rAAV6-mediated miR-29b delivery suppresses renal fibrosis

Background Previous studies showed that microRNA-29b (miR-29b) inhibits renal fibrosis. Therefore, miR-29b replacement therapy represents a promising approach for treating renal fibrosis. However, an efficient method of kidney-targeted miRNA delivery has yet to be established. Recombinant adeno-associated virus (rAAV) vectors have great potential for clinical application. For kidney-targeted gene delivery, the most suitable AAV serotype has yet to be established. Here, we identified the most suitable AAV serotype for kidney-targeted gene delivery and determined that AAV-mediated miR-29b delivery can suppress renal fibrosis in vivo.
