Redox‐Programmed Activation of a Dual‐Modal Probe for High‐Fidelity Tumor Delineation and Image‐Guided Surgery

open access: yesAdvanced Science, EarlyView.
This study presents a glutathione (GSH)‐activatable dual‐modality probe (GAP9) with a redox‐tuned activation window for precise tumor detection. It remains quenched (“OFF”) in normal tissue yet activates specifically in tumors for T1‐weighted magnetic resonance imaging (MRI) preoperative mapping and near‐infrared II (NIR‐II) fluorescence intraoperative

Oral Celastrol Nanomedicine Targeting Intestinal Antigen‐Presenting Cells to Effectively Mitigate Autoimmune Uveitis via Gut‐Retina Axis

open access: yesAdvanced Science, EarlyView.
Oral nanoCEL exhibits effective intestinal targeting of antigen‐presenting cells and restores the Th17/Treg balance in lymph nodes and spleen, ultimately protecting the blood‐retinal barrier by inhibiting peripheral immune cell infiltration and suppressing retinal glial cell activation.

A Sirtuin‐1‐Targeted Gene‐Activating Tetrahedral DNA Attenuates Bladder Fibrosis by Restoring Mitophagy in Fibroblasts via the SIRT1‐FOXO3‐BNIP3 Axis

open access: yesAdvanced Science, EarlyView.
The SIRT1‐targeted saRNA‐delivering tetrahedral DNA (TSA) treatment effectively upregulates SIRT1 expression, which subsequently promotes FOXO3A deacetylation. This deacetylation event relieves FOXO3A's transcriptional repression on the BNIP3 gene, thereby initiating PINK1‐PARKIN‐dependent mitophagy.

Reprogramming M2b Macrophages via GPX1 Activation by Selenium Nanoparticles Attenuates Lupus Nephritis

open access: yesAdvanced Science, EarlyView.
SeZM NPs selectively target M2b macrophages through mannose–MRC1 (CD206) recognition, enhance GPX1 biosynthesis, and suppress mitochondrial ROS generation, oxidative stress, and JAK–STAT signaling. This dual regulation reduces pro‐inflammatory cytokine release, limits immune cell infiltration and fibrosis, and preserves renal function, providing a ...

Amelioration of Post‐Stroke Edema and Microcirculatory Dysfunction via Targeted AQP4 Inhibition While Preserving the Glymphatic System

open access: yesAdvanced Science, EarlyView.
Compared to untargeted therapy, the targeted nanocarrier, Angiopep‐2‐conjugated Lipid Nanoparticle (A‐LNP) loaded with TGN‐020 (TGN), selectively accumulated in stroke‐injured regions. It suppressed local aquaporin‐4 (AQP4) overexpression, thereby alleviating cerebral edema and hypoperfusion while preserving global glymphatic clearance.
