Background: IL-21
Interleukin-21 (IL-21) is an approximately 14kDa four-helix-bundle member of the family of cytokines that utilize the common gammachain( gamma c) as a receptor subunit. gamma c is also a subunit of the receptors for IL-2, IL-4, IL-7, IL-9, and IL-15 (1). IL-21 is produced by activated Tfollicular helper cells (Tfh), Th17 cells, and NKT cells (2-6). It exerts its biological effects through a heterodimeric receptor complex of gamma c and the IL-21-specific IL-21 R (2,7). Tfh-derived IL-21 plays an important role in the development of humoral immunity through its autocrine effects on the Tfh cell and paracrine effects on immunoglobulin affinity maturation, plasma cell differentiation, and Bcell memory responses (4,8,9). It is also required for the migration of dendritic cells to draining lymph nodes (10). IL-21 regulates several aspects of Tcell function. It co-stimulates the activation, proliferation, and survival of CD8+ Tcells and NKTcells and promotes Th17 cell polarization (3,5,6,11,12). It blocks the generation of regulatory Tcells and their suppressive effects on CD4+ T cells (13,14). IL-21 R engagement enhances the cytolytic activity and IFN-gamma production of activated NKcells but limits the expansion of resting NKcells (15). In addition, IL-21 suppresses cutaneous hypersensitivity reactions by limiting allergen-specific IgEproduction and mastcell degranulation (16). Dysregulation of the IL-21/IL-21 R system contributes to the development of multiple immunological disorders (1,17). The 133amino acid (aa) mature human IL-21 shares 63%and 61%aasequenceidentity with mouse and rat IL-21, respectively. Alternative splicing generates an additional isoform with a substitution of the C-terminal 16amino acids (18).
