How PROLEUKIN Works

Aldesleukin functions as an interleukin-2 lymphocyte growth factor that activates cellular immunity and produces multiple dose-dependent immunological effects. It enhances lymphocyte mitogenesis and cytotoxicity while inducing the activity of natural killer and lymphokine-activated killer cells. Additionally, the drug stimulates the production of various cytokines, including interferon gamma, tumor necrosis factor, and interleukin-1, to inhibit tumor growth.
