A scalable cell-type-specific in vivo platform uncovers neuronal essential genes

CRISPR-based genetic screens are powerful tools to uncover new biology. The Kampmann lab previously pioneered CRISPR screens in human iPSC-derived neurons, astrocytes and microglia in culture (and co-culture). However, some research questions need to be addressed in the context of an intact brain. 

To address this need, a team of researchers in the Kampmann lab, led by Dr. Biswa Ramani and Indigo Rose developed a technology called CrAAVe-seq, which enables highly scalable, yet cell type-specific screens in mouse brains. In a first application, this platform was used to uncover genes required for neuronal survival. 

The results were recently published:
