Endothelial Cell‐Based Vascular Bandages for Blood–Brain Barrier Repair and Targeted siRNA Delivery

open access: yesAdvanced Science, EarlyView.
mECs restore blood–brain barrier function after cerebral ischemia–reperfusion by simultaneously targeting, supporting, and regulating the damaged vasculature. mECs home to injured cerebral vessels through interactions with highly expressed VLA‐4, reinforce endothelial integrity by forming new junctions, and, upon OGD‐SN treatment, acquire enhanced ...

Biomimetic Nanomedicine for Senescence‐Modulated Immune Activation Enhances Immunotherapy Efficacy in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
A multifunctional mPDZM nanoplatform is developed in this study. mPDZM integrates chemotherapy‐induced senescence, selective senolysis, and STING‐mediated immune activation. mPDZM effectively clears senescent tumor cells, remodels the tumor immune microenvironment, and enhances antitumor T‐cell responses.

AXL Promotes Ischemic Myelin Repair Through Alleviating Myelin Debris Deposition and Lipid Droplets Accumulation

open access: yesAdvanced Science, EarlyView.
Microglial AXL drives white matter repair after stroke by orchestrating the cleanup of myelin debris. Mechanistically, AXL signals through EGR1 to boost Smpd1 transcription, regulating sphingolipid metabolism and preventing lipid droplet toxicity. Restoring the pathway with ASM therapy mitigates damage, positioning AXL as a key node for therapeutic ...

Gram‐Scale Synthesis of Hafnium‐Rich Carbon Dots for Preclinical Computed Tomography Imaging Across Various Systems

open access: yesAdvanced Science, EarlyView.
Hafnium (Hf)‐rich carbon dots (Hf‐rCDs) with high metal content (40.7%) and robust batch production capacity (>2 g per batch) are synthesized via a facile air‐assisted pyrolysis method. In vivo CT imaging demonstrates outstanding performance of Hf‐rCDs across multiple physiological systems and enables high‐resolution visualization of swine cervical ...

Rod‐Shaped Nanotherapeutics Alleviate Rheumatoid Arthritis by Precisely Disrupting Platelet‐Mediated Pathological Crosstalk via a Morphology‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Owing to the margination effect, rod‐shaped nanoparticles exhibit markedly enhanced co‐localization with endothelial‐adherent platelets (PLTs) under dynamic blood flow. When internalized by PLTs, rod‐shaped PNR@Res inhibit FAK and PI3K/AKT signaling in a morphology‐dependent manner, thereby disrupting their pathological crosstalk with various ...
