NCIt definition : The DNA sequence that encodes the protein cytokine interleukin-2 (IL-2). When introduced
as the complementary DNA (cDNA) form into tumor cells by, for example, a genetically
engineered adenovirus vector, the transfected IL-2 cDNA expresses IL-2 which may activate
antitumoral natural killer cells and elicit an antitumoral cytotoxic T-cell response,
resulting in an inhibition of tumor progression. (NCI04);
