NCIt definition : A recombinant agent chemically identical to or similar to the endogenous cytokine
interleukin-4 (IL-4). Produced primarily by activated T-cells, IL-4 binds to and activates
its cell-surface receptor, stimulating the proliferation and differentiation of activated
B-cells and enhancing their ability to present antigens to T-cells. As a potential
immunotherapeutic agent, binetrakin also augments the effects of other cytokines on
dendritic cells (DC), cytotoxic T lymphocytes (CTL), and tumor-infiltrating lymphocytes
(TIL).;
