Are there published examples of AAV2 being used for in vivo gene transfer?

AAV2 particles generated using the AAVpro series were successfully used for in vivo delivery of a bright fluorescent marker to cells in a very specific brain region in mouse.
Gene transfer into the mouse striatum via recombinant AAV2 particles generated using the AAVpro series.

In addition, AAV2 was used for gene delivery in the following studies (none of these examples use AAVpro products).

Brain
AAV2 used to deliver Cre to the subventricular zone

Brain
AAV2 was used for gene delivery directly to the hippocampus

Liver
AAV2 carrying a gene under the control of a liver-specific promoter was intravenously administered to mice

Pancreas
AAV2 was used for gene delivery to mouse pancreas
