| Description: |
circUbe3a was elevated in M2 macrophage-derived small extracellular vesicles compared with M0 macrophage-derived small extracellular vesicles, based on circRNA microarray screening and RT-qPCR confirmation after primary macrophage isolation and polarization. Functional experiments supported that M2M-SEV-derived circUbe3a mediates communication with cardiac fibroblasts and promotes fibrosis-related fibroblast changes. |
