T-cell growth factor (TCGF) Interleukin-2 precursor IL-2
Aldesleukin, a lymphokine, is produced by recombinant DNA technology and acts as a regulator of the immune response. The biological activities of aldesleukin and native human IL-2, a naturally occurring lymphokine, are comparable. The administration of aldesleukin in murine tumour models has been shown to reduce both tumour growth and spread. The exact mechanism by which aldesleukin-mediated immunostimulation leads to antitumour activity is not yet known.
