Biomimetic Bone Marrow Monocyte Membrane‐Fused Extracellular Vesicles for Targeted Therapy of Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
This study develops a biomimetic delivery system (M‐hEV) by fusing monocyte membranes with extracellular vesicles for targeted therapy of damaged cardiac tissue. The system homes to injured myocardium through specific molecular pathways. In a myocardial infarction model, M‐hEV effectively accumulates in the heart, reduces infarct size, alleviates ...

GLS1 Orchestrates Exosome‐Mediated Tumor‐Endothelial Communication to Facilitate Angiogenesis

open access: yesAdvanced Science, EarlyView.
This study reveals a previously unappreciated, non‐metabolic function of GLS1 in the control of tumor angiogenesis via exosome‐mediated CAV1‐TNC signaling, indicating that therapeutic targeting of GLS1 may offer a dual benefit by simultaneously suppressing tumor metabolic activity and angiogenic processes in head and neck cancer. ABSTRACT Glutaminase 1

Brown Adipocyte Sheets Alleviate Myocardial Ischemia–Reperfusion Injury Through NRG4–ErbB4–Dependent Ferroptosis Inhibition

open access: yesAdvanced Science, EarlyView.
Brown adipocyte sheets are engineered to protect the heart against myocardial ischemia–reperfusion injury by restraining ferroptosis. Upon transplantation onto the cardiac surface, they improve cardiac function, limit infarction and fibrosis, and enhance angiogenesis.

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

open access: yesAdvanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Bandgap‐Engineered PtxTey:Ag2Te Composite Quantum Dots Enable Programmable NIR‐II Imaging and Photothermal‐Immune Synergistic Therapy

open access: yesAdvanced Science, EarlyView.
A bandgap‐engineered PtxTey:Ag2Te quantum dot platform enables tunable NIR‐IIb emission for deep‐tissue imaging and mild photothermal therapy. Conjugation with αPD‐L1 confers dual tumor targeting and real‐time monitoring of PD‐L1 dynamics. Mild photothermal modulation induces immune reprogramming, enhancing checkpoint blockade efficacy and achieving ...
