Polystyrene Nanoplastics Drive β‐Cell Dedifferentiation Through Dendritic Cell‐Intrinsic MHC‐I‐Dependent Inflammatory Crosstalk

open access: yesAdvanced Science, EarlyView.
Polystyrene nanoplastics disrupt pancreatic immune–endocrine homeostasis by promoting MHC‐I‐associated dendritic cell activation and inflammatory crosstalk with β cells. This immune remodeling drives β‐cell dedifferentiation, impairs insulin secretion, and aggravates metabolic dysfunction, revealing a previously unrecognized immunometabolic mechanism ...

Plaque‐Hepatic Targeting Nanotherapy Disrupts the PCSK9‐LOX‐1 Axis to Suppress oxLDL in Atherosclerosis

open access: yesAdvanced Science, EarlyView.
Self‑amplifying PCSK9–LOX‑1 feedback axis drives atherosclerotic progression by promoting oxLDL generation and endothelial uptake. A dual‑targeting nanoplatform (siPCSK9@PEAL NPs‑aL) is constructed to simultaneously silence hepatic PCSK9 for lipid lowering and block plaque LOX‑1 for anti‑inflammation.

Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

open access: yesAdvanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.

Endothelial miR‐15a/16‐1 Regulation of SYNE1 Mediates Structural and Functional Recovery after Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Endothelial miR‐15a/16‐1 deletion promotes long‐term recovery after traumatic brain injury by restoring SYNE1 expression. Enhanced endothelial SYNE1 preserves vascular integrity, protects white and gray matter, and improves neurological function. The endothelial miR‐15a/16‐1–SYNE1 axis emerges as a key regulator of neurovascular repair and a potential ...

Dual‐line Genome‐scale CRISPR Screening Enables Robust Target Gene Discovery

open access: yesAdvanced Science, EarlyView.
A species‐optimized CRISPR platform integrates efficient piggyBac delivery, genome‐scale sgRNA libraries, and parallel screening in two independently engineered Bactrocera dorsalis Cas9 cell lines. Cross‐line consensus analysis filters line‐specific effects, enriches candidates with reproducible in vivo phenotypes, and reveals conserved, species ...

Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

open access: yesAdvanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...
