic Stroke by Promoting TRIM65‐Mediated ANXA2 Degradation

Advanced Science, EarlyView.
After ischemic stroke, injured neurons transfer circMagi1 to endothelial cells through extracellular vesicles. Within endothelial cells, circMagi1 binds ANXA2 and enhances its engagement with TRIM65, promoting ANXA2 ubiquitination and proteasomal degradation to constrain angiogenic repair.

Developing Highly Effective Nanoparticle mRNA Therapeutic for Pediatric Acute Respiratory Distress Syndrome

Advanced Science, EarlyView.
Sepsis‑induced pediatric acute respiratory distress syndrome suppresses FOXF1 in lung endothelial cells which causes life‐threatening lung damage. To counter this, researchers developed nanoparticles that specifically target these cells and deliver FOXF1 mRNA.

NINJ1 is activated by calcium-driven plasma membrane lipid scrambling during lytic cell death

Abstract NINJ1 is the terminal executioner of cellular rupture in multiple lytic cell death pathways through its clustering in the plasma membrane. Its activation trigger, however, remains unknown. We found that NINJ1-mediated plasma membrane rupture depends on calcium influx into the cell, which suffices to induce NINJ1-mediated ...

Modulation of the TGF‐β/Smad Signaling Pathway by a Bioactive Oxidized Polygonati Rhizoma Polysaccharide Crosslinked Chitosan Hydrogel as Therapeutic Carrier for Parkinson's Disease Treatment

Advanced Science, EarlyView.
An injectable, self‐healing COPRP hydrogel integrates structurally defined oxidized Polygonati rhizoma polysaccharide with carboxymethyl chitosan through dynamic Schiff‐base crosslinking. The bioactive matrix scavenges reactive oxygen species, suppresses neuroinflammation, protects dopaminergic neurons, and supports sustained levodopa release.

Dynamic modulation of auditory hair cell stereocilia membrane mechanics by the scrambling mechanotransduction complex

Summary Inner ear sensory hair cells convert mechanical deflection of their hair bundle into an electrical signal by gating novel mechanoelectrical transduction (MET) channels. Transmembrane channel-like proteins (TMCs) are a component of the MET machinery and part of a superfamily of molecules whose members are ion channels or lipid ...

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

Degrading GPX4 via Biomimetic Nanoparticle‐Mediated In Situ Synthesis of Deep‐Learning‐Designed Binder‐Degron Chimeras for Prostate Cancer Therapy

Advanced Science, EarlyView.
A deep‐learning‐designed binder is fused to a combinatorial degron to create a binder‐degron chimera (bdC) that recruits the CUL2‐RING ubiquitin ligase complex. Encapsulation in a prostate‐cancer‐targeted, CD47‐camouflaged nanocarrier enables tumor‐specific in situ bdC expression, triggering GPX4 degradation and ferroptosis, thereby establishing a ...
