Recombinant Rat Interleukin-21
Interleukin 21

Interleukin-21 (IL21) is a pleiotropic cytokine produced by CD4+ T-cells in response to antigenic stimulation. Its action generally enhances antigen-specific responses of immune cells. The biological effects of IL21 include induction of differentiation of T-cells-stimulated B-cells into plasma cells and memory B-cells, stimulation of IgG production with IL4, and induction of apoptotic effects in naive B-cells and stimulated B-cells in the absence of T-cell signaling. Additionally, IL21 promotes the anti-tumorigenic activity of CD8+ T-cells and natural killer (NK) cells. IL21 exerts its effect through binding to a specific type I cytokine receptor, IL21R, which also contains the gamma chain (γc) found in other cytokine receptors, including IL2, IL4, IL7, IL9 and IL15. The IL21/IL21R interaction triggers a cascade of events which includes activation of the tyrosine kinases JAK1 and JAK3, followed by activation of the transcription factors STAT1 and STAT3.
