Product information "IL-21 (human):Fc (human) (rec.) (non-lytic)"
The extracellular domain of human IL-21 (aa 32-162) is fused at the C-terminus to the Fc portion of a mutant human IgG1. Lyophilized from 0.2µm-filtered solution in PBS. Shows the biological function of the IL-21 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain. Interleukin-21 (IL-21) is a key factor in the transition between innate and adaptive immune responses secreted by activated T cells. The IL-21 receptor (IL-21R) is expressed in lymphoid tissue, in particular by NK, B, T and dendritic cells, macrophages and endothelial cells. Recent evidence suggests that IL-21 plays a supportive role in the proliferation of T and B cells and influences the cytolytic activity of natural killer cells. IL-21 has been shown to up-regulate genes associated with innate immunity and to inhibit the differentiation of naïve T helper cells. IL-21 specifically inhibits IFN-gamma production from developing TH1 cells and is preferentially expressed by TH2 cells. Furthermore IL-21 has been identified as a growth and survival factor for human myeloma cells. IL-21/IL-21R interactions have a unique role in sequentially activating both innate and adaptive immune responses against poorly immunogenic tumors, leading to tumor rejection that is perforin dependent but IFN-gamma independent.
