Description
Interleukin-2 (IL-2) is an alpha-helix cytokine with a molecular weight of 15 kDa. It is a lymphatic factor with strong immune regulation and is produced by T cells in response to antigenicity or mitogenic stimulation. This lymph factor promotes the long-term growth of activated T cells and related cell types. IL-2 plays a role in the activation and proliferation of NK cells, induces the secretion of gamma-interferon and B cell growth factor, and regulates the expression of IL-2 receptor
