Background
The pleiotropic interleukin-2 (IL-2) cytokine is a central modulator of immune responses by shaping the differentiation and effector function of T cells. The IL-2 receptor α (IL-2Rα) is the unique chain of the trimeric IL-2 receptor and increases affinity and cells’ responsiveness to IL-2. IL-2Rα can be cleaved by different proteases resulting in soluble IL-2Rα (sIL-2Rα). Contrary to cell-bound IL-2Rα, several studies point to an antagonist role of sIL-2Rα on IL-2 signaling by interfering with binding of IL-2 to the cell-bound receptor and diminishing STAT5 phosphorylation, thereby inhibiting induction of the expression of cell bound IL-2Rα and increasing differentiation of the T cell response towards a T helper 17 phenotype, a T cell phenotype normally inhibited by IL-2.
