NSUN2‐Mediated m5C Modification of TGFB1 in Trophoblasts Remodels Macrophage Function to Prevent URSA

Advanced Science, EarlyView.
NSUN2 and m5C decline in URSA villous tissues. Trophoblast Nsun2 ablation disrupts macrophage‐mediated maternal‐fetal tolerance and triggers embryo resorption. Mechanistically, NSUN2‐YBX1 axis stabilizes m5C‐modified TGFB1 mRNA to maintain TGF‐β1 secretion and M2 polarization, and restoring this signaling rescues maternal‐fetal immune tolerance to ...

Experimental Characterization and Validation of a PLECS-Based Hardware-in-the-Loop (HIL) Model of a Dual Active Bridge (DAB) Converter

Energies
Hardware-in-the-loop (HIL) simulation is an essential tool for rapid and cost-effective development and validation of power-electronic systems. The primary objective of this work is to validate and fine-tune a PLECS-based HIL model of a single dual active bridge (DAB) DC-DC converter, thereby laying the foundation for building more complex models (e.g.,

TROP2‐Targeting Chimeras (TRTACs) for Tumor Cell‐Selective Membrane Protein Degradation and Enhanced Drug Delivery

Advanced Science, EarlyView.
TROP2 is identified as a novel tumor‐selective lysosomal‐targeting receptor with established clinical relevance. TROP2‐targeting chimeras (TRTACs) are developed by genetically fusing a TROP2‐binding nanobody to nanobodies against specific target proteins.
