IL-15 receptor α (IL-15Rα) is a cytokine receptor with the structural homology to IL-2Rα (CD25). Both α receptors contain a group of β sandwich protein called sushi domains. Similar to IL-2Rα, IL-15Rα is able to form a heterotrimer with their β chain (CD122) and common γ chain (γc, CD132). But unlike IL-2Rα subunit, IL-15Rα itself binds to IL-15 with equivalent high affinity compared with the heterotrimeric complex. IL-15Rα is expressed as soluble or transmembrane forms by variety cells, such as activated monocytes, dendritic cells, CD8+ memory T cells, NK or NKT cells. IL-15Rα by itself forms stable complexes with IL-15 on cell surface and presents IL-15 in trans to neighboring cells. IL-15, like IL-2, is a pleiotropic four-helix bundle cytokine and plays a key role in promoting T and B cell survival and proliferation, preferentially in memory CD8+ T cell proliferation, and NK/NKT cell development.
