Sertoli Cell‐Derived Extracellular Vesicles Orchestrate Cadmium‐Induced Testicular Inflammation and Fibrosis

open access: yesAdvanced Science, EarlyView.
Environmental cadmium exposure disrupts testicular homeostasis through a novel intercellular communication axis. Stressed Sertoli cells release extracellular vesicles carrying damage‐associated molecular patterns and mitochondrial fragments, which activate macrophages via TLR4/NF‐κB signaling.

Directed Evolution Improves the Catalytic Efficiency of APEX2‐Mediated Proximity‐Dependent RNA Labeling

open access: yesAdvanced Science, EarlyView.
ABSTRACT Engineered ascorbate peroxidase APEX2 has been widely used for spatially restricted profiling of subcellular biomolecules, but its catalytic efficiency toward newly developed probes such as biotin‐aniline (Btn‐An) remains suboptimal. To overcome this limitation, we performed yeast surface display‐based directed evolution to enhance APEX2 ...

Cold Gas Plasma Induces Platelet Activation and Hemostasis in Native and Anticoagulated Human Blood

open access: yesAdvanced NanoBiomed Research, EarlyView.
Cold physical gas plasma induces platelet activation and hemostatic responses in native and anticoagulated human blood. Treatment efficacy depends on plasma parameters, including gas composition, distance, and exposure mode, which govern reactive species delivery and energy transfer.
