Phenotype of activated human NK cell populations. (A) CD56^bright CD16^dim NK cells are functionally higher in cytokine production and lymphokine-activated killer activity, and have low ADCC and natural cytotoxicity. (B) CD56^dim CD16^bright NK cells are functionally lower in cytokine production and lymphokine-activated killer cytotoxicity but have high ADCC activity and natural cytotoxicity. + = low expression/functionality, +++ = high expression/functionality.
