Maternal Preconception Antibiotic Exposure Disrupts Microbial Succession: A Transgenerational Risk for Offspring Gut Mucosal Immaturity and Colitis Susceptibility

Advanced Science, EarlyView.
This study reveals that maternal antibiotic exposure prior to conception disrupts intergenerational gut microbial succession. By enhancing maternal‐offspring microbial transmission, altering microbial developmental trajectories and increasing selective pressures during community assembly, these disturbances lead to persistent gut mucosal immaturity and

Thermally Degradable Biocompatible Hydrogel as Transient Encapsulation Coating for Implantable Sensors

Advanced Science, EarlyView.
A biocompatible hydrogel coating with tissue‐like mechanics and reversible dissolution triggered by a mild, physiologically compatible temperature drop (≈37°C → ≈25°C) was developed for the transient encapsulation of implantable devices. The physically crosslinked methylcellulose, polyethylene glycol and polyacrilic acid (MC/PEG/PAA) hydrogel ...

Hierarchical Targeting of TREM2+ Myeloid Cells via Acid‐Triggered OMVs Reprogram Immunosuppression and Suppress Osteolysis in Bone‐Metastatic TNBC

Advanced Science, EarlyView.
This study developed a hierarchical targeting nanoplatform, siTREM2@ETP‐PEOz‐OMVs, against triple‐negative breast cancer (TNBC) bone metastasis. It precisely delivers therapeutic siTREM2 to monocytes/macrophages within the metastatic niche. This intervention dually regulates cell fate: reprogramming immunosuppressive macrophages and inhibiting ...

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

Advanced Science, EarlyView.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

Sirt3 Genetically Engineered Apoptotic Bodies Alleviate Skeletal Aging by Limiting Aggravated NLRP3 Inflammasome Activation of Senescent Macrophages

Advanced Science, EarlyView.
The senescence of macrophages leads to a decrease in the expression of Sirtuin3 (Sirt3), which in turn aggravates the NLRP3 inflammasome activation and IL‐1β secretion, thereby promoting the aging‐related osteoporosis. Sirt3‐enriched apoptotic bodies (ABs‐Sirt3) generated through genetic editing approaches can alleviate skeletal aging by targeting ...
