背景	Interleukin-21 (IL-21,Interleukin-21,IL21,Za11) is a ~18 kDa protein. Cytokine with immunoregulatory activity. May promote the transition between innate and adaptive immunity. Induces the production of IgG(1) and IgG(3) in B-cells. Implicated in the generation and maintenance of T follicular helper (Tfh) cells and the formation of germinal-centers. Together with IL6, control the early generation of Tfh cells and are critical for an effective antibody response to acute viral infection. 1. Parrish-Novak, J. et al. (2000) Nature 408, 57-63.
