Interleukin-2 soluble receptor α
IL-2 receptor alpha
IL-2 sRalpha
  

The function of IL-2 sRα is unclear. Increased levels of IL-2 sRα in biological fluids correlate with increased T & B activation and immune system activation. Results of a number of studies suggest a correlation between levels of IL-2 sRα in serum with the onset of rejection episodes in allograft recipients.
