IL-4, human recombinant
Interleukin-4 (IL-4), produced primarily by CD4(+) T cells, is an immunomodulatory cytokine, which can inhibit the growth of tumour cells. IL-4 has been known as a Th2 cytokine and can act on B cells, T cells, and monocytes. IL-4 exhibits antitumor activity in rodent experimental gliomas, which is likely mediated by the actions of IL-4 on a variety of immune cells present in and around the tumor masses. Recombinant Human IL-4 produced in E. coli is a single, non-glycosylated polypeptide chain.
