AKAP1 Protects Retinal Ganglion Cells and Preserves Vision by Improving Mitochondrial and Synaptic Health in Glaucomatous Neurodegeneration

Advanced Science, EarlyView.
Intravitreal AAV2‐mediated AKAP1 restoration enhances mitochondrial fusion and biogenesis, improves bioenergetic capacity, and preserves mitochondrial integrity in glaucomatous RGCs. AKAP1 stabilizes presynaptic structure, maintaining synaptic protein expression, and limiting complement‐associated neuroinflammation.

A Biomimetic PLK1 Nanodelivery System Promotes Migrasome‐Mediated Mitocytosis to Restore Efferocytosis and Functional Recovery After Spinal Cord Injury

Advanced Science, EarlyView.
MM‐NPs@PLK1 are formed by encapsulating PLK1 plasmids within CBP5 and coating the nanocomplexes with macrophage membranes. After macrophage‐associated uptake, the NPs@PLK1 enter the cytoplasm and release the PLK1‐encoding plasmid in response to elevated intracellular ROS levels.

Donor‐Cell Senescence Redirects PINK1‐Marked Mitochondrial Cargo From Mitophagy to Microvesicle Transfer Through SUMO3‐Stabilized HSPA9

Advanced Science, EarlyView.
ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

Advanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

pH‐Responsive Nanoplatform‐Mediated Lipid Hijacking and Metabolic Collapse for Synergistic Starvation‐Immunotherapy

Advanced Science, EarlyView.
A pH‐responsive ZIF‐8/2‐DG@Cu‐TA nanoplatform orchestrates multifaceted metabolic disruption for synergistic starvation‐immunotherapy. Acid‐triggered 2‐DG release blocks glycolysis, while Zn2+ overload induces mitochondrial dysfunction. Concurrently, Cx43‐mediated gap junctions redirect lipid droplets from tumor cells to cancer‐associated fibroblasts ...

Tip60‐Mediated USP22 Lactylation Drives Glutamine Metabolic Reprogramming via SLC25A5 in TNBC

Advanced Science, EarlyView.
Tip60‐mediated USP22 K134 lactylation, stabilizing SLC25A5 to enhance glutamine metabolism and α‐KG secretion. The secreted α‐KG drives GPR91‐dependent M2 macrophage polarization, promoting triple‐negative breast cancer progression. Targeting this axis synergizes with CB‐839, offering a promising therapeutic strategy for TNBC.
