We developed a dual-adeno-associated-virus expression system that enables strong and sparse labeling of individual neurons with cell-type and projection specificity. [Paper] [Addgene] AAV-based Sparse Labeling System By directed evolution, we developed a series of AAV vectors, AAV-cMG & AAV-MG, for microglial transgene delivery.
