eLife Assessment
This important study presents convincing findings on creating an exhaustive library of new enhancer-AAVs targeting astrocytes and oligodendrocytes with high potential for both basic and translational work, which will be of value to a large and growing community. However, the outdated description of glial biology in the Introduction, the overstated claims of utility in the Conclusion, and the loose stringency in the criteria used to assemble the library diminish the strengths of the claims. The work will be of interest to neuroscientists working on glial cell biology.
