CRISPR/Cas9 technologies have revolutionized our understanding of gene function in complex biological settings, including T cell immunology. Current CRISPR-mediated gene editing strategies in T cells require in vitro stimulation or culture that can both preclude the study of unmanipulated naive T cells and alter subsequent differentiation. In this study, we demonstrate highly efficient gene editing within uncultured primary naive murine CD8+ T cells by electroporation of recombinant Cas9/sgRNA ribonucleoprotein immediately prior to in vivo adoptive transfer. Using this approach, we generated single and double gene knockout cells within multiple mouse infection models. Strikingly, gene deleti..
