Recombinant Interleukin-12
Definition 1
A recombinant form of the endogenous heterodimeric cytokine interleukin-12 with potential antineoplastic activity. Recombinant interleukin-12 binds to and activates its cell-surface receptor, stimulating the production of interferon-gamma (IFN) which, in turn, induces IFN-gamma-inducible protein-10 (IP-10) and so inhibits tumor angiogenesis.

Definition 2
One of a group of related proteins made by leukocytes (white blood cells) and other cells in the body. Interleukin-12 is made mainly by B lymphocytes and macrophages. It causes other immune cells to make cytokines and increases the growth of T lymphocytes. It may also block the growth of new blood vessels. Interleukin-12 made in the laboratory is used as a biological response modifier to boost the immune system in cancer therapy. Interleukin-12 is a type of cytokine. (NCI Dictionary)
