Fate induction in CD8 CAR T cells through asymmetric cell division

We show that target-induced proximity labelling enables isolation of first-division CD8 chimeric antigen receptor T cells that asymmetrically distribute their surface proteome and transcriptome, resulting in distinct phenotypic, metabolic and functional profiles in proximal and distal daughter cells.
