Research Field: CNS

AAV Serotype: AAV-PHP.eB

Dose: A dose of 1 × 10^13 vector genomes (vg) virus was obtained for animal injection.

Routes of Administration: In order to find the vessel, two white mice were injected in the tail vein, while the virus was delivered through the prefrontal lobe in two black mice assisted with a brain stereotaxic apparatus

Targeted organ: brain

Animal or cell line strain: 8-week-old male C57BL mice with body weight of 250–300 g.


Objective To verify the neurotypicality of AAV-PHP.eB after tail vein injection in adult mice and its efficiency in crossing the blood-brain barrier(BBB).Methods The rAAV-SYN-GFP plasmid was constructed, and adult C57 BL mice were injected with AAV PHP.eB: SYN-GFP in the tail vein(300 nL, virus titer 3 × 10~9 vg) and in the prefrontal lobe(50 L, virus tite5 × 10~(11) vg). The green fluorescent protein(GFP) signal in the brain was observed at two weeks, while the GFP signal in the peripheral organs was observed at four weeks. Results Two weeks after tail vein injection, GFP expression was observed throughout the brain especially in the cortex, hippocampus, and geniculate nucleus. No GFP signal was observed or detected by western blotting in the peripheral organs after four weeks. GFP signal was observed mainly at the loca site after prefrontal lobe injection.Conclusion AAV-PHP.eB: SYN-GFP can effectively cross the BBB in adult mice. Using a neuron-specific promoter allows exogenous gene expression in neurons; therefore, AAV-PHP.eB can be used as an effective carrier for studying diseases in the central nervous system(CNS).
