Expression data from activated NK cells [RNA]

ABSTRACT: Natural Killer (NK) cells present natural cytotoxicity against tumor cells, although their activity is increased after activation. NK cell activation depends on a complex intracellular signaling process mediated by activating and inhibitory receptors and the functional outcome depends on the integration of the activating and inhibitory signals received. Soluble cytokines and/or ligands on target cells bind the NK cell receptors, and hence, influence the final NK cell response: attack versus ignorance. We used microarrays to detail the global programme of gene expression underlying NK cell activation by IL-2, a MHC-I-deficient target cell (K562)+IL-2 and an EBV-target cell (R69). PBLs from 4 different donors were activated by 100 U/ml IL-2; K562+IL-2 or R69 cells. After 5 days we obtained R
