Profiling of Integrin Isoforms on Lung‐Tropic Exosomes by Spectrally and Kinetically Multiplexed Single‐Molecule Imaging

Advanced Science, EarlyView.
A spectrally and kinetically multiplexed single‐molecule imaging method is developed, which achieved simultaneous imaging of 12 exosomal proteins at an unparalleled single‐copy resolution. It is found that co‐occurrence of α6 integrin and the pairing β counterpart on single exosomes is essential for lung targeting, providing valuable information for ...

Periodontitis Induces B Cell‐Macrophage Crosstalk to Exacerbate Glucose Dysregulation in Obesity

Advanced Science, EarlyView.
In obesity, periodontitis exacerbates hyperglycemia and exhibits a liver‐centric preference for glucose regulation. This occurs through a periodontitis‐driven circuit between pathogenic B cells and hepatic macrophages. Their reciprocal expansion, orchestrated by the NLRP3/IL‐18 signaling pathway, amplifies metabolic inflammation and disrupts glucose ...

Neutrophil‐Mimetic Nanoscavengers Target the Inflammatory Microenvironment to Eliminate NETs/ROS and Immunomodulate cGAS‐STING Signaling in Septic AKI

Advanced Science, EarlyView.
Sepsis‐associated acute kidney injury is driven by oxidative stress, NETs overproduction, and dysregulated innate immunity. Here, we develop neutrophil‐mimetic nanoscavengers that integrate ROS‐scavenging Mn3O4 nanozymes with DNase‐1‐mediated NETs degradation to suppress cGAS‐STING signaling, reprogram macrophage polarization, and effectively alleviate

Artificial Piezoelectric Interface Enables Ultrafast Interfacial Ion Kinetic for Highly‐Sensitive Piezoionic Sensors

Advanced Science, EarlyView.
This study proposes a piezoelectric interface modification strategy to amplify the piezoionic effect. The piezoelectric interface generates an intrinsic electric field, which not only drives rapid ion migration but also concentrates polarized ions on the interface. The flexible sensor delivers superior performance, such as a quick response rate, strong
