Retraction Note: Translational Neurodegeneration (2018) 7:25 https://doi.org/10.1186/s40035-018-0128-6

The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding image overlap across various panels in Fig. 8. The authors have stated that incorrect images were used, but have been unable to provide the full raw data. Additionally, the authors could not justify the anesthetic protocol used for rat stereotaxic surgery. The Editor-in-Chief therefore no longer has confidence in the presented data and ethics of this article.

Author Haichen Niu has stated on behalf of all co-authors that they agree to this retraction.
