背景
-
Interleukin-21 (IL-21) belongs to the Type I four helix bundle cytokines, and shares the common cytokine receptor gamma chain with IL-2, IL-4, IL-7, IL-9, and IL-15. IL-21 is expressed by CD4+ T cells, natural killer (NK) T cells, and Th17 cells, and the IL-21 receptor is highly expressed on CD4+ and CD8+ B cells, indeed, IL-21 plays a pivotal role in the survival and proliferation of B cells, and their differentiation to immunoglobulin (Ig) producing cells. IL-21 up-regulates and down-regulates the production of IgG1 and IgE by B cells, respectively, and diminishes the severity of allergy and asthma. In some case, IL-21 also induces the apoptosis of B cells. The other roles of IL-21 include regulation of innate immune systems, implication on autoimmunity, and antitumor actions.Recombinant human Interleukin-21 (rhIL-21) produced in E. coli is a single non-glycosylated polypeptide chain containing 132 amino acids. A fully biologically active molecule, rhIL-21 has a molecular mass of 15.4 kDa analyzed by reducing SDS-PAGE.
