INTERLEUKIN-21 (IL-21) AND IL-21 RECEPTOR (IL-21R) MODULATION OF REGULATORY T CELLS AND FORKHEAD BOX P3 (FOXP3)

摘要

Methods of modulating the level and activity of Tregs and Foxp3 using modulators of IL-21/IL-21 R, i.e., IL-21/IL-21 R agonists (i.e., IL-21 agonists and IL-21R agonists) and IL-21/IL-2 I R antagonists (i.e., IL-21 antagonists and IL-21 R antagonists), are disclosed. IL-21 /IL-21 R agonists and antagonists can be used to enhance immunity or induce immune suppression in vivo, ex vivo and/or in vitro, e.g., for treating, ameliorating or preventing autoimmune or inflammatory disorders, cancers, and infectious disorders.
