To verify the role of CD73 in myocardial inflammation and apoptosis caused by liver fibrosis, mice were injected with AAV9 (adeno-associated virus)-NT5E-cTNT-mCherry to specifically increase the expression of CD73 in myocardial tissue, with the empty AAV9-cTNT-mCherry vector serving as the adeno-associated virus control. Here, NT5E is linked to Hepatic fibrosis.
