Multidimensional Analyses of Donor Memory-Like NK Cells Reveal New Associations with Response after Adoptive Immunotherapy for Leukemia

Mass cytometry reveals an in vivo memory-like NK-cell phenotype, where NKG2A is a dominant checkpoint, and CD8α is associated with treatment failure after ML NK-cell therapy. These findings identify multiple avenues for optimizing ML NK-cell immunotherapy for cancer and define mechanisms important for ML NK-cell function.This article is highlighted in the In This Issue feature, p. 1775.
