The receptor of the cytokine interleukin 2 (IL-2) plays a crucial role in the regulation of the immune response. Binding of IL-2 to the receptor (IL2R) on the surface of T-lymphocytes triggers a series of intracellular signals that result in activation and proliferation of resting T cells. Research has found sIL2R is present in elevated levels with neoplastic diseases, autoimmune diseases, organ allograft rejection and different infections. It appears the sIL2R is an indicator of a wide spectrum of disorders involving immune activation.
