Flow cytometric analysis of 4% paraformaldehyde fixed 90% methanol permeabilized 293T (Human embryonic kidney epithelial cell) transfected with HA tagged IL-21 construct cells labelling Il21 with ab227837 at 1/500 dilution (0.1ug)/ Right (Red) compared with a Rabbit monoclonal IgG (ab172730) / Left isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.

Flow cytometric analysis of 4% paraformaldehyde fixed 90% methanol permeabilized Th17 polarized Mouse splenocytes were treated with 500ng/ml PMA and 500 ng/ml ionomycin for 1 hours, then add 1ug/ml Brefeldin A for another 4 hours cells labelling Il21 with ab227837 at 1/500 dilution (0.1ug)/ Right (Red) compared with a Rabbit monoclonal IgG (ab172730) / Left isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody. IL21 is mutual exclusively expressed with IFN gamma (Th1 marker).Cells were provided by an anonymous collaborator.

Target data

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 (PubMed : 15100251). 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 (PubMed : 23045607). May play a role in proliferation and maturation of natural killer (NK) cells in synergy with IL15 (PubMed : 11970879). May regulate proliferation of mature B- and T-cells in response to activating stimuli. In synergy with IL15 and IL18 stimulates interferon gamma production in T-cells and NK cells (By similarity). During T-cell mediated immune response may inhibit dendritic cells (DC) activation and maturation (PubMed : 12893770).
