CXCL11 and hepatocellular carcinoma: Among the different tested AAVs, only the novel AAV capsid mutant AAV2-DWPATY and the murine brain EC-targeted variant AAV-BR1 transduced human brain microvascular EC more efficiently than HepG2 human hepatoma cells (Fig. 6C; AAV2-DWPATY: 5.6-fold expression ratio HBMEC/ HepG2).
