OBJECTIVE To screen small molecule compounds from traditional Chinese medicine that can enhance recombinant adeno-associated virus(rAAV) transduction.METHODS Recombinant adeno-associated virus(rAAV) has been established as a powerful tool for in vivo gene transfer and achieved much promise in gene therapy applications.However,widespread clinical use has been limited by transduction efficiency.In the current study,we screened a panel of small molecule compound from traditional Chinese medicine focused on AAV intracellular trafficking process and found salvianolic acid B can significantly enhance rAAV2 transduction.RESULTS Salvianolic acid B caused a dose-depen.dent increase in rAAV2 transduction regardless of vector dose,genome architecture,and over a broad range of cell line from various cell type and species(HEK293,HeLa,HepG2,Huh-7,CHO-K1,LO-2).Salvianolic acid B treatment redirected rAAV2 particles toward large vesicles positive for late endosomal(Rab7) and lysosomal(LAMP1) markers.Furthermore,salvianolic acid B acted to increase accumulation of viral particles at the perinuclear region.CONCLUSION In summary,our results suggest that salvi.anolic acid B redirects rAAV2 toward more productive trafficking pathways and stabilizes perinuclear accumulations of vectors,facilitating productive nuclear trafficking. 展开更多
