doi: 10.1016/j.mtbio.2026.103027

Figure Lengend Snippet: A proposed model illustrating the exosome-mediated lncRNA OTUD6B-AS1/miR-128/Notch2 axis in aggravating endometritis. Upon LPS-induced damage, endometrial epithelial cells (EECs) release increased exosomes carrying elevated levels of lncRNA OTUD6B-AS1. These exosomes are taken up by endometrial macrophages. The transferred lncRNA OTUD6B-AS1 acts as a molecular sponge to sequester miR-128, leading to the derepression and upregulation of its target gene, Notch2. The enhanced Notch2 signaling subsequently promotes macrophage polarization towards a pro-inflammatory M1 phenotype, characterized by increased NF-κB activation and iNOS expression, thereby exacerbating endometrial inflammation and tissue damage.
