NCIt definition : A formulation in which liposomes are loaded with the cytokine interleukin-2 (IL-2).
By activating cytotoxic T-lymphocytes, such as lymphokine-activated killer cells,
and increasing levels of the cytotoxic cytokines interferon-gamma (IFN-gamma) and
transforming growth factor-beta (TGF-beta), IL-2 may exhibit antitumoral activity.
Liposomal formulations of IL-2 may promote entry of the cytokine into target tumor
cells and may be used as an immunoadjuvant in cancer vaccine therapy. (NCI04);
