NCIt definition : An aerosol formulation of aldesleukin, a recombinant form of interleukin-2 (IL-2),
with potential immunostimulating activity. Upon IL-2 inhalation, this cytokine activates
lymphokine-activated killer cells and natural killer cells, and induces expression
of cytotoxic cytokines, such as interferon-gamma and transforming growth factor-beta.
This may eventually halt tumor cell growth. Localized administration of IL-2 may decrease
toxicity and increase efficacy.;
