Biocatalytic Nanoregulators Restore Joint Redox‐Immune Homeostasis in Rheumatoid Arthritis

Advanced Science, EarlyView.
Mesenchymal stem cell‐derived extracellular vesicles (EVs) coat ruthenium‐loaded metal‐organic frameworks (Ru@ZrMOF), creating a targeted therapeutic (Ru@ZrMOF/EVs). This platform scavenges ROS, generates oxygen, and polarizes macrophages from M1 to M2, alleviating inflammation, inhibiting pannus, promoting cartilage repair, and downregulating HIF‐1α ...

NFS1 Regulates IDH2 to Attenuate Abdominal Aortic Aneurysms via Interacting With SP2

Advanced Science, EarlyView.
The loss of NFS1 leads to its reduced binding with the transcription factor SP2, resulting in decreased expression of the downstream gene Idh2. This causes a shift in energy supply toward glycolysis in VSMCs, ultimately contributing to the occurrence and progression of AAA.

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

Advanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

FAPα+ Macrophages Orchestrate Immune Evasion in Multiple Myeloma by Dual Regulation of PD‐L1 and T Cell Senescence

Advanced Science, EarlyView.
Fibroblast activation protein alpha‐positive (FAPα+) macrophages, a distinct subset of multiple myeloma (MM)‐associated macrophages, drive immune evasion in MM through multi‐faceted mechanisms. FAPα physically interacts with vimentin (VIM) and triggers its phosphorylation at the S72 residue, which in turn induces PD‐L1 transcription. Additionally, FAPα

Nanoscale Mapping of the Subcellular Glycosylation Landscape

Advanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

Advanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Extracellular Vesicle‐Delivered tRF‐His‐GTG‐1 Reprograms Neutrophil Lipophagy and Triggers Inflammation in COVID‐19

Advanced Science, EarlyView.
This study identifies platelet‐derived extracellular vesicles as key immunometabolic regulators in COVID‐19. The delivery of tRF‐His‐GTG‐1 to neutrophils activates TLR8mTOR signaling, disrupts lipophagy, and amplifies NET‐mediated inflammation. Importantly, targeting this axis restores neutrophil homeostasis, offering a potential therapeutic strategy ...
